LangChain Reportedly Nears Unicorn Status as New Round Takes Shape

LangChain, one of the early movers in AI infrastructure, is said to be raising a fresh round of funding—this time at a $1 billion valuation. That would make it one of the latest AI startups to join the unicorn club, according to people close to the deal.

The new round is reportedly being led by IVP, though the firm has declined to comment.

From Side Project to Star Player

LangChain started out in late 2022 as an open-source side project created by Harrison Chase, who was an engineer at Robust Intelligence at the time. It caught on quickly with developers who needed tools to make large language models (LLMs) more useful in real-world apps.

Back then, LLMs couldn’t do much outside of generating text. LangChain helped fix that by offering tools to:

• Connect LLMs with live data

• Run API calls

• Interact with databases and more

The developer response was massive. LangChain became a top project on GitHub, pulling in over 111,000 stars and 18,000 forks.

The buzz helped it raise two quick rounds of funding:

• A $10 million seed round from Benchmark in April 2023

• Followed by a $25 million Series A led by Sequoia, reportedly valuing the company at $200 million

The AI Landscape Shifted—LangChain Adapted

Since those early days, the LLM space has grown up fast. Big players like OpenAI and Google now offer APIs with built-in tools. Other startups—like LlamaIndex, Haystack, and AutoGPT—have launched their own frameworks, too.

That meant LangChain had to evolve. And it did.

In response, the company built LangSmith—a closed-source product that helps developers monitor, debug, and improve LLM applications.

And it’s working.

LangSmith Becomes the Star of the Show

Several sources say that LangSmith has become LangChain’s main revenue driver. The company is now earning between $12 million and $16 million in annual recurring revenue (ARR).

The product is free to start, but teams can pay $39/month for collaboration tools. Larger companies can sign up for custom enterprise plans.

LangSmith has picked up traction among developers who are building serious LLM-based apps and need ways to monitor, test, and manage them in production.

There’s growing competition in this space from smaller tools like Langfuse and Helicone, but LangChain is still seen as the leader by many.

So, What’s Next?

While LangChain didn’t comment on the funding reports, the company’s rapid growth, strong developer community, and expanding product line suggest it’s in a good position to keep growing.

This next round—if it closes at the reported $1 billion valuation—would be a major milestone. It shows that even in a crowded field, LangChain is carving out a lasting spot in the AI stack.

In Short

• LangChain is reportedly raising new funding at a $1B valuation

• It started in 2022 as a small open-source project for LLMs

• Early investors include Benchmark and Sequoia

• The new product, LangSmith, is driving $12M–$16M in yearly revenue

• Pricing starts free, with premium and enterprise options available

• Competition is rising, but LangChain remains a favorite among devs
