Is Mercor Legit? Pay, the 2026 Data Breach, and Lawsuits

What Mercor Is and Who Is Behind It

Mercor is a San Francisco company that matches professionals to paid AI training and evaluation projects. Brendan Foody, Adarsh Hiremath, and Surya Midha founded it in 2023, and its customers are AI labs and large companies. Fortune's April 2026 reporting named Anthropic, OpenAI, and Meta as Mercor customers, though it did not confirm what work each one buys.

The funding has moved fast.

Mercor's own announcement says it has "more than five million experts in our network getting paid to train frontier AI models" and names Benchmark, Felicis, General Catalyst, NVIDIA, Salesforce, and Zoom among the Series D investors. Dealroom reports an annualized gross revenue run rate of $2 billion in June 2026. That is a run rate, not audited revenue.

Five million is a network size, not a job count: the live board holds 325 roles. And the money comes from AI labs buying data and evaluations, so your work lasts exactly as long as a customer's project does. That is why projects ending quickly is a recurring complaint in r/mercor_ai, a community of roughly 48,000 members per GummySearch.

Is Mercor Legit? What the Reviews Show

Short answer: yes. The company is real and well funded, and the payment complaints that fill other platforms' review pages are rare here. What shows up instead is silence after applying, and projects that end early.

Trustpilot's praise is about pay. The criticism is about ethics and silence:

"Best of all, the pay is great, reliable, and always on time." (Jenni M., 5 stars, May 17, 2026)

"The support is very quick and efficient" (Marcus Lozano, 5 stars, October 26, 2026)

"I really do not recommend this platform and it felt unethical." (Viktorija Medeina, 1 star, November 5, 2026)

"I didn't even receive any kind of response from the team even though I have reported it." (Adarsh, 1 star, November 6, 2026)

On Reddit, workers who say they landed contracts mostly report being paid on schedule through Stripe. I couldn't open Reddit threads directly, so this summary reflects thread excerpts surfaced through search, not a systematic count. The unhappy threads are mostly about hearing nothing after the AI interview. Others describe projects that ended after a few days or a week, usually with pay received for the time worked, and referral bonuses that came in below the headline figure. A few posts ask whether Mercor is collecting data under the cover of job listings. Those are questions and allegations, not findings.

Both sources lean. Trustpilot reviewers are probably weighted toward people who got work, and Reddit referral threads are partly written by people who earn from referrals. Neither is a controlled sample.

The 2026 Data Breach and the Lawsuits

This is the part most "is Mercor legit" pages skip, and it should weigh more on your decision than the Trustpilot score.

In late March 2026, Mercor was hit by a supply chain attack on LiteLLM, an open-source tool that connects applications to AI models. Mercor's own account, posted June 25, 2026, says that of its nearly five million experts only a "very limited subset" had sensitive information affected. It gives no number and says no employee data was affected:

"There is no evidence that any of this data has been used fraudulently." (Mercor, June 25, 2026)

Press and lawsuit claims are much larger. Fortune reported on April 2, 2026 that the extortion group Lapsus$ claimed up to 4 terabytes of data, including source code and database records, and posted apparent Slack data and two videos of conversations between Mercor's AI systems and contractors. Mercor did not answer Fortune's specific questions about those claims. A class-action complaint, as summarized by law-firm and tracker sites, alleges contractor identity documents and interview recordings were among the data. Treat the scale as disputed.

Mercor mailed breach notices on June 25 and 26, 2026 with an offer of TransUnion identity protection, so check your inbox if you were an expert before April.

Meta paused its work with Mercor after the breach, according to a Meta spokesperson quoted by the Business and Human Rights Resource Centre.

What to do with all that:

• Allegations are not findings. I found no verdict in any of these cases.
• Identity verification is not optional. Mercor's payments page says it can't be skipped, and US workers must supply an SSN. Decide whether you are comfortable handing that over before you start.
• Check your contract type. Of the 325 live listings, 48 describe a W-2 position through a staffing company, one mentions 1099, and the rest don't say. The misclassification suits are about exactly this question.
• Use a password you don't reuse, and keep any ID scans you upload to the minimum the platform asks for.

What Mercor Actually Pays

The live board shows a median advertised range of $60 to $90 an hour, but the spread by field is wide. As of November 10, 2026, Mercor's public listings feed had 325 active roles, 309 of them remote. Of those, 304 are hourly with a stated range, 11 are paid per task, 7 are one-time payments such as paid research surveys, and 3 are yearly.

Medicine is the outlier. Every other field's median range sits between $48 and $122. Another 41 hourly listings carry no field tag and have a median range of $70-$90. These are advertised ranges, not what any one person is offered, and I calculated the medians from the feed myself.

Hours are not guaranteed either. 148 of the 325 listings state a 40-hour week, 54 state 20 hours, and 88 state no weekly hours at all. 82 are "evergreen" postings that stay open continuously, which means they are talent pools as much as openings.

