      Data Annotation Review from Nazar Mysholivskyi

      We worked with Tinkogroup on a manual data annotation project supporting our content moderation and AI training workflows. The scope was fairly complex, around 250,000 images and video frames labeled across multiple attributes, including some subjective categories like brand suitability and contextual safety. What stood out was how thoughtfully their team approached the work. Communication was straightforward and reliable. We had a single point of contact, regular check-ins, and good visibility into progress. They were also flexible when we updated guidelines or increased volume. After the initial ramp-up, delivery timelines became predictable, which helped us stay aligned with our training schedule. Tinkogroup is a dependable partner that delivers solid quality and added value beyond execution.

      Back Office Outsourcing Review from Vitaliy Kryvoruchko

      We partnered with Tinkogroup to improve the quality of our internal datasets used for client reporting and analytics. They processed data from multiple sources, removed duplicates, fixed formatting issues, and validated key fields to ensure consistency. The final datasets were delivered fully structured, documented, and ready for immediate use.
