Company Description
Chalk is a software development company that provides a data platform for machine learning and artificial intelligence applications. The platform allows data teams to define features and their data dependencies in Python, which Chalk then compiles into data pipelines using a Rust-based engine. This system is designed to serve consistent data for both model training and live inference, with capabilities for real-time querying, caching, and debugging. The platform can connect directly to data sources such as production databases, external APIs, and S3 files, aiming to reduce the need for separate ETL jobs. Founded in 2022, the San Francisco-based company has since expanded with an office in New York. It has raised a total of $60 million through several funding rounds, including a $50 million Series A round in May 2025, and has grown to 68 employees.
The company is currently expanding its go-to-market teams and developer advocacy, indicating a focus on growth and community engagement. Recent developments include the release of 'chalk diff,' a command-line tool for comparing feature code to aid in code reviews and debugging. Chalk was also named to Fast Company's "Next Big Things in Tech 2025" list. Customer use cases highlight the platform's application in production environments. For example, the company Verisoul utilized Chalk to increase its model deployment speed by a factor of ten for its fraud detection systems. Another customer, Whatnot, used the platform to accelerate the development of new recommendation algorithms and enhance its fraud detection capabilities.
