Halluminate is an applied AI and data company working with frontier Labs (ex. OpenAI, Anthropic, etc) to train Financial Services Super Intelligence. We do this by building high quality computer and tool-use RL (Reinforcement Learning) gyms to train AI agents that do work across financial services verticals. (ex. excel modeling, powerpoint creation and more in Investment Banking, Private Equity, Hedge Funds, etc.)
The company recently graduated from YCombinator (S25) and raised a seed round to scale their team and support growth.
