Welo Data
Welo Data is the AI training data brand launched by Welocalize (a 25+ year language services company), fielding a curated community of 500,000+ annotators, linguists, and domain experts across 155+ locales and 100+ languages (its site, read 6 Nov 2026). Workers take projects spanning data labeling, model output ranking, RLHF, human evaluation, red-teaming, and multilingual assessment. Its public Welo Global job board lists specific projects with location requirements and, where disclosed, role-specific pay. New contributors start at its AI Trainers site (aitrainers.tech, announced 27 Oct 2026, run on Welo Works), which leads to registration at app.welodata.ai (its Welo Works page, read 6 Nov 2026). Applying does not guarantee an assignment or a minimum volume of work.

Buying AI training data from Welo Data? Welo Data pricing for AI teams
Is Welo Data legit?
Researched Nov 2026 · 19 sourcesYes. Welo Data is the AI-data brand of Welocalize (founded 1997, now under Welo Global) and publishes how it pays, but expect unpaid one-shot tests and the risk of an unexplained account deactivation. Hours of unpaid, timed assessments with undisclosed pass marks, then possible permanent deactivation by its security screening with no reason given; Trustpilot reviewers describe both through October 2026. It pays $4–$55/hr by country; voice session directors to $80/hr (platform-stated).

Welocalize, a language-services company founded in 1997, launched Welo Data in May 2024 to supply AI training data, citing a community of 500,000+ experts. Since April 2026 both sit under a New York parent, Welo Global (CEO Paul Carr), which says it serves 2,000+ clients. Welo Data is run by Siobhan Hanna, formerly of Lionbridge AI and Telus AI; on 27 October 2026 it announced aitrainers.tech for new contributors, who invoice Welo Data, LLC in New York.
Freelancers get a purchase order for finished tasks (weekly by default, each Sunday), invoice it in Workday, and are paid 14 days after Welo Data receives the invoice, into Hyperwallet (wire in a few countries). US payees pay no Hyperwallet fees. US-based raters are part-time employees paid with a W-2.
Trustpilot (Welocalize page) 1.2/5 (103 reviews) · Trustpilot (Welodata page) 2.2/5 (8 reviews). Read November 2026.
Global: each posting names the country or language it hires for, from India and the Philippines to the US, Germany and Japan, and 41 of its 302 postings are on site, 39 in California and 2 in Seattle (its Lever board, read 6 Nov 2026). Its site cites 155+ locales and 100+ languages.
Its help center (edited 27 Oct 2026) lists mail from @welocalize.com, @welodata.ai and, while applying, @hire.lever.co; its aitrainers.tech safety page adds @weloglobal.com. Openings are on jobs.lever.co/weloglobal and, after sign-up, app.welodata.ai (read 6 Nov 2026); no fees. The help center says it never recruits by social-media message; the safety page says it may.
What people praise
- Contributors quoted on Welo Data's AI Trainers site praise flexible hours and say it pays on time (Welo Data chose these quotes).
- A reviewer who joined a Welo Data project in 2026 found onboarding organized and professional, and the mandatory training was paid.
What people complain about
- Applicants describe hours of unpaid, timed tests whose pass marks are never disclosed, with no feedback on results.
- Many say their accounts were permanently deactivated after sign-up or onboarding with no reason given, and support replied with templates.
- Some say jobs they qualified for vanished, projects showed as full, or they earned nothing months after passing tests.
- One reviewer says a completed project was never paid and support only resent payment instructions.
What has gone wrong
- October 2026. From August to October 2026, Trustpilot reviewers described Welo Data account deactivations after registration or onboarding. One quoted the October notice: the registration failed Welo Data's verification and security checks, no details could be given, and the account was permanently deactivated. Welo Data says its NIMO system blocks sign-ups using fake or stolen identities.
