Harrison Chase is the co-founder and CEO of LangChain, the open-source framework that became the default scaffolding for developers building LLM-powered applications. Starting as an 800-line Python package he wrote as a side project in October 2022, LangChain has grown to serve 1 million+ developers, 80 million monthly downloads, and blue-chip enterprise customers from Uber to JPMorgan - reaching a $1.25 billion valuation after a $125 million Series B in October 2025. A Harvard-trained statistician who got into machine learning through sports analytics, Chase built LangChain to solve the problem he kept running into at work: there was no good way to chain LLM calls together into reliable, production-ready applications.
