Sledge, who were recently awarded a two-year extension to its contract with O2 (the trading name for Telefónica), said that Campus Party Europe will be one of its biggest projects to date with the brand.
The event will take place from 2-7 September 2013, engaging 10,000 delegates per day across Europe about the possibilities of new and emerging technology. Campus Party is aimed at people interested in digital technology as well as, 'techpreneurs', hackers, developers, gamers and geeks.
The event will encourage entrepreneurs, industry staff and students to embark on or progress in digital careers, with advice for industry on how to keep up with the latest developments in digital.
The event's eight stages will welcome more than 100 speakers and more than 500 hours of content across five days. Speakers at previous Campus Party events include Tim Berners-Lee, the inventor of the World Wide Web; Steve Wozniak, co-founder of Apple; and astronaut Neil Armstrong.
Ronan Dunne, CEO of Telefónica UK, said: "Since 1997 tech fans across Europe and Latin America have flocked to Campus Party in their thousands to innovate, learn and engage with some of the biggest names in technology. This year we’re injecting even more ambition and more scale into an already huge event.
"The marketplace will feature a huge range of free support services, including advice on how to get your foot on the career ladder or how a business can succeed on Facebook. The event will help people hone and develop their digital skills whilst giving businesses of all sizes the opportunity to find the talent they need to grow."
Sledge CEO Nic Cooper said: "Campus Party is a great opportunity for us to be involved in a truly unique event within the digital industry, not only in the UK but within Europe."
Sledge also works with Department of Business, Innovation & Skills, UK Trade & Investment and the Technology Strategy Board.
