Mobile software tools company Appcelerator has opened an EMEA head office in London to support its growing business in the region. Appcelerator said the move is in response to its expanding user base in the region – which has grown by more than 110 percent over the past six months – as well as a number of significant customer wins in Western Europe.

The company is also confident that the European mobile app market will continue to grow rapidly with France, Germany, Italy, Spain and the UK all expected to drive mobile ad revenue to more than a billion dollars by 2014.

VP and managing director of EMEA, Doug Norton-Bilsby, will lead sales and operations and expand the core team for sales and delivery in the region. Norton-Bilsby was previously Experian’s head of sales and marketing for EMEA and India and has previously worked for Infor and Cognos.

The company announced in November that it had secured US$15 million in Series C funding from a variety of investors including eBay and Red Hat.
