This year's Web Summit at the RDS could be the last one to be held in Dublin, according to the event's founder Paddy Cosgrave.

Cosgrave said at the launch of the 2015 Web Summit on Wednesday morning that a number of cities are interested in taking the event out of Ireland, but that no decision has been made yet. This year's event will play host to some of the biggest names in tech, sport, literature and more. Pixar founder Ed Catmull, Tour de France winner Chris Froome, The Da Vinci Code author Dan Brown and Tinder CEO Sean Rad will all be in attendance in Ballsbridge between November 3rd and 5th. Mike Krieger, the founder of Instagram, will also be present among the 650 speakers expected to share their wisdom at "the most important gathering of start-ups on the planet," according to Cosgrave. More than 30,000 people are expected to attend the event, with over 2,000 start-up companies and 1,000 investors descending on Dublin 4. From its humble beginnings in 2010, when the attendance was 400 - all of whom will return to the event for free this year - the Web Summit has seen start-ups raise on average €391,448 each and Cosgrave is excited at the prospect of putting together the biggest event yet. "Dublin will be home to three days of legendary networking, inspirational stories and ground-breaking innovation. I can't wait," he said.
