Good news for Tracy Dinunzio: her P2P clothing site Tradesy just closed a $13 million round from Kleiner Perkins and Richard Branson. This financial support is a far cry from the days of founding Tradesy: in 2012, Dinunzio launched Tradesy by putting her apartment’s guest room on Airbnb, selling her car and borrowing $5,000 from her parents three times. Then, without a technical background, she set out to build the platform herself.
