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.
