At an age when most college grads are happily taking orders on the bottommost corporate rung, CEOs Zach Sims and Nikhil Sethi (22 and 23 years-old, respectively) are leading fast growing businesses. Sims heads Codecademy, an interactive website that trains users in software programming, while Sethi runs Adaptly, a company that helps brands advertise across social media. With limited experience, these young entrepreneurs are successfully navigating the enormous challenges of building a business: raising capital, hiring and managing team members, closing partnerships and dealing with the press. In this panel, moderator J.J. Colao, a 25 year-old Forbes magazine reporter covering entrepreneurs, speaks with Sims and Sethi about their experiences running top-tier startups and their advice for the next crop of young founders.
