Retrace is a San Francisco AI company rebuilding the plumbing of dental insurance. Founded in 2016 by dentist-engineer Dr. Ali Sadat, it operates what it calls the first natively-built AI healthcare clearinghouse - a network that reads X-rays and clinical records, compares proposed procedures against millions of adjudicated cases, and lets payers, providers and patients see coverage, cost and payout in real time so claims settle in seconds instead of weeks. Backed by Intel Capital and SoftBank, Retrace has raised roughly $18 million to automate the paperwork that sits between a dentist's chair and an insurer's check.
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.
