Ten new start-ups have joined Vodafone's xone accelerator programme.

Xone is a six-month accelerator programme that runs out of Vodafone's South Island headquarters in Christchurch. The programme is now in its second year.

Each of the companies taking part get $25,000 in seed-funding and an option to use space at Vodafone's Christchurch offices if they are based in the region. They all take part in regular monitoring sessions in Christchurch and have access to Vodafone's global partner network.

Vodafone doesn't take any equity in the Xone start-ups. It focuses on picking companies operating in areas close to Vodafone's main lines of business. There's a pronounced emphasis on mobile.

This year's programme members include start-ups working in areas such as the Internet of Things, sensors, drones and artificial intelligence.

Vodafone says they come from a diverse range of sectors including wine-making and pipfruit growing. One start-up, Christchurch-based Evnex, builds charging technology for electric vehicles that integrate with solar smart-grids. Parkable, connects parkers to hosts with spare land.

The first wave of xone companies went through the programme last year.

Xone head Nicole Buisson says the ten start-ups from 2016 have generated more than $8.5 million in new revenue, attracted $7 million in funding and have created 25 new jobs. They now have operations in 12 countries.
