most interested in

When everyone else says "too early," it's often just right for IndieBio. We like huge, daring things. We like risk, and just minimize the cost of risk.

not interested in

We deploy 80% of our capital after the Accelerator stage -- but we only invest in companies that have been through an SOSV accelerator program at some point in time. So ... we don't come into companies at later rounds. We start Pre-Seed and continue investing through Series B or C.
