About
Baserun is a San Francisco-based LLM observability and evaluation platform — backed by Y Combinator (S23) with $500,000 in seed funding — providing AI application developers and engineering teams with testing, monitoring, and evaluation infrastructure for large language model features and agents: an SDK-based logging system that captures prompt templates, input variables, outputs, cost, latency, and token usage per LLM request, combined with a visual evaluation interface for systematically testing LLM application behavior against defined quality criteria. Founded in 2023 by Effy Zhang and Adam Ginzberg to address the visibility gap that makes production LLM applications difficult to debug, evaluate, and improve.
