# Harrison Chase

## Profile

**Harrison Chase** is the founder of [[entity-langchain]], one of the dominant frameworks for building LLM applications and RAG pipelines.

## Role in This Source

Quoted (see [[quote-harrison-chase-context]]) from a Sequoia Capital interview, capturing the industry's shift in framing:

> *"Everything's context engineering. Context engineering is such a good term, I wish I came up with that term because it describes everything we've done at LangChain without knowing the term existed."*

This quote functions as the speaker's **external validation** that prompt engineering is over and [[concept-context-engineering]] has taken its place.

## Enrichment Caveat

The enrichment overlay was **unable to verify** this exact quote attribution to a Sequoia interview. The directional sentiment is consistent with Chase's public commentary, but the specific wording and venue should be cross-checked.
