Chris Severn
Chris Severn is the co-founder and CEO of Turquoise Health, a San Diego company building software to make healthcare pricing transparent and to simplify the way hospitals and insurers contract and pay each other. After a decade modeling hospital managed-care contracts and running machine learning for payment integrity, he started Turquoise in 2020 with engineer Adam Geitgey, pivoting into federal price-transparency rules just as they took effect. The company has aggregated price data from thousands of hospitals and, in March 2026, raised a $40 million Series C led by Oak HC/FT to become what Severn calls the operating system for healthcare contracts and payments. He also teaches improv comedy and has testified before Congress on price transparency.
Dick Costolo
Dick Costolo is a co-founder and General Partner at 01 Advisors, a $920M venture firm he built with former Twitter COO Adam Bain. Before that, he was the CEO of Twitter from 2010 to 2015 - the longest-tenured and most financially productive CEO in the company's history, growing revenue from zero to $1.5 billion and leading its 2013 IPO. He started his career as an improv comedian at Chicago's Second City (Steve Carell was in his cohort), built and sold three startups including FeedBurner to Google for ~$100M, and remains one of the most candid, self-deprecating, and operationally sharp executives in Silicon Valley.
