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.
Brett Berson
Brett Berson is a Partner at First Round Capital, the early-stage venture firm behind Uber, Square, and Notion. Starting as a college intern in 2008, he spent over 15 years rising through the ranks to co-lead the firm. He is the architect behind the First Round Review (the firm's widely-read editorial publication), the In Depth podcast, and Angel Track — a program that trains operators to become better angel investors. Named to Forbes' 30 Under 30 in Venture Capital in 2015, Berson holds NYU degrees in economics and film, and credits studying filmmaking with teaching him to notice the thousands of micro-decisions that compound into company-defining outcomes. His key portfolio bets include Clay, Persona, and Stedi.
