Apollum
Sometimes great listening starts elsewhere. Discover our most popular listings.
Pre-owned components change hands every day — on generic marketplaces, in forums, on dozens of niche platforms. Without quality standards, without brand presence, without any curatorial framework.

Of Generation Z prefers pre-owned by conviction — the buyers of tomorrow are entering through the secondary market.
Rolex has its own CPO programme with a 2-year warranty. Gucci works with Vestiaire Collective. In the automotive sector, programmes such as Mercedes "Junge Sterne" or Porsche Approved are standard practice.
Other luxury segments have long since professionalised the certified pre-owned approach — high-end audio has not. Pre-owned listings are spread across dozens of platforms with no certification, no brand presence and no curatorial framework.
Whoever issues the certificate controls the trust standard in the market — and monetises that trust directly. Brands that ignore their secondary market cede it to third parties and lose control over price, quality and brand experience.
No brand presence
Representation, condition and positioning in the secondary market lie entirely outside the brand's sphere of influence — the brand experience ends with the first purchase.
No value stability
Without certification and standards, prices fluctuate arbitrarily. This damages perceived brand value — including in the primary market.
No data
Which products are being traded? At what price? By whom? Today, brands have no visibility into the secondary market of their own products.
A dedicated brand presence with products, dealer network and curatorial framework — a presence in resale that does justice to the brand in terms of quality and context.
Brands define what "Certified by …" means: with clear inspection criteria, condition categories and authorised parties — to protect the quality promise and as a new revenue stream in the secondary market.
Brands can offer paid certifications — "Certified by Brand", "Brand Verified". This creates a new source of income in the secondary market that did not previously exist, and re-engages the customer with the brand.
A lower entry price in the secondary market lowers the barrier for first-time buyers — analogous to the pre-owned car as a brand entry point. Today's pre-owned buyers become tomorrow's new customers.
Apollum makes the brand's authorised dealer network visible and navigable in the secondary market for the first time. Buyers can see at a glance who is brand-authorised — the distribution structure extends into resale.
Which models are being traded at what price? Who is buying? Apollum provides structured data about a brand's own secondary market for the first time — a foundation for informed product decisions.
Visibility in front of a highly relevant, purchase-ready audience — people who are actively engaged with high-end audio and make brand decisions consciously.
Structured data creates transparency over a brand's own secondary market for the first time. Lower entry prices open up new buyer groups — today's pre-owned buyers become tomorrow's first-time buyers.
Apollum is based on subscription models without transaction fees. Beyond that, the platform opens up a second revenue layer: paid certifications.
Subscription model
Brands pay a monthly fee and an amount per authorised dealer — their dealers pay nothing. The brand absorbs these costs to eliminate friction and accelerate adoption across the network.
Certifications as a second revenue layer
Brands issue official certificates, dealers earn from inspection and refurbishment, Apollum receives a platform fee.
Founding Circle
For brands who wish to be involved early, we offer exclusive conditions — with the opportunity to help shape the platform from the outset. Launch is planned for late 2026.
