The outcome
What clients actually get.
70%reduction in labeling labor cost
99%+delivered data accuracy
100%of frames pass second-stage QA
Yoursdata and related IP belong to you
Quality pipeline
A three-stage annotation and QA pipeline.
Every frame passes through production, review, and management before it reaches you.
Annotation
Trained annotators label to the client ontology and guidelines, with daily and weekly reporting. Annotators hold a BSc.
Annotation plus QA review
A QA analyst performs second-stage annotation and reviews 100% of frames in real time, against a minimum 98.5% accuracy threshold.
QA management
A QA manager unblocks impediments, tracks quality and turnaround KPIs, manages risk and escalations, and drives continuous improvement.
