This year's Web Summit could be the last in Ireland.

Organisers say that they are in talks with a number of cities.

Web Summit CEO Paddy Cosgrave says that they have spoken to a number different cities about hosting the event in the future.

"I would say very openly that since the very first event in Ireland we have been approached," he said.

"In 2011 we had a number of meetings in number 10 Downing Street and the number of countries and cities involved in the Web Summit has grown substantially in the past few years".

30,000 people are expected at the RDS in November for Web Summit – which features 2000 start-ups, over 1,000 investors and could be worth over €100 million to the economy.

This year's speakers include 'Da Vinci Code' author Dan Brown, Tinder’s Sean Rad, Instagram's Ed Catmull and Tour De France winner Chris Froome.

The group says since 2010, start-ups attending the Web Summit have raised on average €391,448 each.

There will be 21 summits over nine stages this year - with a number of new stages dedicated to fashion, health technology and content.

Mr Cosgrave told the Pat Kenny Show here on Newstalk the issue of reliable wi-fi - which has been contentious in previous years - is crucial.

Mr Cosgrave also recently made headlines after he apologised for mistakenly taking credit for other people's work.

During an interview in Amsterdam, he was asked what made the Web Summit special.

His response was that in taking a different approach to organising conferences, they try to build as much of the software themselves.

"Even the ticketing app that we use I built. It's used by dozens of conferences around the world like XOXO and Brooklyn Beta", he told the interview.

He then wrote a blog post, clarifying: " The ticketing app I was referring to that we use at Web Summit is Tito. It's an incredible product that was built by Paul Campbell, Doc Parsons and their fantastic team".

Brooklyn Beta was a conference that ran for four years and was an early Tito beta customer.

"XOXO is a highly-praised indie festival held in Portland every year, organised by Andy Baio and Andy McMillan. They built a registration process for their own unique needs three years ago", Mr Cosgrave said.

"I claimed credit for the work of Paul, Doc, their team and Andy Baio and Andy McMillan and their team. For this, I apologise", he added.
