James Hawkins
James Hawkins is the co-founder and co-CEO of PostHog, the open-source product analytics platform built for engineers. He pivoted five times inside Y Combinator's W20 batch before landing on PostHog, then turned a Hacker News launch and a single tweet into a developer cult following and a $1.4 billion valuation. A former marketing operator and self-described 'very bad developer,' Hawkins runs PostHog on radical transparency, tiny autonomous teams, and a refusal to be boring.
Matthew Arbesfeld
Matthew Arbesfeld is the CEO and co-founder of LogRocket, the Boston-based frontend monitoring and product analytics company he built with his lifelong best friend Ben Edelstein. The two met as one-month-old infants on a parental playdate and have been building software together ever since. A Thiel Fellow who dropped out of MIT in 2015, Arbesfeld first launched a developer deployment tool called AppHub before pivoting to LogRocket, the 'DVR for bugs' that lets engineering teams replay exactly what users did before something broke. LogRocket has raised about $55 million total, monitors billions of user sessions, and in 2026 launched Ask Galileo, an AI layer that answers plain-English questions about user experience.
