Disclosure: This article contains a referral link to Mercor. If you apply through it, we may earn a reward at no extra cost to you. It does not affect how we evaluate the platform — the caveats below are here on purpose.
Mercor is the kind of platform that sounds too good to be true until you check the funding rounds: a San Francisco company valued at $10 billion, counting OpenAI, Anthropic, Meta and Google among its customers, paying doctors, lawyers and engineers to train AI models. And yes — Mercor is legit. The part nobody tells you up front is that getting accepted does not mean getting work. And work, when it comes, can dry up just as fast.
This Mercor review covers what the platform actually is, how its AI hiring process works step by step, what experts genuinely earn on it (with real reported ranges, not promises), and the honest downsides — including a serious 2026 data breach — that you should weigh before uploading your documents.
The short version: Mercor is a real, well-funded AI talent marketplace with some of the highest hourly rates in AI training work. Getting in means a recorded AI video interview and an algorithmic score, after which clients can find you directly. Earnings are project-based and unpredictable, so treat it as side income, not a salary. If you are a subject-matter expert with genuine credentials, it is worth the application. If you need steady work, it will not give you that.

The short answer: is Mercor legit?
Yes. Mercor is a real company — founded in 2022 by three Thiel Fellows, headquartered in San Francisco, and reported at a $10 billion valuation after a $350 million Series C led by Felicis in October 2025. Its contractor base includes doctors, lawyers, scientists and senior engineers, and the company pays out over $1.5 million a day to more than 30,000 contractors, according to industry reporting.
But “legit” and “worth your time” are different questions. Here is this Mercor review at a glance:
| Area | Verdict | Why |
|---|---|---|
| Pay rates | Strong | Among the highest in AI training work, especially for coders and domain experts |
| Hiring process | Fast but impersonal | A roughly 20-minute AI video interview and algorithmic scoring — no human recruiter |
| Work availability | Unpredictable | Verified does not mean busy; projects come and go without warning |
| Privacy | Caution | A March 2026 data breach exposed contractor data; lawsuits are ongoing |
| Referral programme | Solid | A share of your referral’s earnings, with clear rules |
So: real platform, real money, real caveats. Worth an application if you have genuine expertise. Not something to plan your bills around.
What Mercor is and how it works
Mercor connects subject-matter experts with AI labs that need human judgement to train and evaluate their models. The work looks like ranking AI answers, reviewing code, fact-checking outputs, and bringing real domain knowledge — how a lawyer reasons, how a doctor thinks — into the training loop.
Originally built as a recruiting platform for freelance programmers, Mercor pivoted to the bigger opportunity: frontier AI labs all needed the same scarce thing — smart humans. OpenAI, Anthropic, Google DeepMind and Meta now sit among its customers.
You work as an independent contractor: fully remote, on your own schedule, paid hourly for tracked work. No benefits, no employment contract — you are a freelancer with a sophisticated client.
Domains in demand include software engineering, medicine, law, finance, physics, and general AI evaluation work. You do not need a famous university, but the bar is real: most projects expect undergraduate-level expertise at minimum, and many require years of professional experience or an advanced degree.
How the Mercor hiring process works
The application is designed to be done once and reused:
- Pick a listing. The job board carries thousands of roles, from “Generalist Expert” to specialised engineering and medical roles, searchable by keyword.
- Create your profile. Upload a resume (a text-based PDF works best) and fill in your background. A complete profile matters, because the matching system uses it to surface you to clients later.
- Sit the AI interview. A recorded, roughly 20-minute video interview with an AI interviewer that asks questions based on your resume and the role, follows up on your answers, and — for technical roles — watches your screen while you solve a problem. You can retake it up to three times from your dashboard.
- Get scored. An algorithm scores you, not a human recruiter.
- Become a Verified Expert. Score well and hiring managers can find you and send offers directly. You do not re-apply to every role; the one application carries over.
That last part is the genuinely useful bit: once you are in the pool, new matches can come to you. The catch, reported consistently by contractors, is that selection is competitive — plenty of applications come back “not selected”, and Mercor matches you to specific client contracts, so being verified does not mean constant offers.

