## Resource

AI agents are evolving from Q&A bots to full-fledged task-doers—booking trips, managing finances—but trust is the big hurdle. Enter Patronus AI, a startup backed by former Meta researchers, building simulated digital worlds to rigorously test these agents using reinforcement learning. Think of it as virtual crash-testing for AI, catching dangerous shortcuts before they hit real users. Already backed by $50M in Series B funding (totaling $70M), Patronus is attracting major AI labs and startups. Their approach mirrors self-driving car training: stress-test in controlled environments first. Focused on software and finance now, they’re aiming for fully automated, long-term agent testing—no humans needed—and could soon rival internal AI labs.
