LangChain says it finished the quarter strong, with sales teams hitting 200%+ of regional targets, one rep reaching 12x quota, and more ARR booked in the last 3 months than in the previous 22 months combined.

The company also says LangSmith is now used by 30% of the US Fortune 100, and that nearly 90% of those customers use its open-source harness. The post frames enterprise demand around owning intelligence via model-agnostic tooling, control over harnesses, and memory infrastructure.
