Sam Lambert
Sam Lambert is the CEO and President of PlanetScale, the database company built on Vitess, the MySQL scaling technology that once powered YouTube. A database engineer by trade, he started as GitHub's first DBA in 2013 and spent roughly eight years there, rising to VP of Engineering leading a 350-person infrastructure and platform organization through the era GitHub scaled to tens of millions of users. After a short stint at Facebook working on internet-scale video infrastructure, he joined PlanetScale as an investor and advisor, became Chief Product Officer, and was named CEO in July 2021. He is known for a product philosophy centered on databases that 'just work' and never go down, a bias toward taste and craft, and blunt views on leadership.

It helps engineering leaders see where their teams spend time, tie that work to company strategy, automate R&D cost capitalization, and measure the real ROI of tools like GitHub Copilot. Founded by veterans of Endeca, Jellyfish has raised roughly $117M and serves hundreds of enterprises including Mastercard, Priceline, and PagerDuty.
