Forter sells AI-powered software that helps online businesses spot and block fraudulent payments and fake accounts before a purchase goes through.
Forter is a fraud-detection company for the internet. When you check out on a website and your card is approved in a blink, there is a decent chance a system like Forter's just decided in that blink that you are a real person and not a crook. Online merchants pay Forter to make that call for them, on every order, in real time.
The problem it solves is simple to state and hard to do. A store loses money two ways: it can let a stolen card through and eat the chargeback, or it can reject a legitimate customer and lose the sale forever. Forter sits in the middle and answers one question — should this transaction be trusted? — using patterns it has learned from a huge network of merchants and shoppers, plus data about the device, the identity and the behavior behind each purchase. An order that looks fishy gets stopped before it completes. That same identity engine has grown into a bigger business. Beyond payments, Forter sells tools that catch fake account sign-ups, stop fraud rings, and help merchants approve more good orders instead of waving them away. Its customers are mostly large digital businesses — retailers, marketplaces, travel sites and payment providers — who handle enormous transaction volume and cannot afford either kind of mistake at scale.
The company was founded in 2013 and is based in New York. The clever part of the model is the network effect: every merchant that joins makes the shared picture of "normal" versus "suspicious" sharper for everyone else, which is hard for a lone in-house fraud team to match. The name to know is Forter — it once went by Ryzyco, but today it is firmly Forter, selling trust at the speed of a click.
