Which book has had the strongest effect on how you make products? And why?

For me, it has been - Getting Real from 37signals, the makers of Basecamp It reminded me that you need to focus on things that really matters

To be honest, I need to say "Rich Dad Poor Dad", while not exactly a business book. It's main premise is to not let yourself work for money but make money work for you. This message has stuck with me for years and has inspired me to dedicate myself to entrepreneurship, to hopefully make money work for me :)

"The Design Of Everyday Things" by Don Norman. It reminds me of how important it is to remember that your users are humans and they will make mistakes if you design badly.

Losing My Virginity, Richard Branson. I read it at the age of 14, and I realized that I definitely don’t want to work for hire. At the age of 15, I launched my first startup. A very simple but very motivating book.

To be honest many books left an impression on me. Those that I found to be most interesting are: Paypal Wars by Eric M. Jackson Think and Grow Rich, Napoleon Hill Average Is Over: Powering America Beyond the Age of the Great Stagnation by Tyler Cowen Data Smart Using Data Science to Transform Information into Insight by John W. Foreman (

A popular book in the field of product design and development is "The Lean Startup" by Eric Ries. It has been influential because it promotes a scientific approach to creating and managing startups, emphasizing iterative development, validated learning, and continuous improvement.

“Obviously Awesome” by April Dunford I reviewed everything I had been thinking about positioning. It is a big helper these days for me. “Think of your product as a fishing net”. “Startup. Shift up. Screwup” by Jurgen Appelo Modern practices on company building based on experience of various startup founders that Jurgen had interviews with. A bunch of new concepts like Innovation Vortex or business model as a family member.

For me was Creativity inc. Amazing book from founder of Pixar. Also has some interesting insights into Steve Jobs :)

Build: An Unorthodox Guide to Making Things Worth Making, by Tony Fadell. Amazing lessons all the way from building a company, team and product.

There are two books I would absolutely recommend from a product management point of view. "Inspired" from Marty Cagan and "Continuous Discovery Habits" from Teresa Torres. Ideally start with "Inspired" and then continue with "Continuous Discovery Habits". Why? IMHO the single most important thing you can learn from these book is how to interview users and how to derive guidance from these interviews (read: how to make insights actionable). We applied the techniques at our new startup. We ran 75+ user interviews so far to really understand our users, their problems and desires. We are using a template to structure the interview and the notes. You will end-up with tons of opportunities. It is totally amazing to see the patterns emerge from the interviews. Feed these opportunities in ChatGPT-4 and it will deduplicate and count them for you. This gives you a super nice ranking of what people actually need. It will help you to put the right stuff on your website and to build the right features into your product. You can of course also use these insights in your sales talks to break the ice and to demonstrate your domain knowledge.

100M Offers by Alex Hormozi. It tweaked the way I look at markets.
