Company Description
LangChain provides a framework for developers to build applications powered by large language models (LLMs). The company's offerings include an open-source toolkit for integrating datasets and enabling intelligent agents, a paid product called LangSmith for debugging and monitoring LLM applications, and LangGraph, a framework for building controllable agents. Its products are used by startups such as Clay and Mercor, as well as larger companies including AT&T, Home Depot, and Klarna. Founded around mid-2021 by Harrison Chase and Ankush Gola, the company has seen significant adoption, with over 50,000 applications built on its platform. LangChain secured a $25 million Series A funding round in March 2024, led by Sequoia Capital.
The company continues to expand its platform with a focus on enterprise-grade features and developer control. Recent developments include the introduction of LangSmith's Studio, an IDE for building agents, and new guardrails for PII redaction and human-in-the-loop approvals. LangChain has also introduced agent middleware for deeper customization and features for agent authentication and authorization. In June 2024, the company hosted a "Launch Week" to celebrate its third anniversary and announce upcoming product releases, signaling a continued focus on expanding its toolset for building, deploying, and managing AI agents.

Frequently Asked Questions
Joining Anduril as an employee is another way to acquire equity, typically through stock options included in compensation packages.
Is LangChain worth joining?
As an early-stage startup, LangChain has strong backing from top VCs like Sequoia and Benchmark but also faces risks common to new ventures. To make an informed decision, you can use a platform like Prospect to independently evaluate the potential value of an equity offer using data-driven models.
What should I do with my LangChain stock?
Since LangChain is a private company, your options are limited until a liquidity event, but it's wise to have a plan for your equity. Platforms like Prospect offer tools to help you manage your holdings by forecasting future value, modeling tax implications, and preparing for selling opportunities.
Can you sell LangChain stock?
As a private company, LangChain stock is not publicly traded, but employees may be able to sell shares through secondary markets or company-approved tender offers. Tools from Prospect can help you navigate these events by providing access to secondary market data and tax-optimized selling strategies.
How can I find the value of my LangChain stock?
The value of private stock is often based on a 409A valuation or the price from a recent funding round, which isn't always transparent. You can use platforms like Prospect, which leverage VC-grade data and predictive models to help project the potential future value of your equity.
What is LangChain's equity worth?
LangChain's most recent company valuation was reported to be over $200 million following its Series A funding round. To estimate what your specific equity grant could be worth, you can use an equity calculator or a platform that models future value based on company performance and market data.
What is LangChain's stock ticker symbol?
LangChain is a private company and does not have a stock ticker symbol because its shares are not traded on a public stock exchange. Therefore, you cannot find it on platforms like the NYSE or NASDAQ.
Can I buy or sell LangChain stock?
Because LangChain is a private company, its stock is not available for purchase by the general public on stock markets. Selling is typically restricted to specific events like secondary market transactions or tender offers, which platforms like Prospect can help you prepare for.
What is the criteria to buy or invest in LangChain stock?
Investment in a private, venture-backed company like LangChain is typically limited to accredited investors and venture capital firms participating in organized funding rounds. The general public cannot invest, and there are no publicly stated criteria for participation in these private placements.
