SOSV
HAX / IndieBio
Independent editorial profile; DNA Future is not affiliated with or endorsed by this institution unless expressly stated. Two separate SOSV programs: HAX for hard tech and SOSV SF, the birthplace of IndieBio, for life sciences and deep tech.
THE INSTITUTION
What is SOSV?
SOSV is a global venture capital firm founded by Sean O’Sullivan.
It invests in deep tech, hardware, climate, health and biology through specialized programs and locations.
Sean O'Sullivan founded SOSV in 1995. The firm later built specialized programs and facilities for hardware, biology, climate and health companies.
SOSV reports about $1.5 billion in assets under management, a $306 million fifth flagship fund and roughly 800 active portfolio companies.
HAX and IndieBio/SOSV SF have supported companies across hard tech, biology, climate and health; they are separate programs with separate review teams.
Applicants should use HAX for hard tech and SOSV SF for life sciences and deep tech rather than treating them as one program. SOSV's central application page is the stable route for both.
