Kate Greer is a woman who appears to have very expensive taste in men. For four years, she dated Jack Dorsey, who founded Twitter. When they split up, she moved on to Peter Fenton - one of Twitter's most prominent investors. That must have stung Dorsey!
While she dates technology guys, her own business interests are strictly offline. She has a popcorn company called Cheerie Lane, and makes enough money that way not to have to rely on Henton's fortune.
