Our mission is to make commerce safer for online retailers.


Since their days at PayPal and FedEx more than a decade ago, Signifyd’s founders knew something wasn’t right about the way online retailers were on the hook for fraud.

Fraud protection at the time was a world of cryptic scores that humans puzzled over before deciding whether an order should be shipped or cancelled as fraudulent. A wrong answer meant either losing out to fraudsters or withholding orders from legitimate customers.

There had to be a better way — a way that relied on big data, machine learning and domain expertise to offer a yes-or-no decision on an order in milliseconds.

And so, Signifyd was born.

We backed the idea and the technology with a 100 percent financial guarantee on any approved order that later turned out to be fraudulent. Signifyd's Commerce Protection Platform now protects the largest network of merchants globally.
