Polymath

Simulation environments to train & evaluate long-horizon AI agents

Y CombinatorWinter 2026ActiveB2B

What they do

Problem

Long-horizon AI agents are unreliable to train and evaluate safely because real-world testing is costly, risky, and lacks realistic environments.

Solution

Polymath builds realistic simulation environments where autonomous agents can be trained, practiced, and evaluated over long horizons.

Who it's for

AI researchers and companies building autonomous agents who need simulation-based training and evaluation.
