Our marketplace is growing rapidly and so is the number of users that attempt to use it for fraudulent activities.<p>I am looking for a solution that could give us early warnings about users based on information that they input, e.g. "This email address was first seen in last 24hrs".<p>We have Stripe Radar, but that only kicks in when they attempt to make a payment, which is slightly too late.<p>At the moment, I am using Clearbit for this – I simply check if there is any information about the user in Clearbit, and that is proving to be a powerful signal. However, I am looking for a purpose built platform to pull warnings about users based on the information that we have.
A fair number of risk-assessment vendors do that. Usually they consider more data than just email address. Riskified, Sift, and Signifyd are 3 of the better-known ones.
