Belsky told Garrett Camp the black-car app was a distraction

StumbleUpon founder Garrett Camp showed Belsky sketches of an app for summoning a black car in his New York apartment. Belsky told him it was a textbook distraction; fortunately Camp ignored the advice and it became Uber.

“Literally showed me these sketches of this product where it's about summoning a black car as opposed to having to dial for it. And, um, and I'm like, dude, you should be focused on your business. You just bought it back, right?”
