The Streaming Database for Real-Time Analytics
The simplicity of SQL queries, but with millisecond-level latency for real-time data. That is Materialize, the only true SQL streaming database for building internal tools, interactive dashboards, and customer-facing experiences.
We are not “disrupting” or changing the behaviors of the world’s population, but instead building something that works in a space where most products simply do not. Our work builds on top of Timely Dataflow and Differential Dataflow, both created by our co-founder Frank McSherry.
