StumbleUpon CEO Reveals the Personality Type He Loves to Hire

By Rachel Sugar

Everybody wants to hire stars. But StumbleUpon CEO Mark Bartels isn't looking for people who shine alone — instead, he prioritizes candidates who are true collaborators.

Which isn't to dismiss the value of people who thrive alone. "You always want different types of people that you're working with, and individual contributors are great," Bartels tells Business Insider. "They're very productive, and they can have very high output." There's just one limitation: ultimately, they're only one person.
