How a B-School Networking Problem Became a $20 Million Opportunity Bump Technologies co-founder David Lieb went to business school to make contacts. He left to build a new way to share them.

Daydreaming in class is often a habit students come to regret on test day--that is, unless that dream turns into a real company.

That's exactly what happened when David Lieb, CEO and co-founder of Bump Technologies, entered the University of Chicago's MBA program in the fall of 2008.

While attending an accounting class, Lieb's mind drifted from the lecture to imagining an easy, efficient way to share contact information. "Business school is all about meeting people and networking, and the first week, I found myself entering in phone number after phone number, and name after name," Lieb says.
