what is sandbox?

Sandbox is the university program you wish you had. It's a year-long, full-time, software startup incubator that replaces nearly a year of college credit.

Sandbox founders don't just come up with cool ideas, they launch real companies. Nine Sandbox companies have been venture-backed at a combined $95M valuation with 5 accepted to Y Combinator. Founders who don't continue with their startups land jobs with starting salaries averaging 25% more than their peers. 1
