LangChain, an AI software company offering tools that help developers build applications using models like GPT-4, raised $100 million in funding at a $1.1 billion valuation, according to information Sources familiar with the deal confirmed. The company, whoseoti 2025 Forbes AI 50 list and 2024 Forbes Next Billion Dollar Startups List feature them, was valued at around $16 million annually. Without previous reports, the funding was not previously published. This round was led by IVP Capital, a venture capital firm, according to sources.
LangChain’s mission is to accelerate the creation of AI-powered applications for developers by enabling the development of open-source software with minimal code. Founded in 2023, the company initially developed a tool, LangSmith, designed to help developers evaluate, monitor, and debug code with ease. As of now, the team has introduced a new product, LangGraph, aimed at assisting businesses in developing AI agents that can execute specific tasks autonomously.
LangChain has already established partnerships with various AI start-ups, including some big names like Uber, LinkedIn, andbesic Mercor and Lovable. For instance, the company’s product LangSmith has been used by over 40,000 teams across tech giants, as well as startups like Three-Love.com and Rough Protocol. In its early part of the year, LangChain introduced LangGraph, which has garnered over 20 million monthly downloads. The company’s team serves as a bridge between mainstream developers and tech startups, helping them reach high volumes of downloads as part of a broader growth trend in AI.
The round that brought the funding came shortly after a previous Series A round led by Sequoia VCs in 2024, which raised $20 million and valuing LangChain at $200 million. LangChain’s current valuation reflects its growth and potential to expand its reach, having already positioned itself for scalability. The team and investors are targeting industries such as healthcare, engineering, and finance, where AI is already playing a significant role.
Despite its established position in the AI ecosystem, LangChain is well-positioned to compete with other AI tools focused on tasks like autocomplete or formulating legal documents, such as Cursor. Additionally, Lovable serves as a tool that automates integration by bypassing the need for developers to learn complex workflows. This makes LangChain the only AI software developer in the US before explicit mention of Cursor and Lovable. The potential for expansion into other areas, such as real estate or finance, remains, with interest from companies into the mid-sized range.
In conclusion, LangChain is uniquely positioned to deliver value to developers and businesses that rely on automating the AI development process. By leveraging its existing codebase and the valuations of well-funded startups like Lovable and Cursor, the company is well on its way to building a scalable ecosystem that positions itself to compete with others in the space. With a focus on the opportunities in healthcare, engineering, and finance, LangChain is expected to continue its momentum as a leader in the AI developer space.
