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.
