Mission
Better Data for Every AI TeamHelp companies of every size build smarter, safer, and more capable AI by giving them accurate, consistent training data they can trust, delivered on time and at scale.
About Smart Annotahub
We are a specialist data annotation company helping AI teams build frontier models on better data, with dedicated annotators, engineered quality, and project leads who understand the work.
Our Story
Built by Annotators, for AI Teams
Smart Annotahub started in Ha Noi, Vietnam, with a team of annotators and operations leads who had seen the same problems again and again: inconsistent labels, unclear QA, and vendors who stopped listening once the contract was signed.
We set out to build the partner we would have wanted ourselves. Every project gets a dedicated team, written guidelines that evolve with your data, and a lead who has done the labeling work first-hand.
Today we support AI teams across computer vision, NLP, audio, and 3D perception, from no-cost pilots to production-scale delivery.
Philosophy
Growth Built on TrustSustainable growth starts with trust: between us and our clients, within our teams, and in the quality of every label. We prioritize transparency, responsibility, and long-term partnership over quick wins, so our work holds up today and tomorrow.
