Kill Reason

Patronus AI's Generative Simulators is EXACTLY the described product. 10+ funded players with $308M+ combined capital (Braintrust $800M valuation, Galileo $68M, Arize $70M). AWS AgentCore and Azure AI Foundry shipping built-in evaluation. Massive open-source pressure (DeepEval 400K+ downloads, Arize Phoenix 2M+ downloads). The timing thesis was backwards — 57% of organizations already have agents in production NOW.