Rates also change on running projects. In November 2025, Forbes reported that Mercor ended a Meta data-labeling project called Musen, which at its peak involved more than 5,000 contractors, and offered a replacement project, Nova, at $16 an hour against $21 before. Mercor called the claims inaccurate and said all roles are temporary and project-based.

How and When You Get Paid

Mercor pays hourly contractors weekly. Per its payments page, payouts go out every Wednesday around 12:00 PM Pacific for the previous Saturday-to-Friday week, with the week measured in Indian Standard Time.

Contracts are in US dollars and your provider converts at payout. The docs disagree slightly on arrival: the time-tracking page says most funds arrive Thursday, while the payments page says up to five business days at Stripe's default speed. If you use Wise, you must accept each transfer email or the payment stalls on Wise's side.

The pay comes with tracking. Mercor requires the Insightful desktop app for hourly work.

"Insightful is the official time-tracking tool required for Mercor projects." (Mercor talent docs, Time Tracking and Pay Policies)

Insightful "may take periodic screenshots to confirm you are working", and a person reviews screenshots and activity logs before any pay is withheld. Hours not tracked by Friday 11:59 PM IST aren't eligible for pay, manual adjustments need documentation and "are not guaranteed", and time logged while a contract is paused isn't paid. Hours can be withheld for policy violations, spam or bad-faith activity, or logging time without doing project work. Disputes have to be filed in the next pay period, and the docs say:

"Dispute resolutions are definitive." (Mercor talent docs, Time Tracking and Pay Policies)

That tracking is also what some of the lawsuits above are about, so read the consent screen before you install it.

Getting In: The AI Interview, the Paid Trial, and Referral Fine Print

Most applicants do an AI-led interview and, for many roles, a paid work trial. Reddit posters say the interview is real and built around your resume, and a little odd to do with an AI. The work trial is documented on Mercor's own site:

• It is a single paid assessment, and you are paid for only one trial even if you receive several offers.
• A typical trial takes four to six hours and can be split across sessions.
• Each trial has a fixed payout shown on the trial page. Payment is typically processed within 14 business days of review, and funds arrive 3 to 7 business days after it shows as Paid.
• Payment depends on a complete, good-faith submission, not on being selected. Mercor can withhold payment for low-effort or incomplete work.

The weak spot is feedback:

"Unfortunately, we are unable to provide individualized feedback on your performance." (Mercor talent docs, Work Trials)

Your country decides a lot here. Of the 325 live listings, 105 (32%) are restricted to the United States by the eligibility field or the location text, and 20 list other specific countries. The other 200 state no country limit in the feed, though some say things like "Western Europe preferred". If your country is not listed, apply anyway but expect fewer matches.

Projects can also end abruptly. Mercor's contracts page says a deliverable-based contract "may be rendered void without further notice" if the customer changes its plans, and it states no general notice period for ending a contract.

One more thing, since this page uses a referral link. Mercor's referral policy pays the referrer 20% of the referral's earnings, up to a cap of 4 times the referral's hourly rate, and the cap is set by the first non-one-time offer the referral accepts. Work trials don't count. That is why headline bonus figures ("up to $X per hire") are ceilings, not typical payouts, and it matches the complaints in the referral threads on Reddit.

Apply to micro1 Too: How the Two Compare

Mercor's selection can end in silence, and its projects are temporary. About a third of its listings are also US-only. micro1 runs a separate pipeline with its own queue, so applying to both costs an afternoon, and a rejection from one says little about the other.

micro1 is also a real, well-funded company. Forbes reported on September 22, 2026 that founder Ali Ansari raised more than $100 million at a $4 billion valuation, and Dealroom says Ansari confirmed it. He also says micro1 passed a $1 billion annual run rate, a company-reported, unaudited figure.

micro1's own listings page doesn't render server-side, so the figures above come from an outside mirror and may lag the live site. Glassdoor reviews of micro1 as a contractor are split: one is titled "$6/hour basically a scam", another "Great contract work". Outside reviews treat the interview and the placement as separate hurdles: a good interview does not guarantee a paid project.

My read: if you are a US-based professional in medicine, law, finance, or software, start with Mercor, where the advertised rates are highest. If you are outside the US, or one queue stalls, start the micro1 application the same day.

Is Mercor Worth Your Time?

Is it legit? Yes. Is it safe with your personal data? That is a fair question after March 2026. Is it steady income? No: Mercor calls every role temporary and project-based, and its own contract page says a project can end without notice.

It suits people with a credential or professional experience who can handle a few weeks of uncertainty and don't mind identity verification or screenshot-based time tracking. It doesn't suit anyone who needs predictable weekly hours, or for whom the breach and the misclassification suits are dealbreakers.

Four rules I would follow:

• Treat the first month as setup time. The first Stripe payout is held for 7 days, and the work trial pays within 14 business days of review.
• Never pay anyone to get a Mercor role. A real platform pays you, and payouts go to a bank account in your own name.
• Apply only through mercor.com, work.mercor.com, or a referral link from someone you trust, and read the contract before you accept.
• Run a second platform in parallel. micro1 is the one we would start with, and our best AI training jobs roundup compares the rest.
