Meet 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.

Meet Our Founders

• Elliot started his career at Affirm where he built the early risk and credit data infrastructure system (the inspiration for Chalk). He then started Haven Money (with Andy) which Credit Karma acquired to power its banking products.
• Andy met Elliot at Stanford admit weekend – Elliot was his room host and they’ve been best friends ever since. After school, Andy worked at Palantir on large government data infrastructure projects. He then founded Haven Money (with Elliot) which now powers Credit Karma Money.
• Marc spent many years at Google where he helped to launch the first version of Google Wallet. He went on to start Index which Stripe acquired as its in-store payment solution – it’s now called Stripe Terminal.
