Stack Health

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.

Stack Health is profiled on the APIs.io network. Tagged areas include Company, Health Insurance, Healthcare, Fintech, and Insurance.

Stack Health’s developer surface includes signup flow and 10 more developer resources.
