Mercor is an AI talent marketplace that screens credentialed professionals like physicians, lawyers, and engineers through a 20-minute AI-conducted video interview, then matches them to frontier AI labs that need RLHF training, red-teaming, or agent-evaluation work. It is built for specialized, high-stakes AI training tasks general crowdwork platforms cannot staff.
About Mercor
Mercor is an AI-powered talent marketplace founded in January 2023 in San Francisco by college dropouts Brendan Foody (CEO), Adarsh Hiremath (CTO), and Surya Midha (COO). The platform connects credentialed domain experts in medicine, law, investment banking, and software engineering with AI labs that need high-quality human feedback and training data for RLHF, alignment research, and AI agent evaluation. As of October 2025, Mercor raised a $350 million Series C at a $10 billion valuation, growing annual run-rate revenue from low double-digit millions to over $850 million in under two years.
The platform's screening mechanism is an AI-conducted video interview that generates real-time questions based on each candidate's resume and work history, then routes candidates who pass directly to matching projects without a human recruiter reviewing every application.
The expert network's specialization enables tasks involving clinical reasoning, legal document review, financial modeling, and advanced coding that platforms relying on general crowdwork cannot match. Its network of 100,000+ credentialed professionals spans 190+ countries, and weekly direct payouts make it one of the highest-paying AI training platforms available to contractors.
In March 2026, Mercor launched Mercor Enterprise AI, expanding the platform to help enterprises build an organizational context graph from data source integrations including CRMs, ticketing systems, codebases, and communications tools. The same month, a data breach exposed contractor data, including video interview recordings and biometric information, leading to multiple class-action lawsuits and material reputational risk for prospective enterprise clients.
Pricing
Custom enterprise pricing only; no public rate card. Candidates apply and interview free. Contractors earn $60-$200/hour; Mercor takes an undisclosed commission.
Enterprise clients billed hourly per expert via an Experts-as-a-Service model. Demo required for employer pricing.
Key Features
- AI Video Interview: A 20-minute AI-conducted video interview dynamically generates questions from each candidate's resume and work history, delivering a scored transcript to employers and cutting time-to-hire by up to 80% versus traditional ATS screening.
- Natural Language Talent Search: Employers at team.mercor.com search across resumes, GitHub profiles, portfolios, Twitter, and AI-generated interview transcripts in plain English, surfacing expert matches without manual Boolean queries.
- Global Expert Network: Mercor's vetted pool covers physicians, lawyers, PhDs, investment bankers, and engineers across 190+ countries, providing the specialized domain knowledge frontier labs need for RLHF, red-teaming, and long-horizon agent evaluation.
- Multimodal Data Collection: The platform handles text, image, audio, video, and code tasks in a single workflow, matching each modality to the right domain expert and delivering quality-controlled training data across all five input types frontier labs use.
- Integrated Payroll and Compliance: One-click hiring includes built-in cross-border payroll, weekly direct payments to contractors, and compliance management in 190+ countries, removing the need for separate contractor management software.
- Mercor Enterprise AI Context Graph: Launched March 2026, this feature ingests data from 34+ integrations (CRMs, ticketing, codebases, communications) to build an organizational map that helps enterprises identify where AI agents can be deployed or improved.
Pros
- Contractor pay is reported to significantly outpace general crowdwork rates on platforms like Scale AI's Outlier, with reliable weekly direct payouts rather than delayed lump-sum settlements.
- Its client roster includes some of the most demanding frontier AI labs and major technology companies, giving contractors exposure to alignment and agent-evaluation work rarely available on general AI task platforms.
- Screening happens without a human recruiter involved until after candidates are already ranked, letting hiring managers move from application to matched candidate in a single AI-scored review instead of a multi-week interview loop.
Cons
- Work availability is inconsistent: Mercor onboards more contractors than available projects, so many candidates pass the AI interview and then wait weeks or months for a match, with no way to apply to specific roles or see which companies have access to their profile.
- Serious data security concerns: the March 2026 breach exposed approximately 4TB of contractor data including video interviews and facial biometric data from 40,000+ people, triggering 7 class-action lawsuits and raising questions about whether proprietary AI methodologies were also exposed.
- No pricing transparency for employers: custom quotes require a sales call, and Mercor does not publicly disclose the commission percentage taken from contractor hourly rates, making budget planning and cost comparisons difficult.
Data Handling
- Training-data policy
- Mercor produces specialized training data for third-party AI labs; contractor data policies at talent.docs.mercor.com/policies/data-ai-usage. March 2026 breach exposed 4TB of contractor data; compliance certifications previously held were from Delve Technologies, later found to be fraudulent.
Frequently Asked Questions
What are Mercor's pricing plans in 2026?
Mercor charges employers custom enterprise rates negotiated through a sales call; there is no public rate card or self-serve tier. On the contractor side, applying and interviewing is free, and matched contractors are paid weekly at $60 to $200 per hour depending on domain expertise. Mercor takes an undisclosed commission from those hourly earnings.
Can you use Mercor without paying?
Contractors pay nothing: creating a profile and completing the AI video interview cost nothing, and there is no fee to be considered for a match. Employers face the opposite; nothing is offered at no cost, and every engagement runs through a custom enterprise sales process instead.
What are Mercor's closest competitors?
Scale AI's Outlier offers more consistent task volume for a broader contractor pool, though typical pay runs lower than Mercor's rates. Toptal uses a similar expert-vetting model focused on software engineers rather than Mercor's cross-discipline network of physicians, lawyers, and PhDs. Appen and CloudFactory suit enterprises that want annotation pipelines without a talent-marketplace layer and more pricing transparency.
What separates Mercor from Scale AI's Outlier?
Mercor vets candidates through an AI-conducted video interview and targets credentialed professionals like physicians, lawyers, and PhDs, while Outlier relies on written skill assessments and serves a broader, less specialized contractor pool. Outlier generally offers steadier task volume because Scale AI's lab relationships span more concurrent projects, whereas Mercor's per-contractor work availability is more variable. Mercor's March 2026 data breach is a security mark against it that Scale AI has not had to answer for.
How long does it take to get going with Mercor?
The contractor side moves fast: create a profile at mercor.com, upload a resume, and complete a short AI-conducted video interview that scores responses in real time, with passing candidates matched directly to open projects and no separate application step. Employers move slower by comparison, requesting a demo to start a custom hiring engagement rather than signing up directly.
