Thatch is a health benefits company that helps businesses offer personalized health insurance through an ICHRA (Individual Coverage Health Reimbursement Arrangement) plus a Thatch Visa spend card. Its developer product, Thatch for Platforms, is a set of REST APIs and embeddable JavaScript components that let partners (payroll, HR, and SMB platforms) bring ICHRA benefits into their own applications: create employers, manage employees, run a hosted employer onboarding flow, track enrollments and members, model pay schedules, and pull monthly payroll deductions. The API is partner-gated, authenticates with a Bearer API key, and is documented at docs.thatch.com. Thatch is backed by a16z, General Catalyst, GV, Index Ventures, and Lux Capital.
