In short

The episode is about a fast-growing “gig work” category where people are hired to talk to and train AI systems to perform specific white-collar jobs. It focuses on Mercore, a 2023 startup founded by three college dropouts that acts as a middleman between AI labs and human contractors; it says it serves clients including OpenAI and Anthropic and pays experts over $3 million/day. Guest Carolina Perez-Sanz, a Spain-born, multilingual former speech-language pathologist, became a Mercore “writing analyst” after LinkedIn outreach for Portuguese writing. She helped correct European vs Brazilian Portuguese, flag AI “AI-isms” in creative prompts (e.g., clichéd “Tuesday” patterns), and improve human-like writing. Key claims include rapid model learning (her job ended quickly), contractor mixed feelings, disputes over IP ownership, and privacy concerns after a Mercore data breach.

Notable examples

European Portuguese phrasing corrections; memoir prompt output that inserted obvious “Miami Beach” sand details; lawsuits alleging screenshot/biometric data exposure.

0:05Ryan Knutson:There is a new type of gig work that's growing rapidly right now. It involves talking to AI and teaching it how to do your job. There is this new sort of category of jobs that basically involve people sitting in front of a computer and helping to train AI to perform some of the things that they are, you know, experts in or what they used to do in their careers, pretty much. Our colleague Katie Bentley covers tech, and she's been reporting on a startup that's doing this kind of work. And it's hiring like crazy. It's called Mercore. The best ways to sort of get insights about this type of work is to just look at the job postings that are available.

0:51They put out a gazillion postings on LinkedIn.

0:55Ryan Knutson:Like, can we look at some of their LinkedIn posts? Ooh, let's. Okay. So you'll see tons of posts. Start your month with work from home. Explore flexible remote opportunities with Mercore and work from anywhere. Apply here. It'll basically say, like, we are looking to hire someone with experience as, you know, an investment banker, entry-level analyst, or whatever. And it lays out specifically what they're looking for. And I think the idea is to help the AI perform the duties of those roles. Are they ever looking for podcast hosts? I've seen ones for, like, voice actors and stuff. I mean, the range of job postings, it's, like, hard to think of jobs that they're not hiring for.

1:34I mean, they were looking for dermatologists, radiologists, therapists, like accountants, consultants, actors, I mean, screenwriters, all kinds of things.

1:48Ryan Knutson:Is there a metaphor that you could use for like this phase of AI training? Like the first phase of training AI is like reading every book in the library. Yeah. And so now going to sit down with a tutor, maybe? Yeah, I think actually a tutor is like a really good way to put it. It's certainly like moving us toward the direction of AI being able to handle more and more complex sort of white collar work related tasks. Welcome to The Journal, our show about money, business and power. I'm Ryan Knudsen. It's Thursday, June 4th.

2:30Ryan Knutson:Coming up on the show, the new gig work that's training AI to take your job.

3:51Ryan Knutson:Mercore was founded in 2023 by three college dropouts. It's become a$10 billion company in less than three years. It's basically a middleman between large AI companies and humans who can help train large language models. AI companies need a lot of data in order to improve their models. And the gist is that, you know, most, if not all, of the publicly available data has already been used. So in order for the AI to get smarter, if you will, it needs fresh sources, fresh materials to train on. And humans turn out to be very good sources of that. Mercore has clients. Their clients have included some of the biggest AI companies, including OpenAI and Anthropic.

4:37And so they're serving as sort of this go-between, and Mercore hires the contractors. And so then the contractors are the ones who are helping to improve the models.

4:48Ryan Knutson:One person who's worked as a contractor for Mercor is Carolina. I'm Carolina Perez-Sanz. I'm originally from Spain, from Madrid. I grew up in three languages, right? So my parents are from Spain, but we lived in Lisbon. So my friends were Portuguese. And then I went to a French school. So I grew up in three languages simultaneously. And I was always very interested in words. Carolina came to the U.S. over a decade ago, went to graduate school, and spent a big part of her career working as a speech and language pathologist. So what I did was I helped people for whom voice was their main job instrument, if you want.

5:35So I helped journalists, reporters, TV and radio presenters, actors, singers, lawyers, everybody who needed to have a voice that sounded powerful.

5:54Ryan Knutson:Recently, while trying to grow her business, she started promoting her language and writing skills on LinkedIn. And it led her to a job she wasn't expecting, training AI. This was March 2025. I was to attract clients on LinkedIn, posting, etc. And because I had on my headline that I spoke Portuguese, Portuguese, Spanish and English, somebody from an agency called Mercor approached me because they were looking for Portuguese speaking writers. The pitch is, you speak Portuguese, do you want to apply for a writing analyst, bilingual in AI? And I said, oh yeah, having a title that says writing analyst sounds fun.

6:50What attracted me was to have the writing analyst in my job title. In reality, I always wanted to be a writer, but I thought I could never make a living being a writer, so I never tried.

