Hello Jan,

Subsurface, proudly presented by Dremio, is back—and bigger than ever.
This year, we’re hitting the road to bring together the brightest minds in open data lakehouse innovation across five major cities.

Subsurface is the go-to destination for data engineers, architects, and open source contributors to explore the latest advancements in the modern data stack—with real-world stories from the teams building and scaling it.

Want to speak at Subsurface?
We’re looking for practitioners and builders to share their journeys—successes, learnings, and everything in between. Whether you’ve tackled big performance wins with Apache Iceberg, wrangled complexity with Arrow, or modernized your stack with Dremio, we want to hear from you.

Call for speakers closes Friday, August 15 at 11:59pm PT.
