Chalk
19 open jobsGeneral information
Chalk runs a real-time AI data platform that gives agents and machine learning models the context and infrastructure they need to work. Its Feature Store holds the data models draw on, its Real-Time Serving Engine delivers that data as it happens, and its Training Data Management system organizes the data used to train models. The company is based in San Francisco, with a second office in New York.
Marc Freed-Finnegan, Elliot Marx and Andy Moreland founded Chalk. The company raised $50 million in a Series A round in May 2025, a sign of the resources behind a team still building out its core platform.1