7:05Ryan Knutson:Mercore told Carolina that she would be assigned projects with major AI companies, and that she'd be using her skills to train their large language models. Like most Mercore contractors, Carolina signed an NDA that prevents her from revealing the name of the client she worked for. I thought, well, okay. Okay, why not? I'm going to be paid. The pay was not bad at all. How much was it? $45 an hour. How did you feel about that as a job, to just train AI systems? In the beginning, I felt great because I thought to myself, oh, I'm in the cutting edge of technology. I know things that most people don't and things like that.

7:45And it was really interesting.

7:50Ryan Knutson:For contractors, being on the cutting edge of technology means trying to make the AI models good at the things they're good at. For Carolina, the task was to help it improve language and writing skills. Her first project was simple. The client asked her to evaluate how well the AI was responding in European Portuguese as opposed to Brazilian Portuguese. The task in the beginning was to make sure that the written responses that the models gave included phrases that were commonly said. And because I was doing European Portuguese, if the response I got had a lot of Brazilian Portuguese type of phrasing, I had to correct it.

8:34I would click on a task and I would see the prompt and then the response. And I had to say, well, this response doesn't match the prompt well because they were speaking with a lot of Brazilianisms. So I had to adjust and say, no, in Portugal, we don't speak like this. We say it like that or whatever.

8:58Ryan Knutson:Beyond just catching simple language errors, Carolina also worked on projects that involved teaching AI to write and speak more like a human. We needed to create prompts to give us creative writing outputs. So if I want to write a memoir, I remember one of the prompts that I wrote was write the opening scene for a memoir where a woman lives in Miami Beach. And it makes so obvious choices that it said, yeah, I was lying on the floor and there was sand everywhere. Like the fact that you live in Miami Beach doesn't mean that you live on the beach. And there's going to be sand in your apartment. Exactly.

9:48So those were the things that I needed to flag. And sometimes at the first reading, the first pass was, yeah, okay, it's not bad. And then, like, wait, this doesn't make any sense. Why is she lying on the floor?

10:04Ryan Knutson:Yeah. As the projects went on, and she kept training the AI to sound better, Carolina said that she and her fellow contractors got really good at catching all the cliches and patterns that the AI needed to work on. We had a Slack channel. There were a lot of screenwriters, playwriters, literature professors, historians, and we started to notice AI-isms. Like, oh, AI does this all the time. What kinds of things is an AI-ism? At some point, everything happened on a Tuesday. Oh, really? Because they want to, they have learned in creative writing 101 for AI models, they have learned that you need to write specific things and land everything in real life.

10:55So they say, it was a Tuesday and everything was a Tuesday.

11:00Ryan Knutson:The most average of days. Exactly. And that's exactly what I thought. Like, why would Tuesday be more average than Wednesday? Like, it was interesting. Our colleague Katie spoke to a lot of contractors like Carolina. And she says they have mixed feelings about this type of work. Not everyone is, like, so psyched to be doing this. I think they, in some cases, they just can't find work. And this is a way to make some money. And there also is, there was this sort of sense of inevitability that I think they all felt of, like, I mean, look, the whole question of, like, how many jobs will AI automate away?

11:38super nuanced, complicated topic that nobody really knows the answer to. Right. But among these workers, they kind of feel like, okay, writing's on the wall, that at least some of the stuff I used to do is going to be automated. So I'm not going to be able to prevent that. So why don't I just make some money kind of on the way out, I guess?

11:58Ryan Knutson:It's an interesting thing to do, I feel like, as a gig if you're out of work in that industry, because it's almost like you're burning down the building behind you, you know? Like, if I can't get a job in this industry, nobody can. Yeah, I mean, people I spoke with said as much. Mercor said in a statement that training AI is becoming one of the fastest-growing categories of work in the economy. The company said, quote, We are paying experts more than$3 million a day for that work. The company added that every major technology shift has looked like a jobs crisis, but the consistent pattern is that it creates new categories of work.

12:35Ryan Knutson:coming up how some of more course tactics have landed it in hot water

13:50Ryan Knutson:One thing that happens at Mercore that can make contractors uncomfortable is that they're sometimes asked to share prior work. The trouble is, much of their prior work could technically be owned by a previous employer. Their responsibility to the client is to be helping to make these models capable of performing more sophisticated work. And that in order to do that, in that sense, what you need is sort of people with prior work materials. The issue there is that there is a ton of prior work material people have, but they don't tend to own the rights to it. And so then you get into some of the stuff that I reported on where Mercore was approaching, in this case, it was visual effects artists.

14:35They were messaging them on LinkedIn and saying like, hey, we're looking to purchase high-end production work such as, quote, 4D physics scenes with camera data, depth and motion point tracking. And the guys I spoke with who had been approached were very taken aback by this request because even though they're contractors, the work they had done was for major studios. They said they sign NDAs that are like the thickness of a book and everything's under NDA. It's all protected IP. So they were very taken aback by Mercore offering to purchase this data and work product because they were like, dude, we definitely don't own this stuff.

