Milan, 27 August 2022 — AdTonos, a full-stack programmatic audio advertising platform, announces a new funding round led by BlackSheep MadTech Fund. The company reports 10× year-on-year growth, making it one of the fastest-growing audio AdTech companies in Europe.
The investment was covered by Il Sole24Ore under the headline: "Il fondo BlackSheep (Eureka! sgr) punta sulle pubblicità audio di AdTonos".
AdTonos is BlackSheep's fourth investment in less than a year, demonstrating the pace of deployment and conviction around the audio advertising opportunity.
Why BlackSheep invested in AdTonos:
- Audio is the fastest-growing digital ad format — podcast, radio, and streaming audio audiences are expanding rapidly, but monetization infrastructure has lagged far behind video and display.
- Full-stack vertical platform — unlike horizontal programmatic platforms that treat audio as an afterthought, AdTonos is built audio-first, with proprietary solutions for publishers (radio, podcasts, streaming services) and advertisers.
- Interactive audio advertising — AdTonos' Twilight solution enables voice-activated interactive audio ads for streaming platforms and AI assistants like Alexa and Google Assistant — a genuinely differentiated format.
- SdkSandStorm — the company's mobile audio advertising SDK is transforming contextual targeting and monetization in mobile gaming and app environments.
AdTonos is headquartered in London and operates across Europe and the US, serving major publishers and advertisers across all audio environments.
