DEMOCRATIZING FRAUD PROTECTION

On a mission to protect every online business from fraud.

We believe in the power of APIs and modern business practices, like transparency and simplicity.

In my home country of Sweden, digital identity has long been part of everyday life. My vision is to bring the same level of protection to everyone on the planet.
