There's a pretty great book on this called The Mom Test by Rob Fitzpatrick:

https://amzn.to/383bo92

It talks at length about the challenges, especially, of getting _honest_ feedback from prospective users. And it has a lot of ideas to that effect.

this2shallPassonJune 13, 2020

Sounds good so far. Look into making personas, a sort of summary abstraction of types of users and their context.

Ask good questions. Read The Mom Test. Here's a summary: https://www.slideshare.net/xamde/summary-of-the-mom-test

johnmarcusonMar 31, 2020

I would also recommend 'the mom test' audiobook. It's a wonderful book for new entrepreneurs.

charly1811onMay 3, 2020

I also read the Mom Test! I'm almost done with the book it's been a great resource to learn from! My telegram is https://t.me/celoubao we can schedule a call or direct message from there if you want

tmalyonSep 14, 2019

Getting really good at conversation helps.

Two books I would recommend are

How to Win Friends and Influence People

And

The Mom Test

cercatrovaonFeb 26, 2021

A similar book is The Mom Test. You're not supposed to let the user find how they would've solved the problem (as had they known, they would've solved it themselves), you're supposed to understand their pain points and then design the most effective solution for them.

renewiltordonJuly 24, 2020

Read the comments first and thought this was going to be crap. Instead it's great! Good read. Also read The Mom Test.

xwowsersxonNov 11, 2013

Recently read "The Mom Test" which had some good advice about how to avoid the positive feedback that people only give you because they want to spare your ego or whatever. Not exactly applicable to this post, but still some pretty relevant ideas in there which I've made good use of.

sharmionAug 14, 2018

Most insightful questions. Also kinda like a cheatsheet.

I went on to read The Mom Test after pondering over your message. It reflects the learnings from "The Mom Test"

hmhrexonMay 28, 2019

Thanks to you, I finally read The Mom Test. It was extremely insightful alongside your written experience.

djohnstononApr 2, 2021

I would recommend reading "The Mom Test". You can knock it out in a few days and it's got some pretty good insight on finding the right people and also getting meaningful feedback.

ensiferumonJuly 22, 2021

Most of these fall under the term "product - market fit". All key points really. Fail at the these and it's an uphill battle to acquire and esp. Retain customers.

Good stuff to read "the mom test" and "sell more faster".

cutemonsteronMay 23, 2021

I'm thinking one underlying mistake was to not have read a book like "the mom test" before trying to monetize faker.js?

I.e. not first finding out if it's something people want to pay for, before building the SaaS.

A mistake that's easy to do

rcavezzaonDec 3, 2016

I read an amazing book on customer development: The Mom Test by Rob Fitzpatrick - https://www.amazon.com/Mom-Test-customers-business-everyone/...

The first few pages blew my mind. It was a great read all the way through.

NeilRamponAug 25, 2020

Did you read the whole section of the post where I recommend reading The Mom Test.... ;-)

p.s. I've read Lean Startup, but will check out The Launchpad, thanks!

canadapupsonOct 1, 2018

Come on... most MBA programs are 2 years of full time study. You really going to compare "just Google it" or "digesting some key books like The Mom Test" to a MBA program? To push the logic further, what if it was a Harvard or Stanford MBA?

jeffshekonDec 21, 2019

https://www.indiehackers.com/ is a great resource around this.

The Mom Test (Book) is a way to verify the thing you're building people will actually want. Providing market-fit can be hard.

Startup School by YC is another good resource to keep you accountable and make progress with your ideas.

s1mononAug 13, 2018

The Mom Test is a quick read, and will answer all these questions. The name comes from the idea that asking your mom what she thinks of your brilliant product concept is generally the opposite of what you should be doing. http://momtestbook.com

mattbeeonSep 16, 2020

This is good advice but it's more tightly expressed in The Mom Test by Rob Fitzpatrick (my all purpose response to most SaaS sales blogs).

pembrookonMay 29, 2020

Read The Mom Test for a quick overview of how to avoid this problem.

vincentmarleonApr 1, 2021

I wish this book wasn’t called the Mom Test, people I’ve recommended it to didn’t take it seriously because of that. But it’s definitely one of the best books ever written on problem validation.

jasfionMay 6, 2021

What your target market wants is not that easy to determine. I've heard the book "The Mom Test" is a good read to help with this. I've started reading it recently.

jryan49onSep 5, 2018

I highly suggest reading "The Mom Test"

newbie578onJuly 24, 2020

The Mom Test is a must read! Only when you read it, do you realize how wrong your previous approaches to business validation were.

spIrronApr 19, 2017

Two books that can help understand it in more detail:

. The Mom Test - good and bad questions for customer discovery

. Competing Against Luck - introduces the concept of "jobs to be done" - people are hiring your product for a specific job they need to get done

NeilRamponJuly 30, 2020

I think customer interviews are definitely part of the mix, if done right (have you read The Mom Test?), but they don't give you 100% clarity. Perhaps just a more solid hypothesis...

autheticityonMay 14, 2021

What do your users say and do?

Do you know about user interviews and user research? Here's a great short intro: https://www.slideshare.net/xamde/summary-of-the-mom-test

I strongly recommend learning about product management and user research. Read The Mom Test and The Lean Product Playbook and do what's relevant. Start there!

