Halluminate is building AI training environments, starting with finance

Y Combinator says Halluminate is building reinforcement learning environments and benchmarks to help AI models practice knowledge work beyond coding, starting with finance. In a fireside conversation, the company’s co-founders describe how testing browser agents led them to build environments for tasks such as financial modeling. They argue that better verification, not just more training tasks, is critical, and discuss the possibility of simulated companies where AI agents learn to work together.
