blitzfon exists for one reason: business calls fail when numbers are borrowed. We built the carrier we couldn’t buy — own number ranges, own infrastructure, analytics that tell the truth.

blitzfon started inside call centers, not outside them. The teams behind it ran outbound floors and watched the same thing kill every campaign: numbers flagged as spam because three resellers sat between the caller and the network.
So we became the network. Today blitzfon holds and operates its own number ranges in Germany, Austria, Switzerland and nine further markets — and layers a cloud PBX, Microsoft Teams calling and AI call analytics on top, so the people running the floor see what the network already knows.
Two brands, one platform: blitzfon.de is the registered German carrier for local business. blitzfon.com is the international carrier for teams that dial the world.

Blitz Fon, Ltd. — the company that holds the licenses, the number ranges and the infrastructure.
Registered with the Bundesnetzagentur as a telecommunications network operator.
Own ranges across 12 markets; vetted partners everywhere else. We say which is which.
Cloud PBX, Microsoft Teams Direct Routing, AI transcription and analytics — one account.
If we sell it, we can point at the hardware or the contract behind it. No borrowed claims.
Uptime, pickup rates, answer rates — published as numbers, not adjectives.
No invented logos, no fake testimonials, no “trusted by thousands”. The network is the proof.

Bring one campaign or one team. We put them on clean German numbers with full analytics. You judge the next two weeks by the numbers.
