Overview
- IVP led the round, joined by existing backers Sequoia and Benchmark and new strategic investors including CapitalG, Sapphire Ventures, ServiceNow Ventures, Workday Ventures, Cisco Ventures, Datadog, Databricks, and Frontline.
- LangChain originated as an open‑source framework that links large language models to external data and tools and now monetizes with LangSmith for testing, deployment, and observability.
- The company’s agent stack includes LangGraph for long‑running workflows and Deep Agents for multi‑step reasoning, complementing its core chains library.
- LangChain reports usage by enterprise teams at Cisco, Workday, Cloudflare, ServiceNow, Replit, and Clay.
- TechCrunch reported June ARR of $12–16 million, which the company says has since grown, and LangChain remains unprofitable but describes its spending as efficient in a crowded agent‑tooling market.
