I’ve noticed a recurring mistake that most early-stage startup founders tend to make. My experience working with over a dozen startups has consistently highlighted this issue. This is mostly intended for founders and early teams. It will also be useful to those working on something new. I’ve seen positive results in my work with early products, and some of the ideas and discussions have been helpful to the founders I’ve worked with. That’s why I decided to write it all down and share it. The text came out quite lengthy, but hopefully, you’ll find something useful in it.

  • Frameworks and tips for using mental models: practical advice for founders on how to incorporate mental models into their work, even without a designer on the team.
