We know what an online business needs.
Because we've been there.

We know exactly what life is like as an online business. That’s because, before we launched Ravelin, we ran an online business ourselves.

We wrestled with the delicate balance between blocking bad guys and admitting honest customers; fighting to protect our margins while preventing fraud. Ravelin was launched in 2015 and continues to encapsulate all the insight, experience and expertise that our growing team can bring. 

But that experience as merchants continues to underpin our culture. It informs every decision we make and it’s the reason that Ravelin works better than other systems in the real world. Which should come as no surprise because, when it comes to the fight against fraud, we’ve been there.
