The Mom Test - Rob Fitzpatrick

Overview

Offers practical advice for entrepreneurs on how to gather honest, valuable feedback from potential customers. The book emphasizes that instead of asking people if they like your idea—which often leads to polite but unreliable responses—entrepreneurs should focus on understanding customers' actual problems, past behaviors, and needs. By asking about real experiences and specific challenges rather than hypothetical scenarios, this approach minimizes biased feedback and helps validate ideas more effectively.


Notes


  • A big mistake is almost always to mention your idea too soon rather than too late 

  • Talk about people and their lives to see if your idea fits in don’t talk about your idea 


Mom Test 

  1. Talk about their life instead of your idea

  2. Ask about specifics in the past instead of generics or opinions about the future

  3. Talk less and listen more


  • Rule of thumb: Customer conversations are bad by default. It's your job to fix them.

  • Rule of thumb: Opinions are worthless.

  • Rule of thumb: Anything involving the future is an over-optimistic lie.

  • Rule of thumb: You're shooting blind until you understand their goals.

  • Rule of thumb: Some problems don't actually matter.

  • Rule of thumb: Watching someone do a task will show you where the problems and inefficiencies really are, not where the customer thinks they are.

  • Rule of thumb: If they haven't looked for ways of solving it already, they're not going to look for (or buy) your


Good questions

  • Where is the money coming from? For b2b customers 

  • How are you dealing with it now? 

  • What else have you tried 

  • What are the implications of that 

  • Talk me through the last time that happened 

  • Why do you bother 

  • Who else should I talk to? 

  • Is there anything else I should have asked?


Three types of bad data

1. Compliments

2. Fluff (generics, hypotheticals, and the future)

3. Ideas



Remember you don't need to end up with what you wanted to hear in order to have a good conversation. You just need to get to the truth.

Here's a good conversation with a solid negative result:

  • "That meeting went really well."

  • "We're getting a lot of positive feedback."

  • "Everybody I've talked to loves the idea."

  • All of these are warning signs. If you catch yourself or your teammates saying something like this, try to get specific. Why did that person like the idea? How much money would it save him? How would it fit into his life?

  • What else has he tried which failed to solve his problem? If you don't know; then you've got a compliment instead of real data.


Rule of thumb: Compliments are the fool's gold of customer learning: shiny, distracting, and entirely worthless.


Fluff comes in 3 cuddly shapes:

  • Generic claims (*I usually", "I always", "I never")

  • Future-tense promises ("I would", "I will"

  • Hypothetical maybes ("I might", "I could")


Questions to dig into feature requests: 

  • "Why do you want that?"

  • "What would that let you do?"

  • "How are you coping without it?"

  • "Do you think we should push back the launch add that feature, or is it something we could add later?"


Questions to dig into emotional signals:

  • "Tell me more about that."

  • "That seems to really bug you — I bet there's a story here."

  • "What makes it so awful?"

  • "Why haven't you been able to fix this already?"

  • "You seem pretty excited about that — it's a big deal?"

  • "Why so happy?"

  • "Go on."



  • Rule of thumb: Ideas and feature requests should be understood, but not obeyed.

  • Rule of thumb: If you've mentioned your idea, people will try to protect your feelings.

  • Rule of thumb: The more you're talking, the worse you're doing.


In addition to ensuring that you aren't asking trivialities, you also need to look for the world-rocking scary questions you're shrinking from. The best way to find them is to run thought experiments, Imagine that the company has failed and ask why that happened. Then imagine it as a huge success and ask what had to be true to get there. Find ways to learn about those critical pieces.


There's no easy solution to making yourself face and ask these questions. I once heard the general life advice that, for unpleasant tasks, you should imagine what you would have someone else do if you were delegating it.

Then do that.


If you have a lot of product risk with your product you’ll have to start building product earlier and with less certainty than if you had pure market risk 


Prepare your list of 3

  • Always pre-plan the 3 most important things you want to learn from any given type of person.


Rule of thumb: If it feels like they're doing you a favour by talking to you, it's probably too formal.


Rule of thumb: If you don't know what happens next after a product or sales meeting, the meeting was pointless.


Time Commitment 

  • Clear next meeting with known goals

  • Sitting down to give feedback on wireframes

  • Using a trial themselves for a non-trivial period


Reputation Commitment 

  • Intro to peers or team

  • Intro to a decision maker (boss, spouse, lawyer)

  • Giving a public testimonial or case study



Financial Commitment

  •  Letter of intent (non-legal but gentlemanly agreement to purchase)

  • Pre-order

  • Deposit


Rule of thumb: It's not a real lead until you ve given them a concrete chance to reject you.


Rule of thumb: Keep having conversations until you stop hearing new stull.


Rule of thumb: If you aren't finding consistent problems and goals, you don't yet have a specific enough customer segment.


Signs you are going through the motion of a meeting:

  • You're talking more than they are

  • They are complimenting you or your idea

  • You told them about your idea and don't know what's happening next

  • You don't have notes

  • You haven't looked through your notes with your team

  • You got an unexpected answer and it didn't change your idea

  • You weren't scared of any of the questions you asked

  • You aren't sure which big question you're trying to answer by doing this
