Stedi

Stedi is an API-first, cloud-native healthcare clearinghouse that sits between providers and payers to move essential transactions - eligibility checks, claims, claim status, and electronic remittances - as programmable API calls instead of legacy batch files. Founded in 2017 by Zack Kanter, who came to EDI through an auto-parts business, Stedi rebuilt clearinghouse plumbing from scratch for the API and AI-agent era. It connects to thousands of U.S. payers, processes more than a billion transactions annually, and has raised $142 million from investors including Stripe, Addition, USV, and First Round.
