iono.fm

iono.fm is an online audio platform based in Cape Town, South Africa, providing podcast hosting and radio live streaming services. Founded in 2008, it was built to serve developing markets by offering audio delivery at low data rates, and it has distributed podcasts to millions of users across sub-Saharan Africa on mobile networks. In 2015 the company added a radio streaming service to extend similar low-data benefits to broadcasters.

The platform serves customers ranging from large radio stations to individual podcasters, supporting multiple shows and users under a single account. It offers dynamic ad insertion with country-level geo-targeting, multiple audio bitrates, loudness normalisation, and a customisable, embeddable web player for episodes, shows, publishers, and live streams. Radio streaming customers receive unlimited simultaneous listener capacity, detailed listener analytics, automated downtime and dead-air monitoring, and streams published in multiple formats for compatibility.

iono.fm also operates a public podcast discovery site where listeners can browse an extensive library of shows from a wide range of publishers, build playlists, follow shows via RSS, and download episodes. Additionally, the company provides an audio advertising product that uses its dynamic ad insertion engine to help advertisers reach podcast and radio listeners, supporting flexible campaign budgets. The company positions itself as serving premium publishers and radio stations in developing markets, emphasizing reliability, reporting, and customer support.
