Who we are
Plumma SRL is based in Bologna and builds Plumma Connect, a Network Signal Orchestration layer running in seventeen countries across four regions.
What we hold to
The reachable footprint is the union of every path under contract, so it grows without the client renegotiating anything. Every statement about it names the operators, or names the percentage with the base it is a percentage of. A percentage without its denominator does not ship.
Claimed where it is true, which today means the enterprise licence and not the published self-serve price. On the published price there is a margin by design, and we say so on the page that sells it.
Offered as an object rather than described as architecture. The difference is between saying we have a consent and audit architecture, and handing your reviewer the dossier before their review opens.
No rebate, no volume kickback, no marketing development fund, at any size. Where a supplier will not permit per-call cost disclosure to the client, the supply is declined and the gap is declared. That costs coverage, and it is the decision that keeps the rest of this coherent.
The credential, with its qualifier
Plumma is a GSMA Open Gateway channel partner, named in the programme's May 2026 cohort. More than sixty parties hold channel partner status worldwide, so it is a credential rather than a moat, and in that cohort Plumma was the party working Italy. We state it that way because the alternative is an exclusivity claim, and the GSMA's own partner map would contradict it.
Written about elsewhere
The GSMA's own programme page records the channel partner appointment and what it covers in Italy. API Evangelist read the interface rather than the pitch, and wrote about how the layer carries CAMARA's vocabulary without putting its endpoints in front of a customer. We link both because a reader should be able to check the claim against somebody who does not work here.

Everything a supplier onboarding form asks for is on this page and repeated in the footer, so nobody has to request it.
When something breaks
Routing layers fail. Operators change a version without notice, a supplier has an outage, a normalisation rule turns out to be wrong for one edge case. When that happens in public, silence is the posture failing its first test.
The same nine we think every vendor in this category should have to answer, ours included. Four of ours turn on artefacts we have designed and not yet shipped.