Happy to discuss more and share more resources that could help. Email in profile.

chegraonApr 2, 2021

Hmm... I just read a great book by Rob Fitzpatrick that talks about having customer conversation. It's called The Mom Test.

I did a summary here: https://www.chestergrant.com/summary-the-mom-test-by-rob-fit...

I recommend getting a copy, solid advice from a past y-combinator founder.

andycrawfordonJan 17, 2021

Thinking, Fast and Slow – Daniel Kahneman

The Right It - Alberto Savoia

The Mom Test - Rob Fitzpatrick

Combining these and your chances of success have just increased by 500%

tmalyonMar 21, 2017

I just started reading The Mom Test. I highly recommend it. Your questions, even pretending to be about your brothers idea, are still introducing a bias. You will get bad data. The book shows what type of questions you should be asking to avoid these issues.

mindcrimeonJuly 20, 2020

The Four Steps to the Epiphany

The Startup Owner's Manual (note: this and the entry above are sorta/kinda the same book, just different editions. But there's enough difference between the two that I recommend both)

The Art of the Start

The Lean Startup

The Mom Test

grwthckrmstronMar 29, 2020

Read - The Mom Test

And then build in the real world.

marcus_holmesonApr 21, 2017

Stop thinking about selling your idea to your customers.

You're talking to them in order to understand the problem that you're trying to solve.

The best book on this that I've read is "The Mom Test", well worth the price

aloukissasonDec 29, 2019

A few stand out:

- Vagabonding (Potts): made me travel more than ever

- Steve Jobs (Isaacson): amazing life story, beautifully described

- The Mom Test: required reading for any young founder/PM IMO, I've gifted this more than any other book

- It doesn't have to be crazy at work (DHH/Fried): best advice on how to run a company in a sustainable way to maximize team happiness & output

- Masters of Doom: epically entertaining, super nostalgic

oakstonNov 3, 2020

I think it depends a bit on what type of feedback you're after. For quantitative feedback tools like hotjar.com's surveys can be quite effective (https://www.hotjar.com/tour/#polls).

For qualitative data such as user interviews/calls the solution for most teams is either to spend a lot of time on find users to talk to and set up calls or to pay companies like usertesting.com for access to their panels.

These tools don't allow you to get quick (and for most teams affordable) access to your own users for user interviews though, which is something that was enough of a pain point within my own team that we've built a tool exactly for that (https://tryribbon.com).

The Mom Test is also a great read on how to get useful user feedback in general (https://amzn.to/383bo92).

this2shallPassonJuly 16, 2021

You're welcome!

Lucky indeed. Their resources are so valuable. The Mom Test is always worth a re-read, I recommend it so often to people.

I understand the tendency to be broader and speak to more different people (larger target market, more potential buyers), but it makes it harder to effectively communicate your message in the language of the buyer. Also different people have different priorities. The more focus, especially at first, the better.

Do some experiments and see who has the problem in the most pressing way, or who can and is willing to pay enough to solve it to make it work for you and them. Consider size of company, decision maker, potentially industry/sector, location, time since money raised, bootstrapped vs investor funded, anything that makes sense - you never know which niches will be amenable to you.

ddtayloronMay 17, 2019

Same here. I am in the process now of checking out The Mom Test book and seeing how we failed in getting soft interest.

jh88onJan 14, 2021

Have you read The Mom Test? https://www.amazon.com/Mom-Test-customers-business-everyone/... Also, Rob Fitzpatrick did a youtube series focused on remote interviewing https://www.youtube.com/watch?v=bcWqxq2fJgY&t=1s

ghufran_syedonJuly 16, 2021

totally agree - I fell into this trap before of mistaking “customers think it’s a good idea” for “customers will pay”

This video from yc explains how most of our conversations with (potential) users are at best useless and at worse misleading, and how to do it better. Based on the book, “The mom test

danielbarlaonJune 15, 2018

On the topic of asking people about your idea, I was once having a bit of a problem with this topic. Everyone seemed to "love" what we were busy with, and they'd throw in some suggestions on what else we could do to make our product more suited to their needs. I thought this was great; we're on to something, right?

A little bit later, I relayed these situations to someone who was giving advice on where to take the product / business, and he pointed out that these low-effort supportive comments and "please add feature X" suggestions are ways in which people brush you off in a non-confrontational way. He pointed me to a pretty good book called The Mom Test, which goes through the reasons why this is the case, and also how and what type of questions you should ask. Highly recommended reading, it was eye-opening for me.

tomcamonDec 30, 2020

We had a bunch of good ideas the world didn’t care about. For example, actual user IDs and a feedback system. We launched it as an add-on for radio station websites and learned that they were an endless source of feature requests, which we foolishly granted. Finally, it didn’t scale well because a lot of behind the scenes content moderation was necessary.

Mostly I blame myself for not validating the idea properly. If “The Mom Test” book had been around at that time I could have saved that money and a lot of strain on my marriage. I feel strongly that it is by far the most important business book to be published in the last three or four decades.

haltingproblemonApr 4, 2021

This is a great writeup and thank you for sharing with so much candor. You are light years ahead of everyone who has ideas and has not tried them and learnt the lessons.

You learnt experientially what most either never learn or a rare few learn from books like The Mom Test. Even compared those who read the book and get it, I fear it does not translate to a lived earned experience.

