Zingarelli succeeds Babelgum co-founder Erik Lumer, who will now focus on strategic product development.
Zingarelli previously worked at Vodafone, where he was global director of networks and service platforms, and he also served as an independent board member of Fastweb.
As its content platform grows, Babelgum says that it plans to grow to about 100 employees by the end of 2007.
The company said that its priorities for the next 9-12 months will be: building up its offerings of professional content, starting a marketing campaign (initially with English-language viewers), and getting advertisers on board.
'I can't think of a more exciting sector to be involved in at the moment,' Zingarelli said in a statement. 'Babelgum is right at the heart of a revolution in television, building a truly personal global media capable of delivering a huge amount of professional television quality content to millions of users around the world.'
Babelgum chairman and co-founder Silvio Scaglia added: 'We are now moving to phase two in the development of Babelgum. The core technology has been proven and whilst our focus right now is on bringing together compelling content, we will soon turn to user acquisition and advertising. Valerio's appointment is a reflection of that changing focus His knowledge and first-hand experience in managing the technical and operational demands of rapid and sustained growth are exactly what we now require at Babelgum.'
Babel Networks is a privately held company with headquarters in Ireland and offices in the UK, France, Italy and an office to opensoon the US.
