Warning to Contractors About This Company’s Unpaid Work Practices
This company used my work to submit to its client just to ensure timely delivery and meet deadlines. After that, they emailed me saying my contract was terminated and my payment was withheld. From what I’ve seen, this same situation has happened to hundreds of contractors.
After receiving the termination notice, I reached out to the CEO, Phoebe Yao. I am quoting exactly what she wrote back to me:
“Oh yea that's no good. Well we can see based on the quality if we used your work i think it's fair to compensate.”
I am 100% certain they used my work and delivered it to their client, yet they still didn’t pay me. When I tried contacting the CEO again, she told me to reach out to one of her employees instead. She avoided everything she had previously said to me.
If you’ve experienced the same, don’t stay silent, let the world know what happened to you.
They hire remote contractors who are mostly non-US based, and their contract requires any disputes to be handled under U.S. legislation. They clearly take advantage of the fact that most contractors outside the U.S. cannot realistically fight back. They can silently withhold your hard-earned money. Payments are also consistently delayed for weeks even though they promise weekly payouts. There are always excuses, such as “QA is taking longer than expected” or “issues with the payment method,” etc.
They lie about paydates
I'm publicly documenting my experience as a contractor with Pareto.AI for other professionals to reference.
Timeline:
Tuesday: Promised payment 'Friday at the latest'
Completed all work under payment urgency pressure
Friday 4:35pm: Corporate deflection, no payment, now impossible until Monday due to ACH processing
Issues:
Systematic payment manipulation (using payment urgency to extract work, then delaying payment)
Breaking documented commitments to contractors
Cutting contractor access before processing payment
Corporate gaslighting when confronted with timeline violations
This contradicts your public positioning as an 'ethical AI platform' and 'talent-first' company. The documentation of these practices is being shared with industry partners and regulatory bodies for review.
Other contractors should be aware of these systematic payment issues when considering work with Pareto.AI.
Professional reputation in the AI industry depends on honoring commitments to the contractors who enable your business model."
LIES
LIES! LIES! LIES!
They advertise their service as a PER MONTH subscription when in actuality they lock you in for a whole year!
It means you'll be billed for the full price instead of a one-time only bill. This is scam in all but name!
As someone who was actually interested in their offers, I'll be forced to leave a REAL, LIVE review - a negative one at that!
Don't trust all the positive reviews: they're all fake.
Fitting for them.

The best AI training company out there!
I've been working with Pareto.AI as an AI trainer since January 2024. When I was first recruited, I was skeptical at first as I had never heard of the AI training industry, much less Pareto itself. Working with Pareto has completely transformed my views of the tech industry, and--having seen other AI training companies--I have no doubt that Pareto is at the top of the industry in terms of how they treat their workers. Many of their core values emphasize the priority of their trainers, and they really do mean it when they say that they provide industry-leading pay.
Having met the CEO--Phoebe Yao--and many other Pareto project managers and employees online, I can definitively say that their team is not only professional and top-notch but also super kind, attentive, and understanding. They have always listened to my concerns and feedback, and I have never felt like they were dismissive or that they didn't know what they were doing. I HIGHLY recommend Pareto.AI to anyone considering jumping into AI training work either part- or full-time!
Working with Pareto.AI has been a great…
Working with Pareto.AI has been a great experience for me. What sets Pareto.AI apart from other companies in the same field is not just their commitment to customers’ satisfaction, but also how they consider their employees’ well-being and interests. The company listens to its workers to ensure they are always comfortable and willing to provide the best services possible. In addition, the company has shown efforts to bring onboard professionals from different regions worldwide possessing diverse ideas and talents, which contributes to its competitiveness and customer satisfaction. I highly commend the company for its good work.
Setting the industry standard
The Pareto team has the world's top Prompt Engineers and AI trainers eager to take on any project and deliver quality work. I can confidently say that they repreesent the industry standard and for this, I highly recommend them.
Two thumbs up!
Outstanding
At Pareto.AI, labelers are valued far beyond being just another group of workers. The company demonstrates great consideration for its labelers, actively listening to their needs and embracing individuals from diverse nationalities, genders, ethnicities, and races. Pareto.AI celebrates their contributions and actively promotes inclusivity, ensuring everyone feels appreciated and respected.
They do what they say they'll do

Great service
Great service, we hired Pareto to help us create an investor database for our reach out campaign. We were able to start and finish our project very fast, within 1 week we had the list ready. The quality of results is also fantastic!

Great women-led company
Pareto has a warm, helpful team that gets things done. They're fast, responsible and easy to work with on data-related projects. Highly recommend for SMEs and startups who don't have enough time to do it all!
Getting things done!
At my startup we were facing many manual challenges and we needed some help in an scalable way. A friend of mine recommended me to check out Pareto and I invited them to participate in a tender for the project which they won. Right away they took over the tasks in a very professional way, their learning curve was very fast and we almost went in "automatic pilot" with them. The team at Pareto is very professional, they have attention to detail and you can trust them. They are an only woman team, empowering single moms to get a good job opportunity, this is something I really liked, because of its social impact. Invoicing and payments are very easy to do. I just love the way they work, very very recommendable!
Highly Recommend!
Pareto is quick to respond and delivered high quality work. They never missed a deadline and always followed up with questions if they had any.

Pareto is a great company to work with
Pareto is a fantastic company; always incredibly diligent, responsive, and attentive with their work. The majority of tasks my team assigns them involves sourcing and outreach, which Pareto continues to complete to an excellent degree. Furthermore, there have been a few instances where my team has assigned some very last minute, urgent tasks, and Pareto has been able to consistently deliver.
Above all, they always have a great attitude, so it's a pleasure to work with them.
The Pareto team is amazing!
The Pareto team is fast, responsive and diligent. They took my requests and executed them perfectly.
