The Mom Test: What Successful Founders Know About Customer Validation
The Mom Test: What Successful Founders Know About Customer Validation
The Mom Test Book Cover
One of the most frequently recommended books in the indie hacker and startup community is Rob Fitzpatrick's "The Mom Test: How to Talk to Customers & Learn if Your Business is a Good Idea When Everyone is Lying to You".
But what makes this slim volume so valuable? We've compiled notes and insights from several experienced founders who have applied these principles in their own businesses. Their perspectives might help you understand why this book is essential reading for anyone building products or services.
Why "The Mom Test" Matters
The core concept is deceptively simple: when you ask your mom (or friends and family) if your business idea is good, they're inclined to be supportive rather than honest. This creates a dangerous feedback loop of false positives that can lead entrepreneurs to invest time and money into ideas that haven't been properly validated.
Instead of getting validating opinions about your solution, the book teaches how to extract factual information about your customers' problems.
Key Insights from Experienced Founders

Gaël Thomas
Gaël highlights three fundamental teachings from the book:
Focus on problems, not solutions: "Conversations about your business should focus on understanding real customer problems through observations and inquiries into their past experiences, avoiding asking for opinions on your idea which often leads to misleading feedback."
Ask probing questions: "Effective customer engagement involves asking probing questions that uncover true needs and evaluating the customer's commitment, rather than gathering superficial or optimistic feedback."
Actions speak louder than words: "The ultimate validation of a business idea comes from market response and customer actions, not from the opinions or future promises of potential customers."
Gaël's detailed notes also emphasize that:
"Bad conversations with customers aren't just useless; they give you a false positive that causes you to over-invest your cash, time, and energy"
"Only the market can tell if your idea is good; everything else is just an opinion"
"People stop lying when you ask them for money"

Arvid Kahl
As the co-founder of FeedbackPanda (which was successfully acquired), Arvid brings practical experience to his interpretation of the book:
Look for commitment, not compliments: "Money on the table is the only meaningful metric. Only if people want to act on their words do you know that the conversation was fruitful."
Focus on specific customer segments: "Be specific in who you talk to. Aiming too big will dilute your data and make it hard to infer any meaningful results."
Ask about problems, not your product: "Ask about what people do to solve their problems right now. You want to learn things, not sell your product."
Arvid shares how these principles impacted his business:
"Having read The Mom Test allowed me to always ask the right questions and just listening to the customer. Often, that would lead to revelations about how they were using the product that we had never expected or intended. The value of this information was insane: it allowed us to significantly improve our onboarding and self-help materials and our trail-to-subscriber numbers skyrocketed."

Serial entrepreneur Marc Lou distills his takeaways into concise, actionable points:
"To ask valuable questions to potential customers: talk about their lives, not your product + talk about past, not future"
"People won't pay for something they aren't already trying to solve"
"Dig into emotions, ask why"
"The less you talk, the better"
"Look for negative answers/feedback"
Marc also notes that "your idea/product doesn't need to enter the conversation to learn about the market/problem" - a counterintuitive but powerful approach to customer research.
Common Themes and Practical Applications
Across all three founders' notes, several common themes emerge:
Actions over words: Real validation comes from commitment (especially financial), not from positive feedback.
Focus on problems, not solutions: Understanding your customers' actual problems provides more valuable insight than their opinions about your solution.
Be specific with your target market: If you can't find consistent problems and goals, you need to niche down further.
Talk less, listen more: The art of good customer interviews is in asking the right questions and then truly listening to the answers.
Seek the truth, even when uncomfortable: As Gaël notes, "you should be terrified of at least one of the questions you're asking in every conversation."
How to Implement The Mom Test in Your Business
Based on these founders' experiences, here are practical ways to implement The Mom Test principles:
Prepare your top 3 questions before any customer conversation
Keep conversations casual and brief - learning works better in quick chats than formal meetings
Look for commitment or advancement after each conversation
Take notes during or immediately after speaking with customers
Continue conversations until you stop hearing new insights
Conclusion
"The Mom Test" offers a pragmatic framework for validating business ideas through effective customer conversations. By learning to ask the right questions and interpreting responses correctly, founders can avoid the pitfalls of false validation and build products that genuinely address customer needs.
As Arvid Kahl succinctly puts it: "Good things can come from being genuinely interested in the people you work with. The Mom Test will show you how to avoid wasting your customers' and your own time and how to get meaningful feedback quickly."
Whether you're just starting out or looking to refine an existing product, the principles in this book provide a valuable compass for navigating the complex landscape of customer discovery and validation.

