CueBench
CueBench builds reinforcement-learning environments for frontier AI labs, focused on scientific reasoning and performance engineering - the kinds of hard, specialized tasks where the best models still fail more than 80% of the time. The company's bet is that the next gains in model capability will come less from raw pre-training and more from training agents inside carefully constructed environments that force them to learn the things they are currently bad at. Founded in 2026 by Dillon Mehta, Rishan Hemrajani, and Neel Gadde, CueBench is part of Y Combinator's Summer 2026 batch and is backed by NVIDIA Inception.