Take some time to rest, recuperate, recharge and go build #4!!

tomcamonSep 16, 2019

I don't make these pronouncements often, but what you need to know is settled science ;) If you read then actually follow "The Mom Test" you'll get the answers you need. To me it's one of the most revolutionary books in business and should be required reading for anyone doing a startup.

No relation to the author, I don't make money off the recommendation, etc.

EdmaronAug 8, 2019

1) Regarding the bias on friends feedback I highly recommend you the book "The Mom Test". It's a great read on user interviews for product validation.

2) Have you tried cold emailing people? It tends to work better than linkedin in my experience. Look for people who blogged or tweeted about topics related to your product. Not everybody will respond but people that the time to share what they know have a tendency to help other people.

jkkornonJune 25, 2020

I've had that question mulling around in my head for a few years.

Like others have mentioned, of course there's an element of luck. It helps to have a product that fits the zeitgeist.

But in my experience, the remaining 99% is all working smart and understand what and the "why" of the problem at hand.

The Google Ads technique is good, but only if you're working on a product with a known problem. For anything new... it probably won't be much help on it's own. It's useful though if you use to see how people try to solve known problems.

Best resources hands down IMO for understanding 0 to PMF are:
The Lean Product Playbook by Dan Olsen. Gives a good view on how products fit with the market. If the problem space is wobbly, the solution space will suck.
The Mom Test by Rob Fitzpatrick (my favourite). Excellent book on user interviews. It's so good that I made a primer out of it: https://gum.co/DeSxL
The PMF Engine by the founder of Superhuman: https://firstround.com/review/how-superhuman-built-an-engine...
It's a more quantifiable way of approaching it.

areichertonNov 17, 2020

It's amazing to me what a skill it truly is to be able to talk to customers/users, and come out of those conversations with valuable/actionable insights.

As an engineer, it's _so_ easy to fall into the traps she mentions ("not really listening to your users and [...] building something you think people want", or becoming "more focused on the excitement of the technical challenge than your users").

Until I actually tried starting a business, I always scoffed at this advice -- "obviously I won't make those mistakes!" But I still find myself goofing up over and over. It's so attractive to think that "this one new feature will make all the difference, so I should probably just focus on coding rather than talking to users."

Has anyone found a particularly effective way to overcome this? Is it just a lack of discipline on my end? (Maybe I need to reread "The Mom Test" a few more times...)

The Mom Test” by Rob Fitzpatrick is in my mind the most revolutionary and essential business book for indie hackers in the last 20 years. It would have saved me $1.4 million in my attempt to beat craigslist at its own game a decade ago.

It illustrates in the most logical progression a set of easily implementable steps to ensure that your own confirmation bias doesn’t sink your company.

donwonAug 31, 2017

> In July a friend of mine, who is a mac user, said she wouldn't even consider looking at fontforge on her mac unless it behaved more like a mac application. So I figured out how to build a mac Application...
>
> My friend still (November) has not looked at fontforge. Ah well.

This is a great example why user feedback needs to be taken in close proximity to a salt mine.

We, or at least most of us, being human, have a horrible job anticipating our future emotional state. So when his friend said that she'd be interested if FontForge was available on her Mac, she probably meant it, but her request didn't reflect the underlying reasons she held for not using the software.

Not out of dishonesty or malice, but because she probably didn't know herself. It's like all those times somebody swore they would love to have an app that frobnitzed the foobars, but when said app became available, it was met with a chorus of shrugs and mehs.

There's an excellent book on this topic -- The Mom Test -- that anybody building products should read.

irjustinonFeb 28, 2020

Fantastic post. Lots of weight on the problem discovery area which is the right move and engineers turned entrepreneurs skip this step a lot. I know I did.

A book recommended by YC's Aaron Epstein is The Mom Test[0]. The first 50-60% of the book is dedicated to how to discover problems with end clients/users that are worth tackling.

I have used the techniques personally and it's great to see what users say is a huge problem vs a problem they're willing to pay for.

It is easy to get stuck in a self-fulfilling trap that a user complains is a big problem. I recently spoke with a customer:

- "What's your biggest problem?" (book says this question is a no no)

- He replies, "If I sell 3 cars at the same time, I'm out of available float (cash) while I wait for those deals to close. This is a HUGE problem for me!"

- "How do you solve this today?" I ask.

- "I have other, larger car sales company who will lend me money at XX rates."

Right there, it's a solved problem. The end user figured out their own way. Turns out other smaller dealers like him rely on large trade line companies.

The only way I could complete is either on lower cost of financing or speed. At which point, for me, it's not a problem worth solving. The problem isn't so big for him where he's willing to throw cash at me for it.

Talk to users.

His writing style seems similar to Hunter Thompson’s - I wouldn’t read into it too deeply, exaggeration is the backbone. Personally I enjoy it.

As for the actual content, there’s a massive difference between customers dying to use your product and them telling you it’d be “neat”. People don’t buy “neat” products. This is why you talk money to them as soon as possible. No real surprise it didn’t work out for him, the incentives just aren’t there.

