Case Study: Buycycle reduces false positives and scales globally with SEON

How SEON Helped Buycycle Cut False Positives and Go Global

Buycycle is a fast-growing global C2C marketplace for high-value bicycle transactions, operating across 33 countries and handling tens of thousands of sales. As it scaled, the company faced fraud risks across multiple points in the user journey, including bot sign-ups, off-platform messaging attempts, hidden contact details in listings, and payment fraud, while also needing to keep false positives low and avoid adding manual review overhead. SEON was brought in as a fraud prevention partner to provide device intelligence and a holistic risk view.

SEON implemented a streamlined, automated fraud framework that tracked risk from sign-up through checkout, using its device fingerprinting and rules engine to identify bad actors earlier and fine-tune decisioning. Working closely with a dedicated fraud specialist, Buycycle shifted fraud detection to the earliest touchpoint, reduced false positives in under three months, and cut off-platform messaging and fraudulent transactions by stopping threats at sign-up. The result was more efficient operations, no need for manual review, and the ability to scale securely across 33 countries without increasing fraud team headcount.
