Mercor is an American company founded in 2023 by three Thiel Fellows that recruits and pays domain experts to produce the training and evaluation data frontier artificial intelligence labs need. Its business shifted quickly from general talent matching to expert data work: as models became competent at ordinary tasks, the scarce input became judgement from practising doctors, lawyers, bankers and engineers, and Mercor sources, vets and pays those people at very large scale. Headquartered in San Francisco and valued in the billions within two years of founding, it pays out enormous sums annually to a contributor network rather than employing them.

Lila Sciences is an American company launched publicly in 2025 out of Flagship Pioneering with the aim of building what it calls scientific superintelligence: artificial intelligence systems that generate hypotheses and then test them in the company's own automated laboratories. Its distinguishing feature is the closed loop between model and experiment, since most scientific machine learning is limited by the fact that the data it needs has never been generated. Headquartered in Cambridge, Massachusetts and funded at an unusually large scale for a company at this stage, it is working across life sciences and materials chemistry rather than committing to a single field.
