The Grupo Oplena behind emRadios
emRadios brings together radio stations from all over the world in a visual, interactive experience — and it is a product of Grupo Oplena, a technology ecosystem that conceives, builds and operates its own digital products. From backend architecture to the final user experience, every product is built in-house, with a focus on quality, scale and attention to detail.
Our own products
We don't outsource the core: we conceive and build each product end to end.
Full stack & cloud
Backend, frontend, data and cloud infrastructure under one roof.
Scale and operations
We take products live and run them — we don't stop at the prototype.
Connecting stations, listeners and advertisers
emRadios exists to close a gap: thousands of stations are on air right now, and listeners around the world will never find them. The platform brings both sides together — and opens a third bridge, to those who want to advertise on those stations.
We do not alter the broadcast
The player opens the same public stream URL the station itself publishes, exactly as a browser would. We do not host, record, re-encode or insert anything into the audio — no advertising before, during or after. What you hear is exactly what the station broadcasts.
The station owns its page
Every station is invited individually and decides whether to appear. Name, logo, description and contact details are theirs, and leaving is immediate: one email and the page comes down, no questions asked. We claim no rights over signal, brand or content.
Listeners worldwide
The catalogue is open and free for listeners, with search by name, city and country, a map and an app. A local station becomes findable by someone on the other side of the planet — and by those who moved away and want to listen from home.
Advertisers reach the right stations
Advertisers find stations by region, audience and format. The station sets its own price, accepts or declines each campaign, and receives in full what it quoted — our commission is added on top and paid by the advertiser, never deducted from the station.
