Rill Data
Rill Data builds the fastest business intelligence tool for humans and AI agents. Founded in 2020 by Metamarkets veteran Michael Driscoll, Rill takes a BI-as-code approach: dashboards, metrics, and business logic are defined in SQL and YAML, versioned in Git, and powered by embedded OLAP engines (DuckDB in Rill Developer, ClickHouse and Apache Druid in Rill Cloud). The result is sub-second, operational dashboards that teams actually use - processing more than 100 billion daily events for customers in programmatic advertising, media, and fintech.
Michael Driscoll
Michael Driscoll is the co-founder and CEO of Rill Data, a company building fast, operational business intelligence dashboards on top of an embedded analytics engine. He previously co-founded Metamarkets, the ad-analytics firm whose internal database became the open-source project Apache Druid before Snap acquired the company in 2017. A bioinformatician turned serial entrepreneur, Driscoll began his career as a software engineer on the Human Genome Project, holds a PhD in Bioinformatics from Boston University and an AB from Harvard, and has spent three decades arguing that metrics, not tables or dashboards, are the real interface between data teams and the businesses they serve.
