Apollum
Sometimes great listening starts elsewhere. Discover our most popular listings.
We organise the secondary market for high-end audio — curated, brand-centred, global.
Founded in Münster,
hosted in Germany,
at home in the world.
The products at the heart of this are built to last. A fine amplifier, an exceptional loudspeaker — they do not age, they are passed on. And yet: when such equipment changes hands, it does so on platforms unworthy of it. Among household appliances and second-hand cars, without context, without classification, without the respect these objects deserve.
That is the starting point of Apollum. Not a market trend or a growth forecast — but the simple conviction that exceptional things deserve an exceptional setting. Even in their second life.

Apollum derives from Apollo — the Greek god of music, poetry and the arts. A figure associated less with raw power than with harmony, proportion and the pursuit of beauty in sound.
The name also carries a phonetic echo of "Volume" — a quiet allusion to what Apollum is fundamentally about: making exceptional audio experiences visible, amplifying them and placing them in the right context.
Who we are. What we are building. What we stand for. Further insights into the company, the platform and our approach as a considered alternative to conventional marketplaces.
Apollum is a subsidiary of uneo GmbH and was founded on 18 December 2025 as apollum highend GmbH — headquartered in Münster, Germany.
Behind the project are people who believe that the high-end audio secondary market deserves a better infrastructure.
Apollum will be the first brand-centred industry platform for secondhand high-end audio. No classified ads. No generic marketplace.
A curated, high-quality environment where brands, dealers and buyers come together — with the standard and structure this industry has long been missing.
The close international interconnection of brands, dealers, service providers and end customers creates the foundation for greater trust, transparency and long-term value stability.
In other luxury segments, this has long since evolved into a professional certified pre-owned approach. In high-end audio, this structure has been absent — until now.
Apollum closes this gap — with certification infrastructure, transparent dealer networks, structured product data and a platform available in more than seven languages.
Apollum is not a marketplace for everything and everyone. We are not building a platform that convinces through sheer volume.
What interests us is depth: the breadth of offering of a global network, the depth of content in product presentation and the structural depth of an infrastructure that genuinely connects brands, dealers and buyers.
