Character is a venture capital fund built around the Design Sprint method, co-founded by Jake Knapp and John Zeratsky, the creators of the Design Sprint and co-authors of Sprint, Click, and Make Time, who previously ran over 100 sprints at GV with companies like Slack, Flatiron Health, and Uber. The firm treats founders as customers, focuses on frontier applications of software like AI in science and medicine, runs a small accelerator called Labs that caps cohorts at 15 companies to keep direct access to partners, and openly teaches its methods through books and workshops rather than treating them as secret sauce.
