About Vianet

Vianet Group is a leading provider of actionable management information and business insight created through combining data from our Internet of Things ('IOT') solutions and external information sources.

Since its Admission to AIM in 2006, the Group has grown from its core beer monitoring business both organically and through strategic acquisitions to widen its offering and develop new businesses, especially in vending telemetry and contactless payment solutions particularly for the premium coffee sector.

Servicing over 300 customers across the world and rendering live data to our IOT platform from over 250,000 connected machines daily, Vianet is one of the largest business to business (b2b) connected solutions providers in Europe with established long-term relationships with blue chip customers and growing recurring revenues which are over 85% of our total revenues.

In our Smart Machines division, we connect a single data gathering device with its own on-board communication capability to a customer's asset or system. The device then sends data back via our IOT platform to cloud based servers. The technology was originally developed for automated retailing machines; however, the flexibility and functionality of the device means the technology can be applied to any machine which has the capability to output data. The device is also used to connect our contactless payment solution and communicate payment terms to our cloud-based payment services providers where that application is also required.

The Smart Zones division is where we connect multiple data gathering devices into one or more systems or assets with the data from those devices being communicated back to our IOT platform and cloud-based servers via a single 4G communications hub. The technology was originally developed for flow monitoring devices, temperature sensors, and asset management in drinks retailing but any data gathering device with a digital output could be connected to the communications hub where required such as gaming machines, utilities management and POS.
