Jeff Tangney

Jeff Tangney is the co-founder and CEO of Doximity (NYSE:DOCS), the LinkedIn-for-physicians network. His angel activity is thin in public records but logically clusters around digital health and healthcare software, especially companies that touch the physician workflow, communication, or commercial pharma channel where Doximity has expertise. AI focus not flagged. $100k-$250k at pre-seed and seed. San Francisco-based. Best fit: founders building physician-facing tools, clinician communication or workflow products, or pharma engagement plays where Doximity-style network effects are part of the story. Honest read: he is a sitting public-company CEO with a packed calendar and writes infrequent personal angel checks; treat him as a high-conviction, hard-to-reach investor rather than an active deployer. Entry path is LinkedIn (very low hit rate) or, better, a warm intro through Doximity executives, his Epocrates network (his prior company), or a fellow physician-founder. Anyone whose story is just hospital-facing IT, biotech, or consumer wellness should look elsewhere. If you do get the meeting, his bar will be on physician adoption and workflow fit, not on the deck or the TAM slide; show him how you actually get into the daily routine of a doctor.
