Fremen
Broadcast infrastructure that works in impossible conditions.
We experiment relentlessly, then deploy only what's proven. The result: autonomous radio running years without intervention, remote broadcasts from locations without reliable connectivity, audio processing meeting standards automatically.
What we build
Three things, done well.
Most of what looks like infrastructure is held together by hope. We design for the cases hope runs out.
01 · Radio automation
Years without intervention.
Autonomous playout that survives power loss, network loss, and operator absence. Used in national broadcasting and state crisis communications.
02 · Remote broadcast
Stable signal where networks aren't.
Field-tested SRT, redundant transports, and recovery behavior built for places where the connection is the unreliable part.
03 · Audio processing
Standards met automatically.
EBU R128 and ATSC A/85 compliance, broadcast-grade normalization, three-click workflows. Same engine engineers respect, simple enough to hand to anyone.
New · Podcast hosting
Castcore. Your show, hosted properly.
Independent podcast hosting from the team behind Fremen's broadcast infrastructure. Fraunhofer AAC encoding conformed to spec, EU data residency, and publishing with zero latency.
01 · Audio
Conformed to spec, automatically.
Every episode measured with R128 methodology, encoded with Fraunhofer AAC, and conformed to the AES77 −18 LUFS target with a −5 dBTP ceiling — the same processing chain a national broadcaster runs.
02 · Publishing
Published on the second.
Schedule a release and it goes live the moment you picked, not whenever a nightly batch job gets to it. Your release window is a commitment.
03 · Business model
Your audience is yours.
No ad network, no listener data sold. Castcore's only revenue is your subscription — standard RSS means you can leave any time, and your audience comes with you.
🇪🇺 Every byte stored in the EU. Migrate from any host in an afternoon. Castcore is a Fremen product.
Our software
Tools we use ourselves.
Each product solves a problem we hit first. We ship them when they're worth handing to someone else.
How we work
Experiment relentlessly. Deploy only what's proven.
If it has to run for a decade in a building no one visits, it has to be boring on purpose.
Broadcast doesn't reward novelty. It rewards predictable behavior under load — at 03:00, on a holiday, with a flaky uplink and no one in the room. Even on Mondays.
Our research shows up in our products only after it has stopped being interesting. By then we know what it does at the edges, what it costs to maintain, and what it will look like in five years.
That's why national broadcasters and crisis communications infrastructure pick us, then keep us.
Have something that has to keep running?
Tell us where it sits, what fails first, and what it costs when it does. We'll tell you whether we're the right people.
