Is Mercor Legit? Review of Pay, Jobs and Risks
Many experts get invited to work for Mercor and wonder if it is real. The pay looks high, so does the company’s valuation, but so are the questions about privacy after a 2026 security incident.
This review covers how Mercor works, what it pays, real company numbers, and the risks, updated for September 2026.
What Is Mercor
Mercor is an AI talent marketplace founded in 2023. It connects vetted experts with AI labs and companies that need people to train and check AI models. It was started by three 23-year-old cofounders, Brendan Foody and Adarsh Hiremath as co-CEOs and Surya Midha as board chairman, who met on their Bay Area high school debate team and became the world’s youngest self-made billionaires in October 2025.

Pricing
Mercor is free for workers. One 2026 review reports pay from about $12 to $25 per hour for entry work, about $25 to $53 for mid level trainers, and about $75 to $200 or more for domain experts. It also reports weekly payments. Rates and projects change often.
How Big Mercor Has Actually Gotten
Mercor’s growth has been extraordinarily fast for a company built on hiring freelance experts rather than selling software. It reached a $10 billion valuation after a $350 million round in September 2025, and was in talks for a $500 million round at a $20 billion valuation by July 2026, doubling in roughly nine months. Annualized revenue crossed $1 billion in February 2026 and reached $2 billion by June 2026, a pace the company describes as among the fastest revenue growth of any startup in the current AI boom. Mercor now counts nearly five million registered experts on its platform, connecting them with AI labs including OpenAI that need specialized people to create and check training data.
Pros
- High hourly pay for specialists
- Flexible remote work
- Weekly payment reported
- Real projects from known AI labs
- Backed by a company with real revenue and major venture investors
Cons
- Work can be uneven
- Rejections often come with no feedback
- Support can be slow
- Time tracking software is used
- A March 2026 data breach affected a subset of experts’ sensitive information
What Actually Happened in the 2026 Data Breach
In March 2026, a supply chain attack compromised LiteLLM, an open-source tool, with a malicious actor publishing tampered versions designed to steal credentials from any system that installed them. Mercor said that out of nearly five million experts, only a limited subset had sensitive information affected, and it began notifying affected individuals starting June 25 and 26, 2026. No Mercor employees were affected, and the company said it found no evidence the exposed data had been used fraudulently. Mercor brought in third-party forensics firms including Google’s Mandiant and Latacora, coordinated with law enforcement, rotated credentials across its cloud platforms and GitHub, and offered affected workers free TransUnion identity protection. Several lawsuits were filed against the company over the breach in the months that followed.
Who Mercor Is Best For
Mercor fits credentialed experts such as doctors, lawyers, scientists, and senior engineers who want flexible side income. It is not a stable primary job, and given the 2026 breach, it is worth being selective about what personal information you share during onboarding.

How Mercor’s Pay Compares Across the Expert Data Market
Mercor operates inside a fast-growing niche sometimes called the expert data labor market, valued at roughly $2.32 billion in 2026 and projected to reach $6.53 billion by 2031 at a 22.95% compound annual growth rate. That market has stratified into clear pay tiers: frontier experts doing PhD-level work like RLHF and reasoning evaluation earn $85 to $200 or more an hour, mid-tier domain specialists in finance, medicine, or law earn $20 to $85 an hour, and bulk commodity labeling work pays $1 to $12 an hour, a wage gap of up to 150 times between the top and bottom of the market.
Within that market, one industry report put Mercor’s average hourly rate around $85, with senior experts earning $200 or more, sourced through its roughly 20-minute AI video interview process and drawing on more than 30,000 weekly active experts. That puts Mercor in a similar pay range to competitors like Surge AI, which uses trust-score credential vetting across about 50,000 experts at $50 to $200 an hour, and below newer entrant Handshake AI, which sources from a pool of 500,000 PhDs and 3 million master’s degree holders at $100 to $125 an hour. Sourcing vendors across this space were reportedly doubling revenue every three to six months as of mid-2026, which lines up with Mercor’s own jump from $1 billion to $2 billion in annualized revenue in just four months.
Frequently Asked Questions
Is Mercor legit?
Reviewers describe it as a real company that pays workers, though work is not guaranteed. It is also a highly valued, well-funded company, in talks for a $20 billion valuation as of mid-2026 with roughly $2 billion in annualized revenue.
How much does Mercor pay?
One review reports from about $12 to over $200 per hour depending on expertise.
How often does Mercor pay?
A review reports weekly payments.
Is my data safe?
Mercor had a data breach in March 2026 caused by a supply chain attack on the open-source tool LiteLLM, affecting a subset of its nearly five million experts. Share only what you must and read the privacy terms, and check whether you were among the notified individuals if you have an account.
Is it a full time job?
No. It is contract work.
Who owns Mercor?
Mercor was founded by three cofounders who were all 23 years old as of 2025: Brendan Foody and Adarsh Hiremath as co-CEOs, and Surya Midha as board chairman, backed by investors including Felicis Ventures, Benchmark, and General Catalyst.
How does Mercor compare to Scale AI or Surge AI?
Mercor, Surge AI, and Handshake AI all compete for the same pool of credentialed experts doing RLHF and reasoning work for AI labs, with hourly rates in a broadly similar $50 to $200-plus range depending on expertise. Scale AI is an older, more established player that built its business on broader data labeling and annotation before expanding into expert-level work, while Mercor has grown faster on the expert side specifically.
Why are Mercor’s founders so young?
Brendan Foody, Adarsh Hiremath, and Surya Midha founded Mercor in 2023 while still in their early twenties, having met on their high school debate team. Their rapid rise to becoming self-made billionaires by October 2025 reflects how fast the AI training data market itself has grown, not just their individual company.
Final Verdict
Mercor can pay well for real expertise, and it is backed by real revenue and major investors rather than being a fly-by-night operation. Income is still uneven and privacy matters given the 2026 breach, so read the terms, limit what personal data you share, and keep your main income separate.
