Who we are
Integrity no matter what
We are mindful of the impact of our actions.
We act with integrity and hold ourselves and others to accountable.
Inclusive and sustainable
Sigma is dedicated to building teams, tech, and business practices that are good for people and good for the planet. We believe that when people of diverse backgrounds and identities feel included and impactful in a team, they get the best, and most sustainable, results.
Humans are at the heart of AI, and at the heart of everything we do. From our inclusive teams to the way we design processes, to the customers we serve, we act with the purpose of making human lives better.
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.
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.
Spotlight on annotation
How does AI 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.
