Life Science Angels

Founded in Silicon Valley, Life Science Angels is an elite angel investment group operating out of Sunnyvale that funds rigorous early-stage medical device, biotechnology, and diagnostic innovations. The network draws on a deep bench of physician, scientist, and operator members who underwrite scientific risk before writing checks, pursuing companies whose data packages and clinical paths can withstand expert scrutiny. Their portfolio bias skews toward medtech and diagnostics where regulatory clarity and clinical utility can be evidenced early, complemented by therapeutics opportunities that match member expertise.

The group concentrates on Pre-Seed and Seed rounds, deploying $250k to $1M per opportunity, typically alongside other angel groups or institutional seed funds. Geographic focus is firmly North America, with strong density in the San Francisco Bay Area and California’s broader life sciences corridor, though they occasionally look at out-of-region deals where members have direct domain ties. Engagement runs through screening committees rather than a single partner gatekeeper.

Founders should arrive with clean preclinical or clinical data, a defensible regulatory strategy, and a milestone-driven use of proceeds. Applications go through formal screening, so a tight executive summary and a credible scientific advisory board matter more than narrative. Expect substantive technical due diligence from members and be ready for follow-on syndication conversations rather than a one-meeting close.
