Judy Thelen and Eliot Frost met at their first job out of college. They’ve done everything together since, including going to business school, getting married and, nearly four years ago, launching Beli, the increasingly popular restaurant rating and list-keeping app.

“We’re at over 58 million ratings,” Thelen said. Users log on and rate restaurants all over the world. Thelen and Frost don’t track how many hours users spend engaging with their product, “because if you’re spending a lot of time in the app, you’re not going out and doing things in the real world,” she added. “Beli is supposed to help you eat.”
