Stack Healthcare (stackhealthcare.com) is a health-insurance fintech offering affordable, flexible coverage for small businesses and their teams. Operating as a technology company rather than a bank, Stack acts as a HIPAA Business Associate to employer-sponsored health plans, processing Protected Health Information for enrollment and benefits administration, and partners with Stripe for payments and Celtic Bank for issuing commercial cards. The company was surfaced as a portfolio company of 8vc and added to the API Evangelist network. As of this enrichment pass Stack publishes no public API, developer portal, SDK, or documentation surface — the product is a waitlist-gated web application — so this profile captures the identity, security, and compliance posture that is publicly verifiable.
