AI data solutions for teams building models
YO AI Labs is an AI data solutions company specialising in high-quality data annotation, data labeling, AI training and human-in-the-loop services that power the next generation of artificial intelligence.
We partner with AI companies, enterprises and research organisations to build reliable datasets for large language models, generative AI, computer vision, NLP, speech AI and reinforcement learning from human feedback.
What we deliver
How we work
Our global network of skilled domain experts, linguists, engineers and data specialists delivers accurate, scalable and secure AI training data across multiple industries and languages. Every engagement is built around three things:
| What it means in practice | |
|---|---|
| The right expertise | Contributors are matched to your domain — a licensed clinician for clinical reasoning, a qualified lawyer for jurisdiction-specific legal work, a practising engineer for design review. |
| Quality that is measured | Work is graded against your rubric with inter-annotator agreement tracked, not asserted. Rejected work is reworked rather than shipped. |
| Scale without drift | Capacity ramps by adding qualified reviewers to an established rubric, so throughput rises without quality falling. |
Domains we cover
Our current contributor pool spans 30 professional categories, including software engineering, data science, medicine, law, finance and accounting, mechanical, electrical and civil engineering, design, writing, education, and language and localisation.

Modalities
- Text — LLM evaluation, preference data, reference answers, classification, extraction.
- Code — repository-level reasoning, generated code review, agent trajectories.
- Image and video — segmentation, detection, keypoints, temporal and event labelling.
- Audio and speech — transcription, diarisation, accent and quality evaluation.
- Multimodal — tasks spanning several of the above in a single rubric.
Our mission
We are committed to helping organisations accelerate AI innovation by delivering high-quality datasets, expert human intelligence and scalable AI operations. Our mission is to bridge the gap between human expertise and artificial intelligence, so businesses can build smarter, safer and more accurate AI systems.
Building better AI through better data.
