Apollum makes international communication effortless. The platform is available in more than seven languages — from the interface to the content. Messages between buyers and sellers are translated in real time whenever needed.

Trust becomes the standard. Apollum enables brands to establish their own certifications for pre-owned equipment directly on the platform — either by the brand itself or in collaboration with authorised dealers and service companies.

This creates new standards for verified quality and additional revenue potential in the secondary market.

All stakeholders. One platform. Brands, dealers, service providers and buyers are structurally connected on Apollum. The brand certifies, the dealer sells, the service partner maintains — and the buyer finds all three in one place for the very first time.

Modern infrastructure. Apollum is hosted in Germany in compliance with GDPR. For private translations, we use our own locally operated AI infrastructure.

Measurable results. What happens on the platform becomes transparent: prices, demand, buyer behaviour — for the first time as a reliable basis for decisions in the secondary market.

Founding Circle. Brands, dealers and service companies that join Apollum from the very beginning benefit from exclusive conditions. Please do not hesitate to contact us.
