Today, Global App Testing launches "AI GroundTruth ": The First Human-Centered GenAI Evaluation Service for AI Leaders Deploying at Scale.
As GenAI products race to global markets, GAT AI GroundTruth gives AI leaders the only thing synthetic benchmarks can't: real human judgment in real-world contexts
Barcelona, MWC, March 3rd 2026 – GenAI is scaling fast. But most AI products are evaluated by other AI; synthetic benchmarks, automated scoring, and LLM-as-a-judge tools that can't catch cultural missteps, trust failures, or the edge cases that only real humans in real contexts will find. Companies are shipping blind. And the risks are real: reputational damage, regulatory exposure, and user trust that once lost is nearly impossible to rebuild.
Today, at Mobile World Congress Barcelona, Global App Testing (GAT) launches GAT AI GroundTruth , a new service that deploys real humans across 190+ countries to evaluate GenAI outputs for trust, safety, and Responsible AI compliance; before products reach market.
MWC is where the world's most ambitious technology leaders gather to shape the next wave of global connectivity and AI deployment. It is the right place to make this announcement. Because the challenge GAT AI GroundTruth solves is exactly the one keeping AI leaders up at night as they prepare to deploy at global scale.
"Think less testing, more evaluation," said Nick Viney, CEO of Global App Testing. "GenAI applications are in ferocious competition, and the winners won't just be the ones who scale fastest. They'll be the ones who understand how their product actually behaves with real users in real markets; and how it holds up against the Responsible AI standards that regulators and users increasingly expect."
Powered by GAT's crowd of 120,000+ professional evaluators across 190+ countries, GAT "AI GroundTruth" gives AI leaders three things no automated tool can provide:
Risk mitigation: Catch trust failures, safety risks, and Responsible AI gaps before they reach customers; not after
GenAI is fundamentally different from traditional software. Every response is unique, context-dependent, and shaped by the user asking the question. You can't test your way to confidence. You need human judgment.
"The question keeping our team up at night isn't whether our model passes benchmarks. It's whether users in markets we care about will actually trust it. That's a human judgment call and no automated tool can make it for us," said one leader whose remit included Responsible AI, a Global AI Platform.
"What we consistently find is that AI products optimized for English-speaking Western users fail in ways their builders never anticipated when deployed in other markets," said James Atkin, Global Lead for GenAI Evaluation at Global App Testing. "The failures aren't random; they're systematic. And they're only visible when real people in those markets actually interact with the product. That's the gap GAT AI GroundTruth was built to close."
"We've been red-teaming our own models internally for months. What we can't do internally is replicate the diversity of real users across different cultures and contexts at scale. That's exactly what this service provides," said a Senior AI Ethics Leader at a Top-10 Technology Company.
A leading conversational AI platform used GAT AI GroundTruth to identify 18 cultural misalignments and 3 critical trust-breaking moments before launching in Southeast Asia; avoiding potential PR backlash, reducing Responsible AI exposure, and accelerating time-to-market by 6 weeks.
GAT clients have historically achieved 250% market share increases through real-world product optimization. The company is now bringing that same rigor to GenAI evaluation.
The next phase of AI growth won't come from scale alone. Regulators are tightening. Users are more discerning. And Responsible AI is no longer a nice-to-have; it's a commercial imperative. The companies that will win are the ones who know how their product behaves with real users, in real markets, before it ships.
GAT AI GroundTruth is the only service that combines the scale of a 120,000+ global crowd with the rigor of structured human evaluation; giving AI leaders the confidence to deploy responsibly in any market, for any user, without guessing.
The GAT team is on the ground at MWC Barcelona this week, available for conversations, briefings, and exploratory consultations at the British Pavilion. To arrange a meeting on site contact: info@globalapptesting.com or find Nick Viney, Andy Nolan, and James Atkin directly on LinkedIn.
