About Vianet

Vianet Group capture and process operational data to produce critical insight, analysis and actionable information enabling customers to transform business performance.

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

Servicing over three hundred customers across the world and rendering live data to our IOT platform from a footprint of over 210,000 connected devices daily, Vianet is one of the largest business to business 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 to a customer's asset or system. The device then sends data back via our IOT platform to cloud based servers. The flexibility and functionality of the device means the technology can be applied to any machine which has the capability to output data. In our award-winning end-to-end solution the device is also used to connect our contactless payment solution and communicate payment terms to our cloud-based payment services providers.

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 via a single 4G LTE communications hub. The technology was originally developed for beverage and asset management in drinks retailing but can be used with any data gathering device with a digital output such as gaming machines, utilities management. and POS.
