Yin Wu has co-founded several companies since graduating from Stanford in 2011, including a computer vision company called Double Labs that sold to Microsoft, where she stayed on for a couple of years as a software engineer. In fact, it was only after that sale she she says she “actually understood all of the nuances with a company’s cap table.” Her newest company, Pulley, a 14-month-old, Mountain View, Ca.-based maker of cap table management software aims to solve that same problem and has so far raised $10 million toward that end led by the payments company Stripe, with participation from Caffeinated Capital, General Catalyst, 8VC and numerous angel investors. Wu is going up against some pretty powerful competition.
