We’re building the new identity standard for the internet.

Whether you want to open a bank account or hire a car, our lives are moving online. That means millions of everyday interactions now happen digitally—without ever meeting anyone face-to-face. Increasingly, our identities are becoming the new currency which we use to access online services. But with half the world being unbanked, and identity fraud on the rise, that’s becoming more and more difficult. So our mission is to create an open world, where identity is the key to access.

We use machine learning to assess whether a user’s government-issued ID is genuine or fraudulent, and then compare it against their facial biometrics. As a global leader in computer vision, our AI learns to identity fraud as it evolves over time. Our goal is to apply cutting-edge research to build powerful, simple products that drive inclusion and safety online—without compromising on user privacy.

That’s how we give companies like Revolut, Zipcar and Bitstamp the assurance they need to onboard users remotely and securely across 195 countries… and we’re just getting started!

Founded in 2012, we're a diverse, global team of 250 technologists spread across 6 countries. We've also received over $60m in funding from world-class technology investors including Salesforce and Microsoft.
