Having 100% of something vs having 93% of something with access to a great network, a demo day for best investors, great mentors, resources for HW startups, Azure grants for SW startups (worth $500k) etc etc. Some time ago, PG published an email exchange between himself and Fred Wilson, where PG was really pushing USV to invest in AirBnB, what a service for both sides. How much would you pay for it? IMO 7% for 120k is quite cheap, especially if you're in early stage.
