Harrison Chase — CEO, LangChain

**Harrison Chase** is the founder and CEO of **LangChain**, the most widely-used framework for building applications with large language models. A former ML engineer at Robust Intelligence, he created LangChain as an open-source project in late 2022 and rapidly grew it into a company with massive developer adoption — the LangChain Python package was one of the fastest-growing open-source projects in history, reaching 50,000+ GitHub stars within months.\n\nHarrison's perspective is from the 'picks and shovels' layer of the AI gold rush — he builds the infrastructure that AI application developers use. His evaluation lens is developer adoption, composability, and whether the AI application architecture is sound.
