Spencer Kimball
Spencer Kimball is the co-founder and CEO of Cockroach Labs, the company behind CockroachDB, a distributed SQL database built to survive almost anything you throw at it. Long before databases, he co-wrote GIMP as a Berkeley class project in 1995, spent roughly a decade as an engineer at Google working on its file-system guts, and built a photo startup that Square acquired. He named his database after the one creature famous for being nearly impossible to kill - which turned out to be the perfect pitch.
Dylan Cui
Dylan Cui is a co-founder of PingCAP, the company behind TiDB - one of the world's most widely adopted open-source distributed SQL databases. A software engineer by trade, Dylan co-built TiDB from scratch starting in 2015 after experiencing firsthand the pain of database scaling at scale while working at Wandoujia. PingCAP has raised over $341 million and TiDB has more than 33,000 GitHub stars, serving thousands of enterprises globally across fintech, gaming, and e-commerce.
Max Liu

He co-founded PingCAP in 2015 after stints at JD.com and Wandou Labs, solving the database scaling crisis at hyperscale. Under his leadership, PingCAP raised $341.6M in total funding including a $270M Series D, and TiDB now serves customers including Pinterest, Plaid, Bolt, and Atlassian. In 2025, Liu was named one of The Top 50 Software CEOs of 2024 by The Software Report.
Matt Cain
Matt Cain is a technology executive who served as Chair, President, and CEO of Couchbase from April 2017 through September 2025, guiding the company from a growth-stage NoSQL database startup through a 2021 NASDAQ IPO and ultimately a $1.5 billion acquisition by Haveli Investments. With an engineering degree from Northwestern and an MBA from Stanford, Cain built his career across a decade at Cisco Systems, senior roles at Symantec, and the presidency of Veritas Technologies' worldwide field operations before joining Couchbase. Under his leadership, Couchbase expanded from pure NoSQL into a multi-model developer data platform powering AI-enabled applications for global enterprises.
