Threedays is an AI research company. We help frontier labs post-train their models on expert-verified data from manufacturing, engineering and construction, licensed from the companies that do the work.
For AI labs
We build post-training datasets, RL environments and evaluations with your research team. Every task is grounded in licensed industrial records and verified by practitioners who do the work for a living.
For data partners
Drawings, specifications, inspection reports and project files hold decades of expertise. We prepare them for AI training, remove what's sensitive, and license them to frontier labs on terms you set.
Mission
Manufacturing, engineering and construction carry the weight of everything we build. Their knowledge lives in drawings, standards and decades of practice. We exist to bring it into frontier models carefully, with the people who created it.
