Mercor

Originally founded as a recruiting marketplace, Mercor executed a strategic pivot that transformed it into the expert service layer for frontier model development. Mercor's AI-powered vetting system conducts structured 20-minute video interviews to source, screen, and deploy hundreds of domain experts. As of February 2025, the platform had evaluated 468K applicants and built a proprietary dataset on talent quality, creating compounding advantages. Better vetting leads to higher-quality placements, further improving matching algorithms by generating performance data. As post-training becomes a primary driver of model differentiation and AI labs race to secure access to specialized human intelligence, Mercor looks to own the talent layer that makes frontier AI development possible while building network effects that become harder to replicate with each successive placement.
