Great job!

We had a great experience working with Tinkogroup on a recent data labeling project. Their expertise in data labeling helped us to fix issues with our dataset and classify thousands of new email replies, resulting in a significant improvement in the accuracy of our text classification model. Throughout the project, team was communicative, responsive, and flexible, and their commitment to quality was impressive. Overall, we highly recommend their services to anyone in need of data labeling or related tasks, and we look forward to continuing our partnership with them in the future.

Consistent, dependable, high quality work.

I have been working with Olga for nearly two years. She is consistent, dependable and does great work. Olga is very good at understanding my requests and what needs to be done to accomplish each task, but she is also good at clarifying anything that I haven't communicated clearly enough, rather than forging ahead in the wrong direction. Working with Olga enables me to save time without sacrificing quality.
