We are building a programmable mobile core network for IoT called stacuity FUSION - it will enable you to build, control and secure services on your own slice of the global mobile network.
Building Cranes

Building in progress!

A network built from the ground-up for developers as first-class citizens.

CPaaS principles applied to the mobile core.

Designed as a platform, not just a service.

Democratisation and delegation of configuration, control, observability, integration.


Meeting external interoperability requirements.

Protecting the underlying network from disruption and abuse.

Mitigating potential security and fraud risks.

Watch Mike Bromwich talk about our vision for stacuity FUSION, at the recent TAD SUMMIT 2022.

The problem:

Mobile connectivity has become the fabric of modern society and industry, yet it struggles to meet the real practical needs of innovators, developers and emerging applications.

IoT in particular demands enhanced security, agility, customisation, programmability and globalisation which current networks are ill-equipped to meet due to technical, operational and commercial constraints.

The powerful real time control, security and monitoring which developers have become generally accustomed to does not extend to the mobile network which is still rigidly defined, costly and cumbersome to change.

Existing mobile connectivity offerings often offer little more than a ‘dumb pipe’ with rudimentary control to turn services off and on, and to meter usage for charging purposes.

So, there is a gap...

Our solution:

stacuity FUSION is a new breed of mobile network which combines our own pioneering core technology with access to the global mobile coverage ecosystem, via strategic wholesale access agreements with mobile operators.

This programmable core mobile network virtualises connectivity and affords developers the powerful on-demand configuration, real time control and flexibility which they currently lack.

>For developers:

stacuity FUSION's secure, cloud-centric microservice-based architecture enables the creation of innovative services, with no need for prior telecoms experience.

>For IoT MVNOs:

By adopting stacuity FUSION on a white-labelled basis, IoT MVNOs can enhance their connectivity propositions, defend margins and accelerate growth.

>For mobile operators:

As an adjacent core network, stacuity FUSION can enhance  mobile operators' ability to innovate and differentiate their wholesale and B2B services.

So what...

...will be possible via stacuity FUSION?

Security – enforcing precisely-targeted policies (‘principle of least privilege’).


Manageability – move configuration from endpoints into the network, allowing central configuration through software.


Observability – monitoring of behaviour, load, anomalies, failures. Analytics, alerting, troubleshooting. Big (meta-)data, AI, ML.


Mobility – controlling roaming, responding to location changes, bearer changes (e.g. 3G/4G), geo-fencing.


Integration – seamlessly interact with endpoints as if they were local devices.


Agility – make changes in real-time, without operator involvement.


Environments – create multiple environments for different applications, customers, trials, experiments, DevOps lifecycle.


Routing/globalization – manage regional break-out, optimize routing, direct-to-cloud, device-to-device, policy routing, SD-WAN-style control.


Monetisation - innovative charging based on application, payload, location, tokenization/crypto.


Lifecycle – control device activation/suspension.

stacuity FUSION will be going live in the first half of 2023 - sign-up now to join our beta-trial.
