Zack Kanter
Zack Kanter is the founder and CEO of Stedi, an API-first, cloud-native healthcare clearinghouse that routes eligibility checks, claims, and electronic payments between providers and insurers. He started his first company at 16, building a bootstrapped auto-parts wholesaler (Proforged) that he ran for roughly 13 years before selling it to Huron Capital. He then spent years wrestling with electronic data interchange (EDI), the arcane plumbing of business-to-business transactions, rewriting Stedi's codebase about eight times before finding extraordinary traction in healthcare. Along the way he became widely read for essays like 'Why Amazon is eating the world.' In March 2026 Stedi raised a $50M Series C led by Addition, bringing total funding to about $142M.
Retrace
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
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.
