Announcing HUD's $16M Series A
We raised a $16M Series A led by Standard Capital to build the software that turns data into better AI. Reinforcement learning is how frontier models improve, and HUD is the platform where anyone can build and sell the RL environments that make that happen.
Our round included participation from Y Combinator, Exceptional Capital, Liquid 2 Ventures, and Twenty Two Ventures, with angel investments from Dylan Patel from SemiAnalysis, Roon from OpenAI, Ivan Burazin from Daytona, and Theo Browne.
- 1.3M+ — Task runs
- 2,500+ — Environments created
- 15M+ — Inference calls
How We Got Here
We started HUD after building computer use agents at Hume, where we kept hitting the same wall. The agents were improving fast, but the infrastructure to train and evaluate them barely existed, so we decided to build it.
We built our own benchmarks and they got used right away. Autonomy-10 evaluated OpenAI's Operator at launch. SheetBench-50 was validated by PwC, Cisco, Charles Schwab, and Fannie Mae. OSWorld-Verified fixed more than 300 issues from the original benchmark.
