hello world!
Justt has compiled a list of 21 fraud prevention influencers who might be worth your while to check out

Knowledge sharing and cooperation are key to the success of modern-day fraud fighters, just like it is to the online-based criminals they face. While fraud fighters can probably learn something from talking to any of their colleagues across the globe, there are “influencers” in the space who excel in exchanging information and/or generating useful, detail-driven conversations on topics of interest. To assist others in the fraud fighting community out there, Justt has compiled a list of 21 fraud prevention influencers who might be worth your while to check out along with links to the relevant channels and fora where they are present.



The list is not ranked or ordered according to any specific logic. We tried to gather a diverse group of people in terms of the types of fraud covered and geographic location of the people listed. However, this list is by no means exhaustive and may exclude some names you think should be on it. If you have anyone to suggest adding to the list, feel free to contact us and let us know.

And should you and your company be dealing with a chargeback problem, sign up for a demo and learn what we can do to help you.

With those disclaimers out of the way, let’s get to the list!
