About AgentHub

At AgentHub, we’re building the simulation and evaluation engine for AI agents. As agents become more powerful, complex, and widely deployed, the need to efficiently and thoroughly evaluate them grows significantly. Our platform enables teams to measure safety, reliability, and quality by testing agents in realistic environments, surfacing insights, and driving improvements.

We’re an early seed-stage startup, built by the former tech lead of Apple’s Foundation Model Evaluation team and CMU and MIT grads and backed by Y-Combinator, leading VC’s, and angels.

Joining AgentHub means working directly with the founders on high-impact problems, shaping the culture, and building the critical infrastructure layer that will make complex, agent-driven products possible. If you want to work at the frontier of AI, where research meets real-world systems, we'd love to hear from you.
