LangChain Raises $125 Million at a $1.25 Billion Valuation

LangChain is a leading startup at the forefront of providing tools for developers to build artificial intelligence agents. The company focuses on developing a software framework that streamlines and accelerates the creation of sophisticated, data-aware applications powered by language models.

LangChain has raised a $125 million Series B funding round, bringing the company's valuation to $1.25 billion. The round was led by IVP alongside Alphabet Inc.’s CapitalG fund, ServiceNow Ventures, Workday Ventures, Cisco Investments, Datadog, and Databricks.

LangChain, headquartered in San Francisco, California, United States, was founded in 2022 by Harrison Chase and Ankush Gola. In July 2025, the company joined the unicorn club. “Our goal is to figure out what the agents of the future look like and build tools to facilitate that. We know what some of those pieces are (an agent runtime like LangGraph, observability, evals),” wrote LangChain co-founder and CEO Harrison Chase in the company’s blog post. “We have some hunches about what the other pieces are that we are actively exploring. We also fully expect that there will be other components that, at this moment in time, we can't imagine what they'll look like – which makes this journey incredibly fun and rewarding for what we expect to be a long time.”
