Dataset-as-a-Service
Your Proprietary Dataset, Managed
Our Dataset as a Service for computer vision is a subscription, not a project: we design, collect, annotate, version, and continuously refresh your proprietary dataset, growing it with new edge cases each cycle. so your models always train on current, documented, exclusively-yours ground truth.
Most annotation engagements end at delivery; datasets then rot as products, environments, and edge cases change. Dataset-as-a-Service is a managed subscription: Obraz owns the operational loop — quarterly collection of new scenarios, curation against your model’s current failure modes, annotation, versioned releases with changelogs and coverage reports — while you own the data outright. Unlike off-the-shelf dataset stores, nothing is resold or shared; exclusivity and custody are contractual.
This is the recurring-revenue framing of what Appen calls custom data sourcing and creation, combined with versioned dataset engineering. Position it as the top-tier engagement model above per-project annotation. Guardrail: Do not add an off-the-shelf dataset catalog to this page — it contradicts the exclusivity pitch and the security narrative.
