Tribe AI vs Mercor: overview
Tribe AI
Jaclyn Rice Nelson and Noah Gale started Tribe AI in 2019 to help companies hire contract AI talent, and TechCrunch reports it ran bootstrapped for six years before raising venture money in 2024. The business has since grown into a full AI services firm, but its talent model still rests on a network: Tribe says more than 600 AI engineers and product leaders work with it as per-project consultants. Engineers now work as forward-deployed teams inside the client organization, against its real systems. Built In lists about 35 employees, which fits a firm whose bench is mostly contractors.
Mercor
Mercor was founded in 2023 and uses AI agents to interview and match contractors, and in October 2025 it closed a Series C at a $10 billion valuation. It began by hiring software engineers, and a spokesperson said in 2025 that engineers were still its most requested talent. More than 90% of its revenue, though, now comes from AI model companies buying expert work for training data. It still places people in full-time, part-time and contract roles with other clients, and an analysis by Sacra puts its recruiting fee at 30%.
