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, led by Felicis.
We’re hiring a VP of Sales to take a strong early GTM motion and scale it into a world-class revenue engine. Chalk already has traction with leading enterprise customers and a proven motion led by the founding team. Your mandate is to build on that foundation—bringing structure, repeatability, and leadership to help us scale revenue, grow the team, and win key markets.
You'll report directly to the CEO and work closely with product, engineering, and marketing to drive strategic deals and build a sales org that thrives in complex, technical environments.

You’ll be joining a technical, fast-moving team at the inflection point: strong product-market fit, happy customers, and a clear path to scale. If you’ve done this before—and you’re excited to do it again, with even more ownership—let’s talk.
Meet Chalk Chalk is building machine learning infrastructure to answer the world’s hardest questions. Our platform is built to power credit, risk, insurance, medical, and recommendation decisions for the world’s most innovative companies. Answering these complex questions requires sourcing data from a wide range of providers and rapidly iterating on feature definitions. Chalk makes it easy for machine learning teams to build high-performance pipelines that deliver data to models at the right time. We orchestrate infrastructure and automatically track data lineage so developers can work confidently and focus on their unique products and insights. 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.
