SOSV for Life 

The friendships founders build at SOSV’s HAX and IndieBio startup programs last forever, and so do their ties to SOSV’s general partners and expert program staff, who long remain trusted advisors. SOSV continues helping founders raise investment, expand networks, and win press coverage long after the program ends.
