Multi-Domain

Platforms that build environments, evals, and benchmarks across many domains at once: generalist environment foundries serving frontier labs with everything from coding to customer support. Scale is their moat: thousands of environments, expert networks in every field, and pipelines that turn any workflow into a training ground.
