Last year, Forbes named him one of its “30 Under 30 Who Are Changing the World.” At the time, he had a high-level position focused on creator development at YouTube. Now the 28-year-old entrepreneur is starting fresh with his mobile media company, Victorious.

After graduating from the University of Pennsylvania in 2009 with a degree in creative writing, Chen was hired by Google and chose to work for its YouTube subsidiary. A big part of his job was helping creators—people who make the hundred hours of video that are uploaded to the site each minute—improve the size and engagement of their audiences.

“I didn’t work directly with the creators like a manager would, though I did become friends with many of them. Instead, I came up with ways to help creators as a whole, like starting a program where we’d give gift certificates to people who were doing well so they could buy better video equipment.”
