What We Do
Atla is the eval and improvement platform for AI agents. We help teams find and fix agent failures—fast. As agents grow more complex, debugging and improving them has become a significant challenge. Atla brings clarity by tracing every step, surfacing error patterns across runs, and delivering specific suggestions to improve agent performance. With real-time monitoring, automated error detection, and tools for prompt experimentation, Atla gives teams the visibility and control needed to confidently ship agentic systems that work. We’re a team of researchers, engineers, entrepreneurs and operational leaders. Our expertise in evals was honed through training our own purpose-built LLM Judges, Selene and Selene Mini, which are available open-source and have been downloaded 40,000+ times. Atla is backed by Y Combinator, Creandum, and the founders of Reddit, Cruise, Rappi, Instacart and more. Blog: https://atlaai.substack.com/