He could have prevented all this by reading the Mom Test - oh well, experience is the best teacher anyways.

flipchartonJan 17, 2019

Just finished reading a book called "The Mom Test" by Rob Fitzpatrick. The central idea of the book is to get you to ask the right questions, because if you ask people questions like "how am I doing", friendly people will tell you "yay" because they don't want to hurt your feelings, while assholes who want to appear like gurus will tell you "nay" to bolster their own notions of being a startup soothsayer.

Highly recommend it. It's short (yay!) and very practical and changes the way you think about questioning people.

No affiliation, just like the book

carpoonMay 7, 2020

Read and/or listen to books that give you tips on building products. Most importantly use the skills you learn about.

Don't try and do everything in the book. Try and take one or two things that resonate with you and just implement those. Obviously you need to be involved in the development of a product to do that.

For example, I listened to The Mom Test earlier this year. Instead of trying to remember and do everything from the book, I just took one part that resonated. For me that was "Don't talk about your product when interviewing customers, talk about the customer and their problem.". When you feel you've improved at that, move on to the next thing you can improve.

this2shallPassonJuly 14, 2021

Have you read The Mom Test? Highly recommended. Here's a summary: https://www.slideshare.net/xamde/summary-of-the-mom-test

- Exactly who is your ideal customer, and what do they care about? Veteran CEO of 4 person seed stage start up in FinTech world trying to build an MVP? Mid career hiring manager at a Series B or C company in healthcare looking to expand their team long term? Recruiter at a Series D company with 20,000+ employees trying to meet their quota of leads for the week? Someone else? Drill down here. Once you identify it and validate that through experiments, focus on as few as possible - ideally just one.

- Is it clear to your potential customer what problem you are solving for them?

- Do they think you are the best way for them to solve it? What alternatives do they use currently? What's painful about it? What's better about your solution, so compelling that they should try it?

- Is the problem they think you solve one of their current
priorities?

If the issue is with framing or marketing, here's a useful guide: https://www.julian.com/guide/growth/intro

Good luck!

mtlynchonFeb 2, 2021

Thanks for reading! Congrats on starting out on your own.

>However, I am still quite unsure how to actually get the ball rolling. My current game plan is to just brainstorm for a week or so and then start building the best idea I came up with during that week, then give myself a release deadline of one month for an MVP and see if I can raise some interest.

That mostly sounds sensible to me.

I recommend thinking more about the "raise some interest" part. There's a common trap that indie founders frequently fall into (myself included) where you build an MVP but don't think about marketing it until you've already built it. And then you realize there's no plan for finding customers.

Once you build the MVP, how will you find customers? Can you skip to that part without even building the MVP?

One of the ideas I liked in the Jason Cohen video[0] I linked in the article how he built WP Engine. He wanted to build a product for WordPress consultants, so he just emailed consultants and offered to pay them their hourly rate if they'd jump on a call with him and answer questions about their pain points. He didn't have any demo to show them, but people took his calls because he was showing that he valued their time (most accepted the calls and declined the money).

So, I think building an MVP is great, but it's even better if you can talk to customers before you build anything and find out what problems you can solve for them. A great book for this is The Mom Test by Rob Fitzpatrick, for which I've published my notes.[1]

Two classic books that are fast reads and will also help you are 1) The Launchpad (about YC) and 2) The Lean Startup. Both are old books but they cover many of the same concepts and ways of thinking.

I’d add that if you do nothing else, read the first 3 chapters of The Mom Test; it provides a great overview for evaluating ideas.

keithnzonOct 17, 2018

One book that came up recently on another thread ( and probably quite a few others as it is written by a YC founder) is "The mom test". I just read it recently, and it is really good! it has an emphasis towards tech people but the advice is applicable to everyone. It essentially guides you to be very clear about what what you want to get out of your interactions with people, avoid people giving you misleading information ( like "wow, great product" when they aren't really interested but don't want to discourage you ), recognizing real commitment from people vs niceties, and having a conversation strategy that leads to good info.

james_impliuonFeb 23, 2020

We launched a 1:1 tool for sales managers that used predictive analytics to suggest which deals needed to be discussed (ie Deal X looks like it's stuck). The reason being, when I was a sales manager, I found people would naturally talk about positive stuff rather than easily giving the whole picture.

It failed because quite simply, when we tried to get other sales managers to use it for free (hoping it'd be popular), we found they wouldn't make the time to spend 2 mins planning a 1:1, probably as they're managed on 'selling deals, right now' in many cases, which is a bit sad!

Learning: I should have read the Mom Test.

With hindsight, I wish I'd built it for engineers based on Pull Requests (PR #181 had a ton of back and forth / NLP shows it got heated). It would have been fun if nothing else!

tmalyonOct 6, 2017

1. scan online forums for common problems if one exists. This is a manual effort, but it can pay off as you will be building something that is already in need.

2. do some customer development, but be very careful about introducing bias into your questions. This would give you bad data if you ask the wrong types of questions. See the book The Mom Test

3. listen to a few podcasts where founders are interviewed. The older YC podcasts are really good. If your going for a two sided market, I would caution you. This is more challenging than other types of ideas.

quickthrower2onMay 27, 2020

This is a step in the right direction from coding first and then hoping people will come.

