Every AI agent developer has lived this nightmare: the agent works perfectly in testing, then falls apart on real users. Hue, part of Y Combinator's Fall 2026 batch, attacks the problem with fake but realistic worlds — you describe a world like "a 15-person startup that uses Gmail, Notion and Slack," and Hue builds a simulated copy filled with months of believable data for your agent to run against.
The cleverest part is the feedback loop: Hue can rebuild a world from your agent's real traces, so every strange thing users do after launch becomes a new test scenario. It's part of a maturing agent-testing category alongside swarm-testing tools like Composal — the gold rush is over, and the infrastructure era has begun.
