Halluminate: <10 People, 4 of Top 5 US AI Labs, $30M Series A for RL Environments
ycombinator · x · 2026-10-01
In a YC fireside chat, Halluminate's co-founders explain their pivot from evals to building RL training environments. Key points:
- A team of fewer than 10 works with four of the top five closed-source US AI labs, and recently raised a $30M Series A
- Started by testing browser agents, then realized models need environments to practice tasks like financial modeling
- Core thesis: better verification, not just more training tasks, is what makes models smarter
- Long-term vision: simulated companies where teams of AI agents learn to collaborate
- Also covers AI safety and team building