I think you need more than a count of subscribers to validate your idea though. Ideally you can engage them so you can have conversations will a decent sample size (see the book "The Mom Test" and similar on what questions to ask), and you will know a lot more than just "I got 318 subscribers from HN" or whatever. I can't tell you how many hours I've wasted trying to sell stuff to uninterested lists of even 3000 people and getting nothing.

I'm in a different country to you, and sample size of 1 speaking here, but I'd never sign up your page because you are dealing with money and stocks and I don't recognise you as a banking institution. So I wouldn't waste my time. I've been stung enough by trading platforms run by pig players. I'll use the boring big banks thanks. Things might be different in India though. Unless you are the ex-CTO of Barclays and have $100M in funding or something. Plus its such a competitive landscape that unless you are paying me to trade I can get very good deals out there.

However I might sign up for a tool to help me calculate options prices, or can tell me which shares internationally have falling the most since the COVID pandemic started. That's safe, I'll soon know if it doesn't work properly and it might be handy. Having signed up for that I might answer a survey you send me, and then you'd know more about me. Maybe I'm happy with my broker but I have a big problem with X that you can solve.

tmalyonMay 31, 2017

There are two great books that helped me do this.

First, the Mom Test, it is very short, and it talks about what types of questions to ask and what types to avoid. The main focus is avoiding the introduction of bias. You want good data you can work with.

Second book is Running Lean. It has a great script that you can adapt to the industry you are targeting. It also gives pointers on conducting the interview.

Together, these two short books will get you started.

pimterryonAug 6, 2019

This is both really interesting, and excellent advice.

I've been working on exactly this myself, and while I'm lucky enough to have found an initial handful of customers from the classic blind selling of my product, it's ridiculous how much I've learned & reevaluated things using the actual feedback & conversations with those customers.

For other people wrestling with this, one thing I'd suggest is reading The Mom Test: http://momtestbook.com/. Great intro into exactly how to handle those feedback conversations, who to talk to, and how to talk to them, even if you don't have any product at all.

I've spent a ton of time as a developer trying to make money from various side projects and businesses. So most of my top "wish I'd discovered this earlier" list revolves around tech+business stuff:

* Strategy #1: Charge more. patio11 has been shouting this from the rooftops for years, but it didn't sink in until after I started Indie Hackers[0]. If you charge something like $300/customer instead of $5/customer, you can get to profitability with something like 50 phone calls rather than years of slogging. It's still hard, but it's way faster.

* Strategy #2: Brian Balfour's four fits model[1]. It's not enough to think about the product. You also need to think about the market, distribution channels, and pricing, and how each of these four things fit together. I imagine them as four wheels on a car. It's better to have 4 mediocre wheels than 3 great ones and a flat.

* Book: The Mom Test.[2] Amazing book about how to talk to customers to research your ideas without being misled, which is a step I've stumbled on before.

* Tool: Notion. I just discovered it recently. I use it for all my docs and planning.

I respect your opinion, and if you're the type of person who considers that a blanket conflict of interest than our book isn't for you.

I don't consider that good or bad, it just is. Similar to how some people prefer fish over meat and vice versa.

However, I will push back against the broad stroke generalization that you either teach people for free or charge money and be considered a scam.

Our advice is solid and battle-tested. There's Rob who wrote the Mom Test and Devin who wrote The Workshop Survival guide with Rob. And then there's our community with over a 100 up and coming authors who we're helping increase the probability of success through our process. The early results are already positive and it'll only improve as we keep trying to nail our process even more.

Is YC a scam because it isn't free?

If an author is like Tai Lopez you don't get word of mouth and burn through your lead pool. That means you're constantly trying to attract fresh leads, which is why these scams eventually tend to break.

What we're doing is teaching a process that minimizes some of the common mistakes authors make. Yes, we're charging money for that.

But if you look at our process, or heck, just read this article, you should be able to see that there's value worth paying for.

If you use nothing else but this article with these 4 common pitfalls to avoid, you'll do better vs. not having read it. And this was free.

So, I don't think your argument holds any water.

These books apply to pretty much any type of product:

"The Mom Test" by Rob Fitzpatrick will teach you how to figure out what your customers really want, because it is almost certainly not what they are asking for.

"How to Make Sense of Any Mess" by Abby Covert. How to organize and present information.

"To Sell is Human" by Dan Pink. This is how you should look at sales and marketing.

Assuming you are going to be building software:

"Seductive Interaction Design" by Stephen P. Anderson.

"Planning Extreme Programming" and "Extreme Programming Explained" are must-reads for working with software teams.

I've worn both product and engineer hats on my path to being a sort of rentable CTO, and am always happy to help out people that are getting started as a PM -- email is in the profile.

Good luck!

I'd go on Craigslist or something and talk to landlords first, preferably in person. Try to figure out if they're actually interested in buying, and don't write a single line of code before you have an actual sale (have them pay you cash if necessary). If you're not sure what to ask I'd recommend the book "The Mom Test" (not affiliated to it). The basic gist is that you need to be careful which questions to ask so you don't bias the person you're questioning. For an obvious example think of going to your mom and telling her in an excited tone of voice "Hey mom I have this great idea, what do you think?", it'll probably be really hard for her to tell you that she'd never pay for that idea. Same applies to potential customers.

