Materialize

Materialize is a New York-based data infrastructure company that builds a streaming SQL database. It continuously ingests data from operational systems, incrementally maintains the results of complex SQL queries as always-fresh materialized views, and serves them with low latency. Built on the open-source Timely Dataflow and Differential Dataflow engines and written in Rust, Materialize looks and behaves like Postgres, letting engineers use standard SQL to power real-time analytics, automation, personalization, fraud detection, and - more recently - a live context layer for AI agents and applications.
