John Dayton

John Dayton is a physician (Salt Lake City-based) and solo angel writing $25k-$100k checks at pre-seed and seed in medical devices and digital health, with no AI flag. The MD operating background and Mountain West geography position him as a clinician-and-physician-investor angel with focus on the device-and-digital-health intersection. Founders building Mountain West-based medical devices, digital health platforms targeting clinicians or emergency medicine (his clinical specialty), or companies where his physician-investor credibility adds meaningful clinical value are the natural fit. He is the wrong audience for biotech, consumer wellness without a clinical angle, B2B healthcare software outside the physician-facing space, AI-heavy plays, or anything outside his clinical-specialist orbit. The small check size positions him as a clinical-credibility participant in a party round rather than a meaningful capital source. Outreach via LinkedIn is the primary channel; warm introductions through the Salt Lake City and Mountain West healthcare community, the emergency medicine physician-investor community (he is publicly active on this), or fellow physician-angel networks materially help. Without a website, Twitter, Crunchbase, or published thesis, founders should rely on his LinkedIn activity and clinical specialty context as the primary intelligence source. Best treated as a clinical-credibility small angel for the right clinician-facing or device founder with Mountain West relevance.