Anyways, I'm in the same boat as you (I'm looking for the exact same kind of problem as you), so if you wanna bounce some ideas, shoot me an email: a (dot) v (dot) f (at-sign) gmx (dot) at

Hey HN,

I'm Daniel Ch: /r/SaaS moderator[1], founder, etc. I'm launching to HN this podcast, "Talk To Your Users": https://anchor.fm/talktoyourusers

I've previously tested an idea on Twitter [2] (in typical 'talk to your users' validation fashion) and on subreddits [3]: live examples of 'Talk to your users'

The feedback seemed interesting, so... I am now launching it!

What's the idea? - I record (with consent) conversations with users. People that are/will/were users of my product. Why?

Situation: One of the top advice bits in the startup/product world is: talk to your users. PG said it multiple times, but double-stressed it by saying: Half the advice I give to startups is some form of "talk to your customers." And then there's The Mom Test: a book about how 'learning if your business is a good idea when everyone is lying to you'.

Problem: Ok, any practical examples? I mean me listening to founder X talk to user Y. With good and bad examples

My solution: I'm doing this: recording my conversations with users.

What product will I talk about? - The answer is: I don't fully know. I'm as of now building PriceUnlock.com, a tool that helps SaaS founders find&set the perfect pricing for their tool. But maybe due to the conversations, we'll see a pivot. Or two. Or maybe it'll all go well and I'll just 'talk to my users' about future features. Who knows where this takes us? But I'm launching today with 6 episodes.

Start with better understanding what exactly customer discovery is, Steve Blank and Eric Reis are good places to start.

To better understand how to conduct the discovery and what questions to ask you should read a bit of Rob Fitzpatrick's The Mom Test.

It's hard to give one piece of advice about how you should do customer discovery (without having a high quality conversation about what you are doing) b/c every venture is a different in what needs to be tested. Software ventures tend to need product customer discovery (what you should be building), while STEM companies[1] tend to need go-to-market strategy customer discovery.

[1] An example would be a company that is making an orally delivered anti-coagulant drug. They have HIGH technology constraints that aren't easily adjusted, so their customer discovery tends to revolve around questions about what their real value proposition is (is it pain free needle free drug delivery or no medical training drug delivery or something else) and other such questions.

nick-garfieldonJune 24, 2020

If you're in the "talking with customers" phase, you should also check out "The Mom Test" by Rob Fitzpatrick.

http :// momtestbook .com (EDIT: I just noticed this is an http site... breaking up the link into pieces for now. Sill recommend Googling the book)

The tldr; is that as soon as you tell someone about your idea, it's going to bias their subsequent answers. They're going to lie to, try not to hurt your feelings, want to get rid of you, etc. So if you're trying to validate an idea, the most important rule is "Don't talk about your idea".

What "The Mom Test" recommends is to instead ask prospective users about their lives and specifically to recall individual moments when they had the problem your idea will supposedly solve. With this "unbiased" recollection, you (as the entrepreneur) have to put 2 and 2 together to figure out if people 1) really have a problem and 2) are open/looking for a solution.

Added The Mom Test in my list of books to read / listen!

nmfisheronFeb 29, 2020

> A book recommended by YC's Aaron Epstein is The Mom Test[0]. The first 50-60% of the book is dedicated to how to discover problems with end clients/users that are worth tackling.

I can't recommend this book enough. It lists every single mistake I ever made and every lesson I learned in doing so.

The only problem is that I discovered the book after making those mistakes and learning all those lessons.

Of course, following the advice in the book won't guarantee a successful business. But I'm 99% sure that NOT following it is a sure-fire recipe for failure.

arnonejoeonApr 1, 2021

The book 'The Mom Test' is all about this.

photaweonFeb 11, 2020

I'm well into the second 1000 weeks (22 years of programming). I don't think there are any decent timeline hacks - just do something, see if it works, and if not, roughly after 6 months I suggest you stop, and take a 6-12 months break. Then, try something else.

I've tried and failed quite a few times (10+), and my current experiment - while I think it's a successful one, time will tell.

One thing I would suggest is you read "The Mom Test" book -- I think it'll serve you well in the long run (it's about marketing, and you'll need to do that if you develop your own products).

rcavezzaonOct 21, 2017

I like your comment and a lot of your thoughts are common. Allow me to help alleviate some of your concerns. I think the root of the issue is that many "Startup Tarpits" are not talking to the right customers early on. I also think you have only worked with marketing people who didn't use a methodical, scientific approach to user acquisition.

Don't hire a marketing expert. This is a bad first step. You should define a very specific subset of customers and talk to them. Find out their problems after talking to 10 very targeted people that fit into a user profile. I recommend reading "The Mom Test" (it's a book about how to phrase customer development interview questions) as a basis for how you talk to potential customers.

User acquisition efforts are not only measurable on a larger scale. You may have this idea because the people you worked with may have had a big company background. For a startup, it is very necessary for your advertising campaign to define a cost per click, find a conversion rate, and then test many different advertising phrases and avenues. This helps put a direct cost per user acquisition price on each campaign and you can compare apples to apples. It takes "voodoo money burning rituals" and turns it into numbers that are measurable.

If you rely on free marketing channels without a clear focus on who is using your product, it is very likely that you have 10 customers who fit 10 completely different segments with 10 different ideas of which features will give them value.

