Rapidly test and validate any startup idea with the 2-day Foundation Sprint (from the creators of the Design Sprint) | Jake Knapp & John Zeratsky (Character Capital)

In this episode of Lenny's Podcast, Jake Knapp and John Zeratsky discuss the Foundation Sprint, a framework designed to help founders and product teams refine and test their startup ideas. They explain how the Foundation Sprint, derived from the Design Sprint, helps teams align on their target customer, the problem they're solving, their differentiation from competitors, and how to quickly test their hypotheses with potential customers. They detail the three phases of the sprint: basics, differentiation, and approach, providing examples from companies like Latchit and Mellow. The conversation emphasizes the importance of deep thinking, team alignment, and rapid experimentation to increase the chances of achieving product-market fit, especially in the age of AI-driven development.
