LangSmith for Startups

LangChain, Inc.'s LangSmith for Startups is an in-kind support program for early-stage AI startups building with LangChain's platform. It sits under LangChain's product umbrella and is aimed at founders who need observability, evaluation, and deployment support more than capital. The Build tier offers discounted seat pricing for first-time customers with less than $10 million raised and at least $25,000 in seed funding. The Scale tier adds $10,000 in LangSmith credits, valid for one year or two years for Y Combinator participants, plus office hours, Slack access, event invitations, and startup spotlights. Scale applicants also need backing from a LangChain premier VC partner. Applications are reviewed on a rolling basis, and the program is not a cash grant or research award. The clearest fit is a startup with an active LangSmith use case, a real funding history, and a reason to trade equity-free support for product credits and discounted access. Founders using agents in production can use the program to lower early operating costs while they validate performance.
