Fifteen years ago I created the Design Sprint at Google. After hundreds of sprints with teams like Gmail, Chrome, Slack, Uber, and Flatiron Health, I introduced this method to the world with the bestselling book Sprint. Since then, the Design Sprint has been adopted by Airbnb, Amazon, LEGO, MIT, Mercedes-Benz, OpenAI, Harvard Business School, the University of Oxford, and many other organizations.

Three years ago, for the first time since Sprint, I created a major new sprint method: the Foundation Sprint. Based on my work with early-stage startups at Character Capital, the Foundation Sprint takes all of my best techniques for starting big projects and packages it into a fun, simple, and effective two-day sprint format.

On the morning of day one, you’ll define the basics of your project, then, in the afternoon, you’ll craft differentiation to help you stand out from the competition. On day two, you’ll evaluate multiple options and choose an approach to your project. By the end, you’ll have a Founding Hypothesis: a clear statement of what you believe that can be proved (or disproved) with Design Sprints.
