HealthKey
HealthKey is an AI-powered patient identification platform for clinical trial sites. It connects directly to a clinic's electronic health record system, reads every patient chart - including scanned and faxed PDFs - and scores each patient against a trial's eligibility criteria. Doctors get a ranked list of likely-qualifying candidates with the supporting evidence highlighted, replacing slow manual chart review. HealthKey charges success fees per enrolled patient, so sites pay only when it works. Founded in 2025 by Josh Sabol and backed by Y Combinator (W25), the company is based in Austin, Texas.

Founded in 2020 through the Texas Medical Center Biodesign program, Koda now reaches more than one million patients nationwide and pairs software with in-house clinical support to make sure care plans are understood and followed.
