Open source agentic startup LangChain hits $1.25B valuation
LangChain raised $125 million at a valuation of $1.25 billion, the company said announced on Monday. TechCrunch reported in July that the provider of a popular open source framework for building AI agents was raising new funds at a valuation of at least $1 billion. The deal was led by IVP, as we previously reported. New investors CapitalG and Sapphire Ventures joined, as did existing investors Sequoia, Benchmark and Amplify.
LangChain started in 2022 as an open source project founded by machine learning engineer Harrison Chase. The startup was an early darling of the AI era, solving problems that made building apps with early-stage LLMs difficult, such as searching the web, calling APIs, and interacting with databases. It became a huge success and Chase launched a startup with one $10 million seed round from Benchmark in April 2023. A week later, Chase raised a $25 million Series A led by Sequoia, reportedly valuing LangChain at $200 million.
As state-of-the-art modelers have added more infrastructure, LangChain has evolved into a platform for construction agents. In addition to announcing its unicorn status, the company launched updates to all its major products, including its agent builder LangChain, its orchestration and context/memory tool LangGraph, and its testing/observation tool LangSmith. LangChain remains extremely popular among open source developers, with 118,000 stars and 19.4 forks on GitHub.
