71. Dave Morin

CEO and Cofounder, Path

Dave Morin is one reason why investors have poured millions of dollars into Path. In Path's latest round, it raised more than $30 million led by Redpoint Ventures. At the time, the firm said Morin was a huge draw. That's no surprise given that in March, many people said Facebook is afraid of Path. In September, Facebook CEO Mark Zuckerberg said he wants to work more closely with Morin.

But last year, Path had a big privacy misstep that cost it $800,000 in a settlement with the FTC. In addition, the app's growth stalled. After its relaunch in late 2011, Path signed up 1.5 million users in under three weeks. But it closed 2012 with about 5 million users—an agonizingly slow upwards climb.

Aside from the ups and downs at Path, Dave Morin has had other startup wins. Morin is an active angel investor and one of his portfolio companies, Behance, was acquired by Adobe for $150 million. Another startup he's invested in, Venmo, was acquired by Braintree last year for nearly $30 million.
