About
Chalk is a data platform purpose-built for machine learning and generative AI applications. Founded in 2022 by Marc Freed-Finnegan, Elliot Marx, and Andrew Moreland — veterans of Affirm, Palantir, Google, and Stripe — Chalk provides real-time data pipelines, feature computation, and caching infrastructure that deploys directly into a customer's own cloud. The platform addresses the gap between offline model training and real-time inference by enabling developers to define features in Python once and serve them consistently across training, batch scoring, and online prediction workloads. Chalk supports integrations with PostgreSQL, Snowflake, AWS, Google Cloud, Databricks, and Apache Airflow. Customers include Ramp, Whatnot, Socure, and Turo. In May 2025, Chalk raised a $50M Series A at a $500M valuation led by Felicis Ventures.