Best for: Bilingual and multilingual people, linguists and domain specialists in many countries who want flexible, task-based AI work and can pass strict timed tests. Not for: Anyone who needs steady hours or fast pay, can only work from a phone or through a VPN, or wants to see a test's pass mark or learn why an account was closed.
Honest catches
- Pay here is platform-stated, not measured live from a job feed, so treat it as a benchmark rather than a guaranteed rate.

What Welo Data pays
Platform-stated · as of 2026-11-06Researched rate card, platform-stated, as of 2026-11-06
No universal rate card is published, but about half the postings state pay. Read from Welo Data's own job board (Lever 'weloglobal', jobs.lever.co/weloglobal, its Welo Data - AI Services postings) on 6 Nov 2026: 302 postings, 105 stating an hourly rate in US dollars in the posting's pay field and 51 more only in their text, so 156 of the 302 state an hourly rate, set by country and language. Of the 119 remote ones, the middle pays $13 an hour and the middle half about $6 to $27 (a tenth $4 or less, a tenth $55 or more); counting only the 68 remote ones with a pay field, as on 29 Oct, the middle is $24. Maps relevance raters run from $3.30 (English, India) and $4 (Indian languages) to $20.30 (US, Canada), $22 (France), $24 (Germany, Hong Kong, Taiwan), $25.20 (Australia) and $29 (visual design, US); Ads Quality Raters from $2.40 (India) to $25 (Iceland) and AI data raters $5 (Madagascar) to $10 (Swedish), both in the posting text; language content reviewers $15 (Croatia) to $45 (Sweden); Hydrus voice contributors $20 to $65 and session directors $50 to $80; a Japanese PhD specialist $50 to $70. The lowest is a Dutch data annotator in Suriname at $2.25. 37 on-site projects in California (35 marked full time) pay $26 to $105 an hour, 4 video-recording projects $4 to $15 a session, 1 audio recording a fixed $32, and 3 postings state an annual salary in local currency; 138 state no pay. Its AI Trainers site shows sample rates of $10.89 to $20 an hour (aitrainers.tech, where welodata.ai/join-the-community redirects; read 6 Nov 2026). The live feed preserves each advertised unit; annual salaries and non-USD amounts are not treated as USD hourly wages.

How to get started on Welo Data
Researched Nov 2026Pick a role on Welo Data's job board (jobs.lever.co/weloglobal) or start at its AI Trainers site (aitrainers.tech), register at app.welodata.ai with your email and a unique phone number, complete that role's steps (screening questions, NDA and CV, timed assessments, an Okta login, learning modules and a client exam), confirm the job, and finish ID, tax and payment details before paid work starts.
Who can join
- A laptop or desktop computer: Welo Data does not allow work from a mobile phone.
- The latest Chrome or Edge, a stable connection and time for each timed assessment in one uninterrupted sitting.
- No VPN, proxy or similar tool while applying: they can interfere with eligibility screening and get an application declined automatically.
- One account per person: your phone number must be unique, and the profile details you confirm at sign-up cannot be edited later.
- For Ads and Search Quality Rater roles, nobody else in your household and nobody on your network: Welo Data does not allow applicants from the same house or sharing the same network.
- The language, location and hours each role asks for. For example, a French (Canada) annotator posting asked for C2-level French-Canadian, advanced English and at least 15 to 20 hours a week.
- For payment: a smartphone with a camera for ID verification, your tax ID number and a copy of your tax ID document.
- In Spain, Italy and Greece you must be registered as a freelancer.
Step by step
- 1
Find a role
Browse openings on its official board (jobs.lever.co/weloglobal) or, once registered, on the Opportunities page, where each shows the pay rate, expected weekly hours and a description of the work. Its AI Trainers site (aitrainers.tech) lists no openings itself, only five sample roles with rates, and its Apply button leads to registration (read 6 November 2026).
- 2
Register on the AI Trainers platform
At app.welodata.ai (where Apply on aitrainers.tech leads), enter your email, type in the one-time code it sends (only the newest code works), fill in your profile and confirm it. These details cannot be edited later, and incorrect ones can get your application rejected.
