Harrison Chase (Co-founder & CEO of LangChain) joins Jay to discuss the evolution from LangChain's Twitter origins to becoming the infrastructure backbone for thousands of production agents.
Harrison talks about how LangChain started on Twitter and quickly grew into a multi-product ecosystem including; LangChainLangSmithLangGraph, and LangGraph Platform.
The conversation revolves around deep agents, permission models, the issue with memory, and what the future holds for the coding space.
Harrison explains why competing directly with model providers on their specialized domains (like Anthropic's Claude Code) is nearly impossible, but argues the real opportunity lies in UX innovation and bringing these capabilities into existing workflows.
Tune into the full episode to learn why memory isn't the bottleneck yet and how the bitter lesson applies to agent architecture!
