Jeffrey Hausfeld

Jeffrey Hausfeld is a physician (BioFactura affiliation), DC-based solo angel, and active healthcare entrepreneur writing $25k-$100k checks at pre-seed and seed in biotech and medical devices, with no AI flag. The MD operating background and BioFactura affiliation suggest practical pattern recognition on biologics, biosimilars, and clinical-stage biotech operations. Founders building biotech with clinical-stage ambition, medical devices with clear regulatory pathways, or companies where his physician-operator and BioFactura context adds meaningful clinical and regulatory value are the natural fit. He is the wrong audience for digital health software, consumer wellness, AI-only plays, or anything outside the clinical-biotech-and-device stack. The small check size positions him as a high-signal physician-operator participant rather than a lead, but his clinical credibility and DC-area network (NIH, FDA proximity) bring real value beyond capital. Outreach via LinkedIn is the primary channel; warm introductions through the DC biotech community, BioFactura networks, or physician-investor groups (Society of Physician Entrepreneurs, where he has been active) materially outperform cold notes. Without a published thesis, founders should rely on his BioFactura operating context as the primary signal of fit. Best treated as a clinical-credibility small angel for the right biotech or device founder with FDA or NIH-relevant strategy.
