About

Harrison Chase open-sourced LangChain in October 2022 — an 800-line Python package that caught the ChatGPT wave to become the default way developers wire language models into applications — and built the company behind it to a $1.25 billion valuation in its October 2025 Series B led by IVP. A Harvard statistics-and-CS graduate who wrote quantitative sports analysis as a student, he led entity-linking at Kensho and the ML team at Robust Intelligence, where he met co-founder Ankush Gola. LangSmith and LangGraph turned the library into the orchestration stack for production agents, and Chase's 'context engineering' framing has become industry vocabulary.

Beyond investing

Founded: Released LangChain as an ~800-line open-source package on October 24, 2022, and incorporated the company in January 2023 with Ankush Gola.
Communities: Wrote quantitative sports pieces — NBA player progression, NFL coaching analysis — for the Harvard Sports Analysis Collective as a student.
Awards: Forbes 30 Under 30, Enterprise Technology (2024).
More: Met co-founder Ankush Gola when both worked at Robust Intelligence. LangChain's GitHub stars ran from 5k to 96k+ in under two years, with 28M monthly downloads by the end of 2024. Popularized 'context engineering' — the framing that when agents fail, it's usually the context, not the model.
