Our senior team has over 30 years experience in Training Data Annotation. It was in the early 90’s when they developed the first specific user-friendly tools for massive and collaborative data annotation in the world, reducing the annotation time by 85% while keeping accuracies over 98%.

Since the creation of Sigma in 2008, the team has continued to work in improving the data annotation processes and tools to achieve even higher efficiency, data quality and security. In particular, the development of Machine Learning (ML) and Digital Signal Processing (DSP) assisted tools together with the unique approach to tools development has helped significantly improve all the Key Performance Indicators (KPIs).

In Sigma we recognize that each client is unique and has its own specific objectives, strategies and procedures. We also recognize that each data collection or data annotation project has its own particularities that need to be analyzed and taken into account.

It is for these reasons that Sigma’s approach is very flexible. Whether we use the client tools and procedures or we use our own, whether we provide the services remotely, on premise or in our highly secure facilities, we’ll go to the end of earth to provide the best service possible. This includes the adaptation of our human and technology resources as well as our work procedures to the client and the project
