Is Meridial (Invisible Technologies) legit?
A real marketplace run by Invisible Technologies, which posts hundreds of contract listings on its own job board. Trustpilot reviews for both meridial.ai and invisibletech.ai are mostly negative. They describe unpaid assessments and onboarding that led to no work, stalled ID or address checks, slow support and accounts deactivated without explanation. A third-party review of Reddit threads found contributors who say they are paid every two weeks, alongside reports of accounts put under review just before payday.
Does it pay? mixed
What you do
Domain experts (law, STEM, finance, coding, languages and more) write prompts and reasoning, evaluate and rank AI outputs, design rubrics and tests, and red-team models on per-project contracts. Each engagement is scoped in a Statement of Work that shows its rate and expected length.
The details
- Pay
- $6–65/hr
As published: Its job posts on its own Greenhouse board say 'a pay range of $6 to $65 per hour', with the exact rate set by experience, expertise and geographic location. The students page lists $15 to $20/hour for search-results evaluation. Meridial says it shows a rate for every engagement before you start, pays for all time on projects and takes no platform cut. - Open in
- Project availability depends on client needs, expertise and geographic eligibility.
Varies by project. Listings include 'World Wide - Remote' roles as well as single-country roles (e.g. US, Chile, Bangladesh). The site cites a network across 120+ countries but publishes no country list. - You need
- computer (laptop or desktop, modern browser, 8GB RAM), internet of at least 10 Mbps, camera (identity confirmation only)
- Paid by
- Every two weeks, to the account details in your profile
- Company
- Meridial: expert-contractor marketplace 'powered by Invisible Technologies' (Invisible Technologies Inc.). invisible.co redirects to invisibletech.ai, whose careers page links 'Expert opportunities' to meridial.ai.
- Backers
- Invisible Technologies raised $100M in September 2025 at a valuation above $2B (per Bloomberg), led by Vanara Capital with Acrew Capital and Greycroft (SiliconANGLE).
Red flags
- Pay range starts at $6/hour and the company says the rate depends partly on your geographic location
- Trustpilot reviewers (meridial.ai 1.5/5 from 35 reviews; invisibletech.ai 2.3/5 from 10) report unpaid assessments and deactivations without explanation
- Reports collected from r/Meridial (via Annotation Academy) of accounts placed under review just before payday, with work done before that left unpaid
- Trustpilot reviewers object to proctored assessments that require camera, microphone and screen access
What we couldn’t confirm
Payout method is not named on Meridial's pages (Annotation Academy reports Wise from Reddit threads; not confirmed). No minimum age or country list is published. Meridial's /projects page showed '0 projects' when fetched while its Greenhouse board listed 827 jobs, so the live project count could not be settled. Reddit could not be opened directly; Reddit evidence comes only through Annotation Academy's summary.
We are not affiliated with Meridial (Invisible Technologies). Pay and availability change; confirm on the official site before you start. Never pay to get work.