- 3
Answer the screening questions
Answer truthfully about where you live, your equipment and your experience. If an answer rules you out, only that opportunity closes, and you can apply to others.
- 4
Sign documents
Sign the NDA (and SLA) digitally and upload your CV. If you signed them for an earlier application, you do not sign again.
- 5
Pass the assessments
Take the role's timed assessments in Welo Works. You must pass every assessment assigned to your application, and you generally cannot retake one for 6 months.
- 6
Create your Okta login and study
Set up the Okta account used for WeLearn, Workday and logging back into the AI Trainers platform, then complete the learning modules, which can take up to 24 hours to appear.
- 7
Pass the client exam and confirm
Take the client exam, then confirm the job and its requirements. The job appears in your Jobs tab and the project team contacts you.
- 8
Set up payment
Verify your identity with a smartphone, verify your tax ID and submit your billing details and address. Validation takes from half an hour to two days.
Timed Welo Works assessments, then a client exam (per role)
Each role assigns one or more timed assessments, and you must pass all of them against a threshold the project sets and does not disclose; then come learning modules and a client exam. You can see your own score on the Certifications page of your profile, and the same result can qualify you for one project and not another. Public assessments, open to anyone, let you pre-qualify for urgent projects.
Format
Online and timed, in one continuous session on a laptop or desktop (latest Chrome or Edge). The timer starts when you open the assessment, including while you read instructions, and it submits automatically when time runs out or a rule is broken. Automatically scored results update within about 30 minutes; ones a person reviews can take up to a week.
How to prepare
- Use the study materials and learning modules first: Welo Data says the better you understand the learnings, the better your chance on the exam.
- Connect everything before you start (mouse, target-language keyboard, headset) and turn off notifications, messaging apps and updates: closing a pop-up after starting still counts as breaking a rule.
- Close every other tab and program, use one screen, and keep your phone away.
- Make sure your connection is stable: the timer keeps running while you are offline and answers entered offline are not saved.
- Take public assessments in your languages to pre-qualify, so the Talent team can contact you first when urgent projects open.
- If a real technical fault hits, take a screenshot and file a ticket naming the assessment.
Why people get rejected
- Breaking a rule (leaving or refreshing the window, keyboard shortcuts such as Ctrl+F, a second screen or using your phone): the assessment submits at once, and this does not earn an early retake.
- Running out of time: the assessment submits automatically and cannot be reopened.
- Scoring below the project's minimum, shown as 'Declined'; thresholds and wrong answers are not shared.
- A VPN or proxy during screening, which can decline an application automatically.
- Registration that fails Welo Data's verification and security checks: Trustpilot reviewers in 2026 say this ended in permanent deactivation with no reason given.
- Applying with several email addresses, which Welo Data says can hurt current or future applications.
After an automatically scored assessment your application status usually updates within 30 minutes; if a person reviews your answers it can take up to one week. Welo Data publishes no overall time from application to first paid task.
You invoice each purchase order in Workday, and Welo Data invoices are paid 14 days after Welo receives them (Welocalize's other entities pay after 45 or 60 days). Payments go out in batch runs that start on Wednesdays, into your Hyperwallet account, and the last settlement step usually takes 24 to 72 business hours. A few locations are paid only by wire transfer.
Tips to get accepted
- Purchase orders are issued weekly by default (each Sunday); you can switch to daily or monthly in Workday, and only one purchase order can be invoiced at a time.
- Withdraw from Hyperwallet regularly: funds left for six months are removed as abandoned. US payees pay no transfer fees; elsewhere fees depend on the method.
- Before registering or applying, disconnect VPNs, proxies and iCloud Private Relay, and do not apply from a library, university, internet cafe or workplace network: Welo Data has to confirm your location for sanctions, export-control and data-protection checks.
