What Ad.Audio does

Ad.Audio GmbH is a Hamburg- and Garching bei München-based digital audio advertising marketer founded in 2021 that exclusively commercializes national DAB+ digital radio inventory in Germany, including the Absolut Radio station family, AIDAradio, and (since January 2023) Klassik Radio, alongside online audio streaming inventory. The company operates a Programmatic Radio platform that connects demand-side platforms — Virtual Minds' Active Agent, Hawk, and The Trade Desk — through the Ströer SSP to national DAB+ inventory, enabling automated real-time bidding and near-real-time campaign optimization on broadcast radio, a capability positioned as first-to-market in the German market.

Underlying technology combines DAB+ broadcast distribution with a programmatic SSP/DSP integration layer, complemented by contextual targeting (weather, sports, traffic, Google Trends) and a DAB+ Display Ad format that renders visual ads with integrated QR codes directly on DAB+ receiver devices. The Ströer SSP serves as the programmatic backbone, while first-party DAB+ audience research is co-produced with pilot Agenturgruppe.

Revenue is generated from classical spot sales (CPM-style unit pricing on 10,000-Kontakte blocks), programmatic guaranteed and non-guaranteed deals, online audio streaming, and Sonderwerbeformen (custom branded-content formats). A 15% AE-Provision is granted to agencies booking on behalf of clients. Customers include brand advertisers such as Vodafone, AIDA Cruises, freenet AG, IKEA, BMW, Shell, Lidl, Microsoft, and ATU, and media agencies including Ströer Media Solutions, Mediaplus Group, pilot Agenturgruppe, and basismedia, with the company operating exclusively in the German market and in close operational cooperation with Antenne Deutschland.

Direct peers

• AdsWizz (SiriusXM): AdsWizz is a global programmatic audio advertising technology platform acquired by SiriusXM, providing ad serving, programmatic buying and audience measurement for digital audio publishers. Directly comparable as a programmatic audio ad-tech stack; ad.audio is regional (Germany DAB+) while AdsWizz is global.
• Triton Digital (SiriusXM): Triton Digital provides programmatic audio advertising technology, marketplace, and measurement for digital audio and podcast publishers worldwide, now under SiriusXM. Directly comparable to ad.audio's programmatic radio offering — both monetize digital audio inventory through programmatic channels — though Triton is global podcast/streaming-focused while ad.audio focuses on broadcast DAB+.
• RMS Radio Marketing Service GmbH & Co. KG: RMS is the joint marketing arm of major German private radio broadcasters (e.g., RTL 104.6, Radio Hamburg). It sells national cross-station radio ad campaigns in Germany. Directly comparable to ad.audio as a national audio advertising marketer; however, RMS primarily covers FM networks whereas ad.audio owns DAB+ and programmatic.
• AS&S Radio GmbH: AS&S Radio is Germany's leading radio marketing company, selling audio advertising inventory on behalf of major public and private broadcasters. Directly comparable to ad.audio as both monetize radio advertising inventory for German advertisers, though AS&S focuses more on traditional FM and audio networks while ad.audio is focused on DAB+ and programmatic.

Broad incumbents

• Spotify Ad Studio: Spotify's self-serve and managed advertising platform serves audio ads to its global streaming user base with targeting and measurement. Adjacent competitor for digital audio advertiser budgets in Germany, competing for share of the audio ad spend that might otherwise flow through ad.audio.
• SoundCloud: SoundCloud operates an audio creator platform with a programmatic advertising offering (SoundCloud Advertising) targeting streaming and creator-content audiences. Competitor for digital audio advertiser budgets; operates globally rather than regionally focused on German DAB+.
• Ströer Media Deutschland GmbH: Ströer is one of Germany's largest out-of-home and digital media sales houses, and a strategic partner of ad.audio via its SSP that powers ad.audio's Programmatic Radio integrations. Comparable as a German media sales platform for advertisers and agencies, though Ströer operates across OOH and broader digital channels rather than specializing in audio.
• Antenne Deutschland GmbH & Co. KG: Antenne Deutschland operates national DAB+ platforms and produces radio programs (including the Absolut Radio senderfamilie distributed via ad.audio). Closely related as the broadcaster whose inventory ad.audio exclusively markets. Comparable in the German digital radio value chain, though Antenne Deutschland is the content/originator side whereas ad.audio is the ad sales/marketing side.

Others

• Radiozentrale – Verein privater Rundfunk & Telemedien: Radiozentrale is the marketing association of German private radio broadcasters, providing cross-radio marketing for the medium of radio. Thematically comparable to ad.audio in promoting audio advertising effectiveness, though operates as an industry body rather than an inventory seller.
• Mediaplus / Serviceplan Group: Mediaplus is a major German media agency within the Serviceplan Group, and a strategic GTM partner for ad.audio — Mediaplus implemented the ATU Programmatic Radio case study cited in the data. Ecosystem adjacency: a media agency buyer rather than competing inventory seller, but a key customer relationship for ad.audio's distribution.
