Patronus AI
LLM evaluation platform — $50M Series B, pivoting to agent simulation.
About
Patronus AI (patronus.ai) is an enterprise LLM evaluation platform: automated evals, safety/security testing, and hallucination detection for production LLM systems.
$50M Series B in June 2026 (TechCrunch). Caveat: the company is pivoting toward 'Digital World Models' — agent simulation environments — so the future of the standalone eval platform is unclear. Evaluate the current product on its merits, but watch the roadmap before committing long-term.
