Apollum

Too many channels, none of them doing justice to the product. Apollum consolidates the secondary market into a brand-centred, international platform.

The demand is there. The infrastructure is not.

400 sources

HiFi Shark aggregates active secondhand listings from over 400 platforms — illustrating just how fragmented the market is today.

1.8 m

Monthly visits to HiFi Shark alone. Buyers are actively searching — on platforms that do not do justice to your inventory.

25 %

Annual growth of specialised resale platforms according to McKinsey — significantly faster than the overall market.

8–11 %

Annual growth of the global secondhand luxury goods market — high-end audio has yet to benefit.

Pre-owned listings are spread across dozens of platforms with no certification, no brand presence and no curatorial framework.

Other industries are further ahead: 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.

This is how other luxury segments have long since professionalised the certified pre-owned approach — high-end audio has not.

No brand experience

Generic marketplaces such as eBay or classified ad platforms offer no specialisation, no quality control and no brand experience — your inventory disappears into the noise.

Enormous maintenance effort

Anyone operating professionally today juggles eBay, Audiogon, classified ads and their own website simultaneously — with duplicated work, inconsistencies and fragmented reach.

No differentiation

Authorised dealers are structurally indistinguishable from anonymous private sellers on generic marketplaces. Authorised status remains invisible.

High-quality dealer profile

Inventory, brand connections, service offerings and reviews in one place — visible to an audience that knows exactly what it is looking for.

Brand authorisation as a structural advantage

Dealers of participating brands are identified as brand-authorised. Buyers can see at a glance who inspects according to a defined standard.

Trade-ins as a revenue stream

When a customer upgrades, the old unit finds a buyer directly through Apollum. What was a stock problem becomes a structured resale channel.

Network synergies

A dealer who sells an amplifier refers the buyer to a service partner. Connections that today rely on personal networks become structural.

Certifications as a source of remuneration.

Authorised dealers carry out inspections for certified listings and receive a proportional fee for each certificate issued — a revenue layer that did not previously exist.

No commission model

Apollum is based on a flat monthly fee. The sale price achieved remains entirely with the dealer — no transaction fees, no hidden costs.

Authorised dealers pay no platform fee

The participating brand covers these costs for its network. For authorised dealers, this creates a fully operational channel with no investment of their own.

API integration with existing shop systems

Listings are transferred once. Stock levels, prices and availability remain automatically synchronised — without manual maintenance on yet another channel.

Every transaction creates the next.

Apollum connects dealers, brands and service partners on one platform — with mutual value creation. Connections that today rely on personal networks become structural.

Trade-ins as a revenue stream

When a customer upgrades, the old unit finds a buyer directly through Apollum. A structured resale channel turns trade-ins from a stock problem into a revenue stream.

Network synergies

A dealer who sells an amplifier refers the buyer to a service partner. A service partner lists refurbished units through a dealer. Apollum makes these connections structural — rather than leaving them to the chance of personal networks.

Certifications as a source of remuneration

Authorised dealers can carry out inspections and refurbishments for certified listings. For each certificate issued, they receive a proportional fee — a new revenue layer that did not previously exist.