They key is learning. When you estimate future software releases, you typically point a story using things you have learned from previous, similar stories. When you attempt a new advertising campaign, you should use past learnings to determine which ads and messaging will work for different segments - how much they will cost, and how many users you can expect to get based on past results.

In summation, startup marketing should have a focused, scientific, numbers driven, methodical approach - just like writing software. If your marketers are not doing that, you probably aren't working with the right marketers.

Read the book: The mom test

tacononSep 11, 2018

My favorite book on customer development is "The Mom Test"[0], by a YCombinator alum. The name is terrible, but the content of that book is golden. He tells the terrifying story of talking to customers constantly as they wasted a million dollars building something the customers were not going to buy. There are various ways the customer pays you before the product is ready, and if they aren't paying you, they aren't really interested. Payment can be in the form of time (they meet with you), personal reputation (they recommend you to friends), company reputation (they arrange a meeting with their boss, or coworkers), etc.

Go read The Mom Test.

valehelleonDec 28, 2020

Not really. I think every person takes note differently and trying to cater to everyone is just impossible.

For example, right now I'm taking notes for customer validation process following the The Mom Test[1] book and existing note taking app is too general for my use case.

That is why I'm also in the mist of developing an app[2] that is solely focus on that particular use case.

During such an early stage, I would do it in an "inofficial capacity" - do you have friends at other companies who work in a similar role as you? I would reach out to them and gauge their reaction, from "sounds like a neat idea" to "oh my god, I literally spend 1 hour a day on this and I've been looking for a solution to this since forever. I (or my boss) would pay for this in a heartbeat!". I've found "The Mom Test" by Rob Fitzpatrick to be great for guiding you along this process step by step. When asking friends, there's the risk of running into something called "interviewer bias", where they will rate your idea more positively simply because they like you (and would have dismissed it if some random stranger had proposed the same idea), so that's something to watch out for if you go down this route. Good luck!

This question has been asked a thousand times.

On reddit: https://www.reddit.com/r/startups/search?q=how+to+validate+i...

On IndieHackers:

* go to https://www.indiehackers.com/
* click the search icon in the upper right
* type "how to validate idea"

Those 2 sources will give you hours of reading.

My short answer is that if you have to validate an idea then you're doing it wrong.

A good idea is a solution to a problem that you noticed. Maybe because you've had this problem yourself (e.g. "I was trying to share a screenshot with a friend but there was not tool to do it easily") or maybe because you noticed that other people have a problem that you can solve using your programming skills.

Lacing any additional context to your particular situation "validating an idea" conjures a situation where you came up with a solution first and then started thinking "is this a solution to a problem that someone actually has"? Which is backwards.

If you want to learn more about how to improve the skill of noticing problems, read "The Mom Test" (https://blog.kowalczyk.info/dailynotes/note/b4u674cvj43jdajd...).

rahimnathwanionMay 7, 2021

Rather than asking people which view they prefer and why, it might be better to build a better understanding of:

1. When do they look at their overall roadmap view?

2. Why?

3. What actions do they often take as a result (e.g. print it out for upper mgmt, drag around the timing, ...)?

4. Why do they need to do those things?

5. ...

I could be off base but, based on your questions, I'd suggest you dial up the time you spend interviewing your customers about their problems.

The book 'The Mom Test' is a great guide for how to put this advice into practice.

odie88onMar 28, 2020

Seconding The Mom Test. It's a fast read too, and the author was on a recent episode of the Indie Hackers podcast.

For more of the same, I got a lot out of Lean Customer Development by Cindy Alvarez. Here's a talk from Cindy if you'd like to get to learn more before committing to a book: https://www.youtube.com/watch?v=d5hc7sseHbE

maximponFeb 5, 2021

It's a little bit more intricate than that. The point is to figure out what the customer needs. The Mom Test (book) covers this pretty well.

This page just kind of pokes at things everyone's frustrated about without offering a solution. But, as The Mom Test points out, there are lots of things people are kind of unhappy with, but are unwilling to pay for. I think the example they use are shoelaces: "Are you tired of bending down to tie your shoes? Having to stop in the middle of the street to re-tie them? Feeling your shoelaces wear out over time? Getting stuff stuck in there?"

Maybe, but are you actually gonna pay for a shoelace alternative? Probably not.

This page is that. It makes some sweeping statements about how work should be intentional and peaceful, and says "we're gonna solve it with a calendar", without offering any details about what that calendar is actually going to do.

If they had some screenshots, they could learn something about how their users engaged with the product. Saying vaguely positive-sounding things ("Rise is different than your current calendar, because instead of starting with meeting invites from others, it starts with you.") doesn't teach them anything.

rdrdonMay 15, 2021

I appreciate your honesty, and sharing this may just save someone else from making a similar mistake with Upwork. So thank you.

Having read over this and a few other replies I would definitely say it would be worthwhile taking a step back now, don’t fall into the sunk cost fallacy and continue to burn through cash/time building things you think will help, spend a bit of time away from the keyboard, reading The Mom Test as others have suggested, it’s honestly a fantastic book, very actionable and probably won’t take you long to get through. That will put you in the right mindset for where you are in your journey and what you need to do next - which boils down to trying to validate some of your ideas, the correct way.

