Mendable.ai is a platform that uses AI to help enterprise teams answer technical questions with the help of LangChain Agents and LangSmith. The company has seen significant efficiency improvements, including $1.3 million in savings, by equipping customer success and sales teams with GTM assistants. These assistants can now take action, enabling even more efficiency improvements. Mendable is expanding its capabilities to enable chatbots to access and utilize a wider range of data sources and perform various automated tasks. The introduction of Tools & Actions in Mendable expands its capabilities, giving users the ability to create their own tools via an API call. LangSmith, a debugging tool from LangChain, has been instrumental in helping Mendable optimize its tools and action module, providing visibility into agent behavior and improving debugging processes. With LangSmith's help, Mendable was able to identify issues such as slow response times and optimize its prompt generation process, resulting in reduced latency overall. The company is now using LangSmith to build a dataset of optimized tool inputs and outputs, making it easier to evaluate and improve the performance of its tools.
