Jake Knapp and John Zeratsky are the co-creators of the Design Sprint (the famous five-day product innovation process) and authors of the bestselling book Sprint. After decades of working with over 300 startups in the earliest stages, they discovered that most startups fail not because they can’t build, but because they build the wrong thing. The very beginning of a startup is your highest-leverage moment, and most teams waste months or years by skipping a few critical early questions. Jake and John developed the Foundation Sprint to help startups validate ideas and compress months of work into just two days.

What you’ll learn:

1. The step-by-step Foundation Sprint process that compresses three or four months of validation into two days—including templates you can use immediately

2. Why differentiation is the #1 predictor of startup success (with the 2x2 framework that you can use with your team)

3. The three fundamental questions every founder should answer before writing a line of code

4. The “note and vote” technique that eliminates groupthink and gets honest answers from your colleagues

5. The seven “magic lenses” for choosing between multiple product ideas

6. The biggest mistake engineers make when building with AI tools

7. The paradox of speed: why “building nothing first” can get you to product-market fit faster
