Buyer’s speedy guide: the way to choose the appropriate partner.

  1. Establish annotation complexity – different skills are required with regard to bounding boxes, semantic segmentation, and 3D LiDAR.
  2. Security & compliance — request SOC2/ISO/ GDPR compliance in case you will transfer sensitive or PII data.
  3. Pilot first – run a small curation + inter-annotator agreement (IAA) test to estimate quality.
  4. Tooling & APIs — verify export formats, connect with your pipeline, pre-labeling support and QA processes.
  5. Scale & SLAs- make sure that the vendor is able to scale annotators, languages as well as coverage of shifts to satisfy deadlines.
