Aspect Ventures, an early-stage, five-year-old, San Francisco-based venture firm founded five years ago very notably by two veteran VCs who happen to be women, is splitting up. Cofounders Jennifer Fonstad, formerly of DFJ, and Theresia Gouw, formerly of Accel, are launching separate firms, a source confirms. The WSJ reported the news earlier today. Fonstad tells the outlet that the split owes to “different leadership styles and different ways of operating at the portfolio level.” Going forward, she plans to operate under the brand Owl Capital and to invest in growth deals, including in enterprise software, which has been a major focus area for Aspect, with occasional exceptions, including the newly public consignment business TheRealReal and a direct-to-consumer jewelry brand called Baublebar. Gouw, who is appearing in several weeks at our TechCrunch Disrupt event to talk about industry trends, declined to comment.
