Chalk provides a real-time data platform for ML and LLM inference that compiles Python feature definitions into high-performance Rust/C++ pipelines, unifying feature store, vector storage, monitoring, and experiment branches.
About Chalk Chalk is building the data platform that powers the future of machine learning applications. We tear down complexity, latency, and scale barriers that have traditionally constrained ML capabilities. Our platform combines Rust-speed performance with elegant tools that developers love to use. Leading companies depend on Chalk for everything from stopping fraudulent credit card swipes, verifying identities, and maximizing clean energy capture. We've recently raised a $50 million Series A https://www.reuters.com/business/databricks-competitor-chalk-raises-50-million-series-2025-05-28/, led by Felicis.
