Hear from our happy customers
LangChain, LangGraph, and LangSmith help teams of all sizes, across all industries - from ambitious startups to established enterprises.
“LangSmith helped us improve the accuracy and performance of Retool’s fine-tuned models. Not only did we deliver a better product by iterating with LangSmith, but we’re shipping new AI features to our users in a fraction of the time it would have taken without it.”
“By combining the benefits of LangSmith and standing on the shoulders of a gigantic open-source community, we’re able to identify the right approaches of using LLMs in an enterprise-setting faster.”
“Working with LangChain and LangSmith on the Elastic AI Assistant had a significant positive impact on the overall pace and quality of the development and shipping experience. We couldn’t have achieved the product experience delivered to our customers without LangChain, and we couldn’t have done it at the same pace without LangSmith.”
“As soon as we heard about LangSmith, we moved our entire development stack onto it. We could have built evaluation, testing and monitoring tools in house, but with LangSmith it took us 10x less time to get a 1000x better tool.”
