San Francisco Bay Area — AI × Robotics
GANDHARV MAHAJAN

Building frontier AI evaluations, agentic benchmarks, and embodied robotics systems. I sit at the intersection of rigorous ML research and real-world deployment.

I build the systems that make frontier AI models better — from crafting evaluation datasets that probe real reasoning failures, to designing agentic benchmarks that stress-test long-horizon planning. Currently at Labelbox, I've helped grow one account from $0 to $25M ARR while pushing the state of RLHF and RLVR for the world's top AI labs.

On the robotics side, I spent years at Duality building closed-loop simulations, synthetic data pipelines, and digital twins using NeRFs and Cycle-GANs. I believe the best AI is shaped by people who understand both the math and the metal — the loss curves and the actuators.
