Founder & CEO of LangChain
"Harrison Chase created LangChain and LangGraph, orchestrating how developers connect LLMs to databases, APIs, and autonomous agents."
Harrison Chase
Founder & CEO • LangChain
In late 2022, Harrison Chase released LangChain as an open-source Python library to connect large language models with external data sources. Within months, it became the fastest-growing AI repository on GitHub.
As enterprises moved from simple prompts to complex multi-agent systems, Chase introduced LangGraph and LangSmith—enabling companies to debug, monitor, and deploy reliable stateful AI workflows.
By 2026, LangChain is an indispensable part of the enterprise AI developer stack, backed by Benchmark and Sequoia Capital.
"LLMs alone are impressive, but context and memory are what make them truly useful inside real software systems."
— Harrison Chase, LangChain