- Use one email address for every application: Welo Data says multiple addresses may hurt current or future applications.
- Keep your Welo Works profile up to date and check the job board, which is updated daily: the team reaches out when upcoming projects match your skills.
- Only trust email from @welocalize.com, @welodata.ai or, while you apply, @hire.lever.co, check that the job is on its official board, and expect an official agreement before any work starts.
- Do not read a project invitation as a pass: invitations go out automatically from your general profile, without checking your earlier assessment results.
What isn't public
- Welo Data shows you your own assessment scores but not the pass thresholds, maximum scores or which answers were wrong, and gives no reason when its security checks deactivate an account.
- No acceptance rate and no typical time from application to first paid task are published.
- The help center does not say whether assessments, learning modules and client exams are paid; Trustpilot reviewers say the tests were unpaid, while one first-hand reviewer's project paid for mandatory training.
- There is no rate card: pay is set per role, only 156 of the 302 Welo Data postings on its Lever board state an hourly rate (read 6 November 2026), and posted rates vary widely by country.
- The help center is shared with the parent, Welocalize, and not every article is current: the apply guide still sends assessments to Mettl, which the Assessment FAQ says is no longer used, and the worker platform is called both Welo Works and AI Trainers.
- How US-based raters who are hired as part-time W-2 employees are paid (payroll rather than invoices) is not spelled out for Welo Data specifically.
- Its AI Trainers site (announced 27 October 2026) and its help center still disagree (both read 6 November 2026). The site says you can re-apply 30 days after a fail, an assessment takes 45 to 90 minutes at your own pace, approval takes up to 3 to 5 business days and pay comes after each project with no batch cycles; the help center says retakes wait 6 months, tests are timed in one sitting, and invoices are paid 14 days after receipt in batch runs.

Is Welo Data a scam?
No. Welo Data is a real company.

Is Welo Data worth it?
Welo Data pays $4–$55/hr by country; voice session directors to $80/hr (platform-stated). It rewards credentialed experts who clear its assessment far more than open generalist work. Worker sentiment: Trustpilot (Welocalize page) 1.2/5 (103 reviews) · Trustpilot (Welodata page) 2.2/5 (8 reviews).
How does Welo Data pay out?
Tasks go on purchase orders, by default one a week, that you invoice in Workday; Welo Data invoices are paid 14 days after receipt, into Hyperwallet. US raters are part-time W-2 employees (Welocalize talent help center, Payment Terms).
Where can you work for Welo Data?
Global: each posting names the country or language it hires for, from India and the Philippines to the US, Germany and Japan, and 41 of its 302 postings are on site, 39 in California and 2 in Seattle (its Lever board, read 6 Nov 2026). Its site cites 155+ locales and 100+ languages.
How do I get accepted on Welo Data?
Apply to a specific role, register in Welo Works and complete that role's steps: screening questions, NDA and CV, timed assessments, an Okta account, learning modules and a client exam. Pass them all, confirm the job, and the project team contacts you.
Can I retake a Welo Data assessment?
Generally not. You qualify for a retake 6 months after you completed an assessment, including when it submitted automatically because a rule was broken, and certifications renew every 2 years.
Why was my Welo Data application declined?
'Declined' means your assessment scores did not meet that project's minimum. Each project sets its own thresholds, which Welo Data does not share, and it gives no answer-level feedback; the same score may still qualify you for a different project.
How does Welo Data pay?
Through Hyperwallet: you invoice each purchase order in Workday, and Welo Data pays its invoices 14 days after receiving them. A few locations are paid by wire transfer instead.
How do I know a Welo Data recruiter is real?
Its Trust & Safety page says it contacts people only from @welocalize.com, @weloglobal.com and @welodata.ai addresses (aitrainers.tech is also its own), never asks you to pay, buy equipment or give financial details outside your signed-in account, and always sends you to its own platform to apply, even when it first reaches out on LinkedIn or another social network.
