Benchspan

Benchspan is a Y Combinator-backed company that run agent benchmarks in minutes, not hours. Based in San Francisco, USA, the company participated in the Spring 2026 batch of Y Combinator.

Benchspan is a benchmarking platform for AI agents. If you're building an agent, you need to know if it's getting better. But running benchmarks is slow, expensive, and fragile. You spend days writing glue code every time you want to run a new benchmark, runs take forever on your laptop, and when they fail halfway through you burn hundreds of dollars in tokens with nothing to show for it.

Benchspan fixes all of it. Onboard your agent once, and it works with every benchmark on the platform.

Benchspan was part of Y Combinator's Spring 2026 cohort, has a team of approximately 2 employees, and is actively operating.
