Client Testimonials

How clients talk about their experience with Kotwel

Steven A

Steven A.

Tech Company

Back when our company was scaling up, we needed to outsource our data processing. It was our first time seeking partners, so we proceeded cautiously. We reached out to over 10 companies, shortlisted 4, and had them compete by completing a full-scope data task on our application. Despite Kotwel having a slightly higher price, we still chose them for their superior quality, transparent communication, and professionalism. No regrets there! We've been extremely satisfied with Kotwel, not only on our first project but also on all the follow-ups. Can't recommend them enough – they've been a game-changer for us!

We’ve worked with Kotwel on three projects so far, and we are amazed by the precision and consistent quality they deliver. Their expertise and attention to detail in annotating diverse datasets have significantly enhanced the performance of our machine learning models. Another plus point is that the smooth collaboration with our internal team has made the annotation process efficient, stress-free, and enjoyable.

I personally commend Kotwel for their dedication to both quality and social responsibility. Knowing that our research projects held a not-for-profit purpose, they offered us a not-for-profit price and went the extra mile to support us in any way they could.

We hesitated initially to contact Kotwel because of our previous negative experiences with other data providers, especially regarding quality and communication. However, Kotwel quickly proved themselves. As we dived into projects with Kotwel, our doubts turned into confidence. The consistently high-quality deliverables and their proactive communication style fostered a trusting relationship. It was a refreshing change that solidified our decision to choose Kotwel as our partner.