Finally you mention someone offering mentorship/advice, and you taking it, just be cautious with who you take advice from, the best person to take advice from is probably someone a few steps ahead of you, that means finding someone who may have just secured their very first bit of seed money as a solo/duo founding team, or an indiehacker who’s reached say $1000 MRR for a B2C app.

Good luck.

jonwachob91onApr 21, 2017

Read the book "The Mom Test" -> http://momtestbook.com. Even if you just read the first chapter, it'll help you out a lot.

To properly talk to customers to identify if there is a need for your product/idea requires for you to not bias them by telling them what you are working on. You should be able to talk to your mom about your idea without her ever knowing that you have an idea for a product.

tmalyonMar 29, 2017

I subscribe to some newsletters that aggregate weekly articles around some category or topic. This is a lot easier for me as I do not have to continually scan sources for new articles.

I also try to read a book or article on something new I want to learn. My most recent book I started reading is called the Mom Test. Its about doing customer development, and it touches on the subject of what type of questions you should be asking.

mtlynchonMar 28, 2020

Fellow aspiring solo founder here! Here are a few books/resources I've found helpful:

---

The Mom Test by Rob Fitzpatrick

This book stresses the idea of starting with customer interviews before you build anything and how to ask questions of prospective customers to get meaningful information when people's bias is to just tell you, "Yeah, that sounds like a good idea," even though they'd never pay money for it. I spent a long time trying to apply it, and the struggle was that in my experience, customers who don't mind diving deep into their unsolved problems for an aspiring founder are a disjoint group from customers who have serious money to spend.

My notes: https://mtlynch.io/book-reports/the-mom-test/

---

Start Small, Stay Small by Rob Walling

This is a bit dated, but I think it has valuable takeaways. The most important for me was the value in marketing to small niche customers. Big competitors are less interested in catering to niche groups, and the more specialized, the easier they are to find and market to (e.g., they all read the same magazine or attend the same convention).

My notes: https://mtlynch.io/book-reports/start-small-stay-small/

"Designing the Ideal Bootstrapped Business: Jason Cohen, Founder, WP Engine" (https://www.youtube.com/watch?v=otbnC2zE2rw)

A good recording of a MicroConf talk about useful things to consider when building a new Saas business.

> how do you find the time to build that idea out

Based on this, I'm assuming you want to build an idea that makes money first.

You need to solve a problem that's worth paying for. Easily said, of course.

The Mom Test[0] is a book about how to ask questions that are worth pursuing as a business.

> do some of the good ideas get left out?

That's the question really to focus on. Don't worry about developers or building yet - the first question to ask is - is there really a problem here?

The first step really is about a basic litmus test. What's the cheapest way to "test" the idea without a costly build? End user research, landing page with some targeted traffic,

All about getting to a few potential customers who will give you feedback.

After that, then I say start building.

If you build in a vacuum (you and some developers), you're likely to get it very wrong.

For a dating/social app what matters to users is the pool of other users. Are there enough users, etc.? and the answer is no (at this point).

I will look into the sources you shared. I have heard of The Mom Test and The Lean Product Playbook but haven't still had a chance to check them out. Will definitely do.

Thanks for the offer also. Will get in touch.

JowlCo41onJan 10, 2016

Always start with customer interviews. It sounds obvious, and even the people that do them can mess things up by pitching to early or leading customers to the answers they want to hear. THe best practice is to usually ask about past actions or behaviors rather than 'what will you do' or 'what do you want'. The term is called New Years Effect I believe, because obviously if you ask someone about getting in shape they will lie based on what they want to do, but may have never done before. Another great read is the book 'The mom test', to carry out realistic user interviews

mindcrimeonOct 22, 2018

There's a lot more to marketing than getting on the front page of HN.

OP, I suggest you read Traction by Gabriel Weinberg, and The Four Steps to the Epiphany by Steve Blank, and consider if you've successfully identified who your customers are, and a valid channel for reaching them. Further ask if you've correctly identified a problem that those customers will pay to have solved, and whether or not your product actually solves that problem. How do you do that? Talk to customers. All of this stuff is in the Steve Blank book.

Also consider reading The Mom Test[1] by Rob Fitzpatrick.

The big takeaway from this article for me was this line:

"Create a solution to somebody else’s problem, where that problem sits at the intersection of being genuinely interesting / meaningful to you and being something that you are reasonably capable of addressing."

I also want to second his book recommendation [The Mom Test](https://www.amazon.com/Mom-Test-customers-business-everyone/...). It's really short and will save you a lot of time building things nobody will pay for.

Why do I need a degree to read financial reports? Can't I get a book or just Google it?

If I'm running a business, why do I need to be able to read financial reports at all? Especially for some other random company. If I need to make a financial report, couldn't I use an online generator, template, accounting software, or hire someone to do it? Looking online there seem to be many services for less than a few thousand dollars for financial reporting.

If I have a product wouldn't I be able to take time to research applications for it thoroughly rather than relying industries that I remembered from some course.

As far as measuring clients worth, do I need a course on that really or do I just need to be aware that there are clients that will waste our time and try to get practical evidence that won't be the case.

Can I not get quite a bit of useful knowledge by reading and carefully digesting some key books like The Mom Test?

When you say think like a marketer, so far every article that comes up when I google that is listing things that any used car salesman would apply.

Just based on what you said it sort of makes MBA degrees seem like a waste of time to me.
