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.

“Signifyd is a great place to be a data scientist. I've really appreciated the supportive team, and spirit of collective endeavour and exploration. There's a great culture of open discussion and evaluation of new methods, proposals and competing priorities. Away from data science, the Belfast office has the best benefits of any company I've worked for, including lunches, lots of snacks and monthly socials.”
