Add connectivity.
Not telecom overhead.
Adding connectivity to a product can unlock new revenue, better customer experiences, and entirely new services. But getting there often means navigating carrier relationships, fragmented APIs, provisioning systems, billing infrastructure, and telecom operations that were never designed for modern product teams.
- 01
Multi-operator connectivity is fragmented
Different networks come with different contracts, pricing models, APIs, coverage, and operational workflows, making expansion slower and harder to manage.
- 02
Connectivity adds a new operational layer
SIM and eSIM provisioning, activations, plan changes, usage tracking, subscriptions, inventory, and support all need to work reliably behind the customer experience.
- 03
Billing gets complicated fast
Carrier costs, customer pricing, subscriptions, usage, markups, invoices, and reconciliation often live across separate systems, making margins and costs harder to understand.
One connectivity platform. Many ways to build on it.
Whether connectivity powers your product, your customers, your workforce, or your AI agents, Spenza gives you the infrastructure to launch, manage, bill, and scale it from one platform.
Manage thousands of connected devices across multiple carriers
Pool plans across operators, automate lifecycle changes, monitor usage, and control connectivity costs across your fleet.

Three ways to get connectivity. One of them scales.
Most teams evaluating Spenza have already run one of the first two approaches. This is the comparison that decides it, so we have set it out in full rather than leaving it to a sales call.
ONE PLATFORM, FOUR HUBSAlready working with carriers or running your own stack?
You don’t have to start over. Keep the carrier contracts, customer relationships, and systems that are working today. Bring existing connectivity into Spenza, move selected operators or workflows first, and migrate at your own pace.
What changed after
they moved to Spenza.
Three business models, one platform. Each story shows where the team started, what they moved, and what changed.
All case studies
Butlr
Faster time to market for a new country, against their previous carrier process.
- STARTING POINT
- New countries launched through their previous carrier process.
- WHAT MOVED
- High-bandwidth plans for smart building sensors across the US, UK, and France.
- WHAT CHANGED
- All three markets on one invoice, at lower total telecom cost.
Multi-country connectivity stopped being an operational burden and became a strategic asset.
Angel Watch
For the watch and its connectivity plan, priced for a watch rather than a phone.
- STARTING POINT
- Connectivity for a child's smartwatch, on pricing built around phones.
- WHAT MOVED
- The plan moved into the Shopify checkout, sold alongside the device.
- WHAT CHANGED
- Watch-priced connectivity, lower cost per line, and a branded activation flow.
Connectivity stopped being a cost centre and became a competitive advantage.
RocketPhone
A branded business mobile network launched on Spenza, with no telecom stack of their own.
- STARTING POINT
- Calls placed from a rep's handset never touched RocketPhone's platform, so they never reached Salesforce.
- WHAT MOVED
- Carrier integration, eSIM provisioning, rating, billing, subscriber management, and multi-tier reseller control, all over API.
- WHAT CHANGED
- Native mobile calls terminate to a SIP URI inside RocketPhone, recorded, transcribed, and written to Salesforce.
Capturing a native cellular call means controlling the voice path. There is no software shortcut.
Faster to launch a new market than building the carrier stack yourself
Countries with local operator access
Pre-built operator integrations
Typical connectivity cost reduction after routing and plan right-sizing
Connectivity should be a line in your config, not a year of your roadmap.
Carriers built their systems for handsets and monthly consumer plans. Everything since — a sensor in a shipping container, a watch on a child, an agent answering a support line — has had to be bolted onto that model one contract at a time.
Spenza exists so that work happens once, in one place, and every team that follows inherits it. That is the whole thesis, and it is why sourcing, cost, billing, and voice sit on a single data model rather than four products with a shared logo.

What is an MVNE, and what does Spenza actually do?+
An MVNE is the technical and commercial stack a company runs an MVNO or a connectivity business on, without owning network infrastructure. Spenza is that stack in four parts: operator sourcing and eSIM routing (TelecomHub), cost intelligence across every line and invoice (ControlHub), branded plans, checkout, billing and support (UXHub), and phone numbers, SMS and voice for AI agents (AgentHub). One data model, one API, one invoice.
Who runs on Spenza?+
Device makers and IoT fleets, consumer brands selling a subscription alongside hardware, MSPs and resellers running an MVNO, travel eSIM brands, AI product teams that need a real phone line, and enterprises replacing phone stipends with managed lines. Angel Watch, Butlr, MSP-A, and Daito are on the platform today.
How does Spenza handle IoT fleets at scale?+
Over API. SIM and eSIM provisioning in bulk, usage monitoring per line, threshold alerts, over-the-air operator switching with no physical SIM swap, and fleet-wide operations. LTE-M, NB-IoT, Cat-1, and LTE run across every aggregated operator.
Can we keep our existing carrier agreements?+
Yes. Use the operators Spenza has aggregated, bring your own contracts, or combine the two. Every line shows up in the same dashboard, API, and invoice.
Can we give an AI agent a real phone number?+
Yes, through AgentHub. Provision a local or toll-free number in 40+ countries, attach it to an agent, and handle SMS, voice, and realtime audio streaming over the same API and the same billing rails as the rest of your connectivity.
How fast can we launch, and how is it priced?+
Teams reach live service roughly 88% faster than building the carrier stack themselves, with two to three engineering hours of integration. Pricing is per line, with volume tiers for large fleets. The calculator gives an estimate; a demo gives a projection for your fleet.
