Chalk, a San Francisco company developing AI infrastructure solutions, announced a $50 million Series A funding round led by Felicis. The company works to enable real-time inference for sectors like fintech, healthcare and e-commerce to help them meet the demand for new data and complex computations needed for decision making.

Counting organizations including Sunrun, Whatnot, Found and Iwoca among its customers, Chalk aims to provide intuitive data infrastructure that integrates with the tools developers already use. Its solution is designed to effectively handle sophisticated data interactions as apps leveraging large language models, or LLMs, grow in complexity.

The Series A funding round will allow Chalk to build a general compute framework and enhance platform integration and usability. The company’s goal is to help developers seamlessly create transformative real-time AI applications.
