THEY are the cream of the technology crop in Ireland, and today they are descending on the RDS in Dublin for this year's Dublin Web Summit.
The two-day summit aims to bring a host of start-up companies seeking finance and potential investors together.
There will also be a number of presentations and conversations featuring some of the biggest names in the industry.
The event opens with Patrick Collison, the Limerick native who along with his brother is now running Stripe, a multimillion euro payments firm based in Silicon Valley.
Some 3,000 people will attend the event, which has mushroomed from just under 600 people when it started two years ago.
This year the event will feature four stages, with three of them focused on developing apps, digital marketing and cloud computing.
All five-star hotel rooms in the capital are booked out for the next three nights while most of the four and three-star rooms are taken as well. By some estimates, the summit will be worth €12m to the local economy.
The Web Summit will be followed by the Founders event, which kicks off tomorrow night and continues until Saturday.
A Davos-style closed-doors event for some of the biggest names in world business, this year's Founders will feature, among others, Jawed Karim, one of the men behind YouTube; and Skype founder turned venture capitalist Niklas Zennstrom.
The events are the brainchild of Wicklow native Paddy Cosgrave, who started the meetings almost on the back of a napkin in 2010.
