Mercor
Contractor pay plus a platform fee of about 30%
What is Mercor?
Mercor was founded in San Francisco in 2023, employs roughly 300 to 400 people and screens applicants with AI interviews. It raised money at a $10 billion valuation in October 2025, mainly on the strength of supplying experts to AI labs. Its fee is the clearest thing to understand about buying from it: Sacra estimates it at about 30% on top of contractor pay. That model suits large, short-term expert work. For a year-long engineering seat, the fee adds up.
Mercor works primarily with clients in AI labs, Technology, Finance, Legal, Healthcare sectors. Its primary differentiator is: Volume contractor hiring with a percentage platform fee.
