Machine learning infrastructure is painful
Chalk makes it simple for data teams to focus on building the unique products and models that make their businesses thrive.
Chalk has become a critical component of our Risk Intelligence Platform. It expanded Ramp's capabilities with online machine learning and enabled us to scale safely by powering our transaction fraud model and credit underwriting process.

Deploy to your own infrastructure.
Use your existing database as your online + offline store. No bespoke storage. Everything in your cloud.
High-volume workloads at ultra-low latency.
Chalk’s Compute engine scales horizontally out-of-the-box and executes most complex queries on a Rust-based runtime for maximum performance. 100,000 QPS in < 5ms? We have you covered.
Power real-time decisions with real-time data.
Make better predictions with fresher data. Don’t pay vendors to pre-fetch data you don’t use. Query data just-in-time for online predictions.
Perfect auditability
Know everything you computed and data replay anything.
