What we do
How does an artificial intelligence learn to listen and speak? The same as a child does. You need to teach it the right words and concepts to understand the world around it. At Sigma, we collect, prepare and label the data that companies use to train AI programs to understand speech, text, images, videos and more.
Our annotators are at the heart of this process. With their diverse backgrounds, experience, language skills and perspectives, they interpret and label AI training data with a human touch, helping AI serve humanity better and with less bias.
Who we are
Humancentric
Humans are at the heart of everything we do. From our inclusive annotator teams to the way we design processes to the customers we choose to serve, we do so with the purpose of making human lives better.
Challenge lovers
We’re at our best when we tackle complex challenges. Instead of sticking to standard solutions, we strive to find the best approach to solve a problem — and we’re keen to grow and learn new things to get there.
Empathetic collaborators
Discussion culture and empathy go hand in hand at Sigma. When we put our egos aside and put ourselves in our teammates’ shoes, it allows us to talk through even the toughest situations together.
Expert advisors
From our founder’s decades-long experience in AI research to our annotators with deep knowledge of over 250 languages and dialects, everyone at Sigma is an expert in their area and has something important to contribute.
