HealthKey

Executive Summary

HealthKey is a YC W25 pre-seed startup building AI-powered patient identification for clinical trial sites — a real, growing market where 80%+ of trials fail to hit enrollment targets and multiple data sources confirm a $187M direct TAM growing at 13.5% CAGR. The core product claim checks out: the website is live, EHR integration is described clearly, and YC acceptance is confirmed. However, this is a solo-founder company with ~10 employees, no disclosed co-founder or CTO, no public revenue metrics, and no confirmed clinical or regulatory expertise on the team — in a space that demands HIPAA compliance, FDA 21 CFR Part 11 awareness, and deep EHR integration work. The single biggest risk is not the market or the product concept; it's that a technically demanding, heavily regulated product is being built by one identified founder without the domain depth or team breadth that this category typically requires to win.