What experts actually earn on Mercor
Mercor sits near the top of the AI training pay scale, but the range is wide and depends entirely on your domain and credentials. The figures below are reported in independent reviews of live Mercor job boards — they are real ranges, not promises. The board changes constantly and rates vary by contract:
- Entry-level AI training roles (e.g. AI Model Specialist): around $16/hour
- Data Annotation Specialist roles: around $50/hour
- General expert contracts: around $70/hour
- Engineering roles: $70–$200+/hour
- Specialist consulting and data science roles: $150–$220/hour on the live board
- Reported average across contractors: about $85/hour
Mercor pays weekly, typically through Stripe (or Wise in countries Stripe does not cover), and the earnings dashboard tracks your total to date. There is no fee to join — Mercor takes its cut from the client side, reportedly around 30% on placements.
Two things to keep in mind before the numbers excite you. First, high rates per hour say nothing about hours per week — a $200/hour contract that runs for ten hours is a nice bonus, not a living. Second, these are gross contractor earnings: you handle your own taxes, and there is no holiday pay, health cover or pension.
Mercor review: the honest caveats
No honest Mercor review skips these:
Work is unpredictable. The most consistent contractor complaint is that verified status does not mean steady work. Projects appear and dry up with client demand. Treat anything you earn here as a bonus on top of real income.
A data breach in March 2026. Mercor was caught up in a supply-chain attack through a poisoned open-source library, and contractor data was exposed — reporting puts it at around 40,000 affected people and 4TB of data, with an active investigation and a class action filed. Uploading your ID and resume means trusting a company that has had a serious security incident. Weigh that before you apply.
You are scored by an algorithm. The AI interview and algorithmic scoring feel impersonal, and you may never speak to a human at Mercor. Some people find the recorded interview uncomfortable; others retake it until it lands.
Independent contractor, full stop. No benefits, no guarantees, no severance. You handle taxes and admin — a simple CRM helps keep multiple projects straight once offers start landing.
Not available everywhere. Mercor requires phone verification, and SMS verification does not work in 100+ countries. Check eligibility before investing time in the application.
Selection is competitive. Contractors report plenty of “not selected” outcomes. Getting into the pool is a start, not an offer.
Mercor vs the alternatives
Mercor is not the only platform paying experts for AI training work. Two worth knowing:
- Alignerr works similarly — an expert network matching specialists with AI labs for training and evaluation projects, with its own acceptance process and pay bands. We are publishing a full Alignerr review soon; the model is close enough that whichever platform matches your domain first is the one to take.
- Micro1 is another AI hiring platform in the same space, focused on AI-interviewed roles with referral-driven hiring — also on our review list.
The practical advice from contractors is not to pick one platform and wait. Apply broadly, keep your profile complete, and treat whichever one offers matched work first as the winner. None of them replaces steady income. Many contractors also build a simple personal page to look credible to clients — our landing page builder comparison covers the cheapest ways to do that.
Who should apply (and who should skip)
Apply if you:
- Have real, credentialed expertise in a domain AI labs pay for (engineering, medicine, law, finance, science)
- Want flexible side income and can tolerate unpredictable project flow
- Are comfortable being interviewed by an AI on video
- Understand you are a contractor — no benefits, no guarantees
Skip (for now) if you:
- Need predictable monthly income
- Are uncomfortable with algorithmic scoring and recorded interviews
- Live somewhere Mercor’s phone verification does not support
- Want full-time employment rather than project work
Frequently asked questions
Is Mercor legit?
Yes. Mercor is a real, funded company — founded in 2022, valued at $10 billion after a 2025 Series C, with OpenAI, Anthropic, Meta and Google among its customers. It pays contractors weekly. But it is a competitive, project-based marketplace, not guaranteed employment, and a 2026 data breach means you should read the privacy terms before uploading documents.
How much does Mercor pay?
Reported rates range from around $16/hour for entry-level AI training roles to $150–$220/hour for specialist consulting and data science contracts, with an average near $85/hour. Rates vary by domain, contract and time, and project availability is unpredictable.
How does the Mercor AI interview work?
You complete a recorded, roughly 20-minute video interview with an AI interviewer that asks questions based on your resume and follows up on your answers. Technical roles may include screen-observed problem solving. An algorithm scores you, and you can retake the interview up to three times.
Do you need a degree to work on Mercor?
Most listings expect undergraduate-level expertise at minimum, and many projects require years of professional experience or an advanced degree. The bar is highest for specialist medical, legal and scientific roles.
Is work on Mercor guaranteed once you are accepted?
No. Becoming a Verified Expert means clients can find you and send offers, but contractors consistently report unpredictable availability. Apply to multiple roles, keep your profile complete, and treat Mercor as secondary income.
