Reading Time: 2 Minutes

Welcome to the inaugural Blog for Sigma AI! We have recently undergone many changes here at Sigma in order to provide an even more personalized and better service, emphasize our industry leading results, and highlight our extensive capabilities and experience in data creation, cleansing, labeling, and annotation.

Sigma AI is dedicated to getting you the highest quality, most accurate training data, the way you want it, when you need it, at the right cost. 

We feel we are a very unique company in the data annotation space due to the considerable experience of its senior team in Artificial Intelligence. In the early 90’s, Sigma AI’s senior team designed and developed the first of its kind user-friendly tools for massive and collaborative data annotation, reducing the annotation time by 85% while keeping accuracies over 98%. Since then, the Sigma AI team has continued to improve the tools and methodologies and have worked in successfully automating certain parts of the annotation process. 

This extensive experience allows us to have the AI knowledge and expertise necessary to understand all the data project nuances and to make communication with our client’s Data Operation Managers, Engineers, Data Scientists and Linguists smooth and productive.

Also, Sigma works with 120+ languages and complies with the highest privacy and security standards (100% GDPR and CCPA compliant. ISO27001 certified). 

With the inauguration of our Blog, we start a new phase in which we will share the lessons learnt in over 30 years working on data collection and annotation. We will share information about important topics such as security and privacy, data quality, the use of Machine Learning in data annotation, examples for audio, text, images and video annotation, free training data, annotation tools, statistics from real use cases, and reports and analysis about training data and AI.

There is a great professional and motivated team behind this initiative. I really hope that all our blog articles are of help and welcome your feedback and preferences.

It is also my hope that you enjoy the content we have to share over the coming months. And that you think of us when you are at a stage of technology or product development when the  sheer amounts of training data you need require to scale fast while keeping a high quality, or when you need help to broach a challenging data project. We guarantee we will outperform your current solution.