Cal Newport's Deep Work: How Successful Founders Achieve Focused Productivity
4/8/2025
Deep Work: How Indie Makers Find Focus in a Distracted World
In a world where distractions are endless and attention spans are shrinking, Cal Newport's "Deep Work: Rules for Focused Success in a Distracted World" has become essential reading for indie makers and entrepreneurs seeking to produce meaningful work. This book stands out in our community, appearing in 10 different reading collections from notable creators.
What is Deep Work?
As Marc Lou (@marc_louvion) succinctly notes in his detailed breakdown: "High quality work = time spent X intensity. There's no point working longer without focusing."
This equation captures the essence of Newport's thesis: truly valuable work requires concentrated effort free from distractions. It's not just about putting in hours—it's about the quality of those hours.
Key Takeaways from the Community
Arvid Kahl's Simple Recommendation
Arvid Kahl (@arvidkahl), successful bootstrapper and author, keeps his endorsement straightforward: "Read this if you want to focus more on high-quality work and be less distracted."
The brevity of his note speaks volumes—sometimes the most powerful concepts require little explanation. For Arvid and many other successful indie makers, developing a deep work practice is non-negotiable.
Marc Lou's Detailed Insights
Marc Lou extracts several actionable insights that particularly resonate with creators and entrepreneurs:
The Myth of Productivity vs. Being Busy
"People use show they're busy to pretend they're productive"
"Your world is the outcome of what you pay attention to"
"Focus on a single deep task to avoid drifting towards shallow/shitty events"
The Reality of Inspiration and Ideas
"Inspiration doesn't struck randomly"
"It arises from constraints and execution"
The Importance of Downtime
"Taking time off is crucial" for three reasons:
"Good ideas come"
"The brain background process fixes stuff"
"The brain rests for better work later"
Practical Implementation Strategies
"Have an end-work routine: Schedule unfinished tasks for another day"
"Concentration is a muscle. It improves with practice"
"Have a no-internet baseline, and schedule a timeframe to go online"
"Schedule every hour of your day to avoid being drawn into shallow activities"
Who's Reading Deep Work?
The book appears in collections from diverse makers:
It's part of Yuya Uzu's "Indie Hacking" collection
Found in personal collections from Arvid Kahl, Marc Lou, Melvyn, Paulo Lima, and Dany
Interestingly, it appears in Eugene Galaxy's collection "How do I live until 100?" suggesting its principles extend beyond just work productivity
The Anti-Distraction Manifesto for Makers
What makes "Deep Work" particularly relevant for indie makers and entrepreneurs?
In a world of constant notifications, social media updates, and the pressure to always be "on," Newport's philosophy offers a counterintuitive approach: disconnect more to produce more.
As Marc notes: "Our brain has a background task management that works when we don't. The more we do, the more distracted we are. Do 1 thing well."
This message resonates powerfully with indie makers who must wear multiple hats while still producing their core work. The ability to focus deeply might be the most important skill for solo creators and small teams.
Implementing Deep Work in Your Life
The most valuable aspect of Newport's book is its practicality. Based on the notes from our community members, here are actionable steps to incorporate deep work into your routine:
Create distraction-free windows for your most important work
Schedule your entire day to prevent drifting into shallow activities
Limit internet usage to scheduled periods
Develop an end-of-day routine to help your brain disconnect
Practice concentration like a muscle, gradually building strength
Be selective about tools and commitments - every addition comes with a cost
How Entrepreneurs Use Cialdini's Influence: Marketing Psychology Notes from Indie Makers
4/8/2025
The Remarkable Influence of "Influence": Notes from the IndiesReadIt Community
"Influence: The Psychology of Persuasion" by Robert B. Cialdini has become one of the most referenced books among indie makers and entrepreneurs in our community. The principles outlined in this classic psychology text continue to shape how founders approach marketing, product design, and customer relationships.
Why "Influence" Matters to Makers
Despite being published decades ago, Cialdini's six principles of persuasion remain relevant across digital products and services today. The book appears in 10 different reading collections from community members including notable founders like Marc Lou, Noah Kagan, and others.
Key Insights from Community Notes
Marc Lou's Concise Takeaways
Marc Lou (@marc_louvion) highlighted these fundamental principles:
"Expensive = good" - Our brains use price as a shortcut for quality assessment
Using comparison to create value perception (showing a $10 item next to a $5 item)
The importance of appearing as an expert
Reciprocity as a powerful motivator - "I give, you give back"
Starting with a larger request before making a smaller one
Including reasons when making requests
Commitment and consistency in social image
Dany's Entrepreneur-Focused Framework
Dany (@MajorBaguette) organized the book's concepts into a comprehensive framework for entrepreneurs:
Contrast Principle
Sell expensive items before cheaper ones
Set good prices rather than constant discounts
Reciprocity Principle
People feel indebted when given something
Use free samples or personalized gifts
Problem-solving creates higher satisfaction than prevention
Social Proof Principle
Popular products sell better (95% of people are followers)
Use social proof carefully to guide uncertain customers
Authority, Scarcity & Consistency
Position yourself as an authority
Limited availability increases desirability
Small commitments lead to larger ones
Dany summarizes the three key teachings as:
"Reciprocity: Offer value to create a sense of obligation"
"Social Proof: Show others' success to guide uncertain buyers"
"Stay Ethical: Use influence techniques responsibly and honestly"
Community Adoption
It's notable that "Influence" appears in collections from makers across different specialties:
Hunter Yeagley includes it in "Maker's Must-Reads"
It appears in personal collections from Gaël Thomas, Igor Krasnik, John Rush, and Paulo Lima
Noah Kagan, known for AppSumo and other ventures, also features it
Applying These Principles
What makes "Influence" particularly valuable is how applicable its principles are across different contexts. Whether you're designing onboarding flows, pricing strategies, or marketing materials, understanding the psychology of persuasion gives you powerful tools.
However, as Dany notes in their third key teaching, these techniques should be used ethically. The goal isn't manipulation but understanding how to effectively communicate value and overcome natural human hesitation.
