Name Mercor AI
Overview Mercor is an advanced AI-powered platform that operates at the intersection of elite human expertise and artificial intelligence development. Originally an AI-driven platform for sourcing, vetting, and hiring technical talent, Mercor has evolved into a critical partner for the world’s leading AI laboratories. Its primary function is to provide a “human data layer” for the AI frontier. Mercor connects AI companies with a vast, global network of over one million vetted domain experts—including doctors, lawyers, financial analysts, PhD scientists, and senior engineers. These experts are hired for high-paying, remote, hourly contracts to perform complex tasks that train, evaluate, and refine next-generation AI models. This process, often involving Reinforcement Learning from Human Feedback (RLHF), helps AI develop the nuance, judgment, and real-world reasoning that data alone cannot provide. Mercor also created APEX (The AI Productivity Index), a major benchmark that uses these experts to measure how well AI models perform high-value, real-world economic tasks in fields like law, medicine, and finance.
Key features & benefits For AI Labs & Companies:

  • Access to Elite Experts: Instantly tap into a vetted network of top-tier professionals (JDs, MDs, PhDs, etc.) for specialized data generation.
