Nate Gross

Nate Gross is the co-founder of Doximity and now an active angel in early-stage digital health. He is one of the more accessible Doximity alumni for founders, with public engagement on Twitter and a track record of small but well-placed angel checks across health tech. His pattern centers on tech-enabled care delivery and healthcare software, especially anything that intersects with clinician workflow, physician network effects, or specialty care operations. AI focus not flagged. $100k-$250k at pre-seed and seed. San Francisco-based. Best fit: physician founders, clinician-tools and clinician-communication products, specialty care delivery models, and digital health companies that need a thoughtful early angel who has actually built a network business. Not a fit for biotech, devices, life sciences tools, or consumer wellness brands. Entry path is LinkedIn or Twitter, both of which are reasonably responsive, plus warm intros through Doximity, the Rock Health network, or current portfolio founders. He is helpful and operator-minded; expect questions about provider acquisition, retention, and the realistic shape of your go-to-market into health systems. Bring numbers, not narrative.
