Presentations
Overview:
As digital businesses accelerate, fraud risks are evolving just as quickly. Many teams only realize how exposed they are once growth outpaces their defenses, when chargebacks rise and manual reviews begin to strain operations.
Harper, an innovative and rapidly growing retail technology company providing try-before-you-buy services for online fashion shopping, took a proactive approach instead of waiting for that moment.
Danièle Thillmann, Head of Fraud & Payments, will share how Harper built future-ready fraud operations to stay ahead of risk. By moving from fragmented systems to a unified, data-driven platform built with SEON, Harper created a scalable framework that delivers both protection and a frictionless customer experience.
Attendees will learn what it takes to build fraud prevention that scales with the business, and why anticipation, not reaction, is becoming the next competitive advantage.
Why It Matters:
Every fast-growing merchant faces the same challenge: scaling quickly while maintaining security and a positive customer experience. Without a forward-looking strategy, the gap between growth and risk only widens.
This session offers a pragmatic roadmap to break that cycle, showing how Harper’s early investment in modern fraud infrastructure created resilience, agility, and confidence across the organization.
It is a story of anticipation over reaction, and a blueprint for merchants that want to grow without compromise or friction.
