## About

Based in California, US, Chalk AI, Inc. operates as a data infrastructure for machine learning and generative Artificial Intelligence. In May 2025, Chalk AI, Inc raised USD 50 million in series A funding led by new investor Felicis Ventures, with participation from returning investors General Catalyst Partners, Unusual Ventures, and Xfund. The company's flagship product is a data platform designed explicitly for machine learning tasks. Leveraging the power of Rust compute and just-in-time data capabilities, it offers feature pipelines in idiomatic Python, empowering users with robust data engineering workflows minus the infrastructure complexities. Its toolchain for LLMs (presumably machine learning models) facilitates real-time decision-making by harnessing real-time data. The company will use the May 2025 funding for growth and development.
