Today, HUD is excited to share our Series A funding!

We are the platform for building high quality post training datasets. Over 50 businesses use HUD to build RL environments, sell them to AI labs, or train their own models from them.

Our mission is to enable a generation of data entrepreneurs. The previous generation built apps to impact the world. We believe people will build infrastructure around data, both digital and physical, that align AIs to their specific goals.

We’ve raised $16M in total funding from @Standard_Cap, @ycombinator, @ExceptionalCap, @Liquid2V, @twentytwovc , amazing angels such as @dylan522p from @SemiAnalysis_, @tszzl, @ivanburazin, @theo, and more!

HUD is a very interesting company, the big idea here is to provide entrepreneurs anywhere in the world the tools and infrastructure they need to get into the data business.

Since leading @hud_evals Series A, I recorded an interview with the founders to discuss what HUD is, who it's for, and why creating a toolset + marketplace for RL environments is such an interesting problem to work on.
