| 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.AI Model Training Data: Source high-quality, nuanced data for RLHF, fine-tuning, and rubric development across any domain.Managed Data Services: Offload the entire process of sourcing, vetting, and managing expert teams for complex AI training projects.APEX Benchmarking: Use Mercor’s platform to evaluate and benchmark your model’s performance on real-world, economically valuable tasks.AI-Powered Vetting: (For hiring) Automate the screening of technical talent with in-depth, AI-led video interviews that test real skills. For Experts & Candidates: 
High-Value Opportunities: Get matched with high-paying, remote, and flexible hourly roles (often $40 – $130+/hr) at leading AI companies.Shape the Future of AI: Apply your deep domain knowledge (in law, medicine, finance, etc.) to directly train and improve frontier AI models.Meritocratic Vetting: Your skills are assessed through an objective, AI-led interview process, focusing on capability over resume keywords.Streamlined Payments: The platform handles all contracting and ensures prompt, reliable payments for work completed. | 
| Use cases and applications | 
Reinforcement Learning from Human Feedback (RLHF): AI labs hire experts to review, rank, and improve AI-generated responses.Expert Data Generation: Creating high-quality, specialized datasets (e.g., legal briefs, medical diagnoses, financial models) for model training.AI Model Evaluation: Using domain professionals to create rubrics and score AI model outputs for accuracy, safety, and nuance.AI Benchmarking: Powering benchmarks like APEX to measure AI’s real-world capabilities in complex professions.Technical Recruiting: (Original use case) Companies use the platform to source, vet, and hire top software engineers and other knowledge workers. | 
| Who uses? | 
Top AI Research Labs: Companies building and training frontier large language models (Mercor states it’s used by “all of the top 5 AI labs”).Elite Domain Experts: Professionals with deep expertise, such as lawyers (JDs), doctors (MDs), scientists (PhDs), financial analysts, and consultants.Software Engineers & Technical Talent: Developers and other knowledge workers seeking high-quality, remote contract roles.Enterprise Companies: Businesses using the platform to hire vetted talent or source expert data for internal AI projects. | 
| Pricing | 
For Experts (Candidates): Free to join. Experts are paid a high hourly rate for their work, which is set by the company hiring them (e.g., $35/hr to $130+/hr).For Companies (Clients): Mercor uses a commission-based model. It charges the company an “hourly finder’s fee and a matching rate” on top of the expert’s hourly pay. |