15:12Ryan Knutson:What has Mercore said about this? So Mercor said that they do not buy intellectual property and that they license content directly from individuals and only when they own it. They also said that they do not ask for nor do they want material owned by a current or past employer. So they're saying we only want stuff that people actually have the rights to license us. Another issue came to light after Mercor was hit by a big data breach. They suffered a large data breach recently, which, to be fair, many, many, many startups suffered a breach around the same time. After the breach, Mercore was hit by at least seven class-action lawsuits.

15:58Ryan Knutson:They alleged that Mercore exposed contractor information, ranging from recorded job interviews to facial biometric data and screenshots of workers' computers. Within the claims of the suits were a lot of really interesting allegations about the ways in which the company allegedly acquires the data that it uses to serve its customers. So for one thing, this is sort of interesting, is that the contractors, their computers, while they're doing their work, Mercore has software that takes screenshots of their work. And so among the allegations were that those screenshots were shared with the clients and sort of part of the data that they were handing over to the clients.

16:41Ryan Knutson:So essentially like watching the employees work and seeing what they're doing on the computers is a form of data that's being used to train AI, potentially. That's what the allegations are in the suit. And, you know, Mercore makes the point that like we tell people that you are only to be working on your Mercore-related projects when you're billing for time. So like, if you have two monitors, you should only have your Mercor-related work up on either screen at any time. Mercor said they strongly dispute the speculative claims in these lawsuits and they look forward to presenting the facts at the appropriate time and place.

17:17And they also added that they take the privacy of their customers, contractors, employees, and those they interview seriously and comply with relevant laws and regulations. Yeah, so that was their response to some of the reporting and the allegations included in these claims.

17:31Ryan Knutson:Still, Mercor is continuing to attract contractors who want to get paid to train AI. Last year, the company hired 30 ,000 of them. And it's also attracting a lot of investors, too. The company, they've raised quite a bit of money, and it was in the fall that they had a new funding deal that valued them at$10 billion, and that actually was five times what they'd been valued the February prior to that race. So they've been one of those sort of, you know, quickly rising companies. The startup also has competitors now like Handshake AI, Micro One, and Surge that connect AI companies with contractors looking for AI training gigs.

18:10Ryan Knutson:How long do you think companies like this will need to exist though? I mean, isn't the whole point to train AI so that it's capable of doing everything? So won't theoretically Mercor succeed so much that it no longer has a reason to exist? I mean, I think that these are big, important questions. There's so much uncertainty with respect to what AI's capabilities will be. What will the cost limitations be? The resource limitations? I mean, there's, I think sort of my takeaway is that the ambitions of the companies are limitless. This is basically what happened at a smaller scale to Carolina. She only worked in MerCorp for about a year.

18:49Ryan Knutson:After her first assignment, that one where she had to flag Brazilian versus European Portuguese. She was surprised at how fast the AI was learning. That's when I worked myself out of her job because the model learned so fast. So with all the data that we were inputting, like in a week's time, you didn't have to correct anything. Like the prompt and the response were perfect. Nothing to correct. And so you'd look at it and be like, oh, yeah, that's pretty good. That's pretty good, but on the other side, I didn't have a job anymore. After a few more projects with Mercore, she started to have more negative feelings about the work and about AI itself.

19:31I started to think my job is actually making this more of a monster. We're like just putting out pollution out there. And what is it doing to the culture, to the society? I thought it was really like a waste of talent, a waste of time. Not for me, but a waste of collective time. Like we're not connecting people to people. So, yeah, I started to feel very like disillusioned.

20:06Ryan Knutson:Tell me about when you made the decision to quit. Well, actually, because. So this is the thing. I needed the money. And I decided to quit when the money was really like the last project I did instead of$45 an hour, they would pay$35 an hour. And then the very last one that I did, they were paying by the task and the pay was something around$20 per task. And I thought, this is ridiculous. So I did five tasks and I quit because I didn't think it was worth it. Recently, Carolina got a new job. She now goes door to door talking to humans as a salesperson. It's still an open question as to whether AI will be capable of doing people's jobs and to what degree.

21:07Ryan Knutson:but what this story tells me is that these AI companies are coming for you. Like they're trying. Yeah, totally. You know, whether or not they're going to succeed or not is an open question, but like they're trying to make AI good enough to do it. Yeah, no, I absolutely, you know, that's definitely was one of my takeaways as I've been reporting on this and talking to all these people about the type of work they do. I don't really see evidence that they're like, well, no, we shouldn't automate that type of white collar work. it feels pretty sweeping.

21:46Ryan Knutson:That's all for today. Thursday, June 4th. The Journal is a co-production of Spotify and The Wall Street Journal. Additional reporting in this episode by Angel Aoyoung.

21:59Ryan Knutson:Thanks for listening. See you tomorrow.

22:05Thank you.

From the publisher

There’s a new gig economy that involves training AI to do white collar jobs. And one company, Mercor, is leading the charge. The training startup hired 30,000 contractors just last year to help AI companies get their models trained up on sophisticated roles. Ryan Knutson spoke to one former Mercor contractor about the job and WSJ’s Katie Bindley lays out the tactics that have landed the startup in hot water.
