Atla is a London, United Kingdom-based AI agent evaluation and improvement platform — backed by Y Combinator (S23) with $5 million raised in a seed round in December 2023 led by Creandum with YC and angels including founders of Reddit, Cruise, Rappi, and Instacart — providing AI agent development teams with an LLM judge-based evaluation engine that automatically analyzes agent traces to identify error patterns, root causes of failures, and fix suggestions, reducing the time to discover and debug recurring agent failures from days to hours for teams building agentic AI applications. Founded in 2023 by Maurice Burger and Roman Engeler with a 10-person team, Atla serves the growing ecosystem of AI agent developers who face the challenge of systematically improving agent reliability without manually reviewing thousands of execution traces.
