The Web Summit is moving from Dublin to Lisbon.
The massively popular tech conference began here five years ago.
Just 400 people attended the Web Summit when it started in 2010.
The tech conference has since grown to be a massive event, attracting 22 thousand people and speakers like the founders of Twitter, Tinder and Instagram.
Earlier this month CEO Paddy Cosgrave admitted other cities had shown an interest in hosting the event.
Now he has confirmed he's taken the difficult decision to move it to Lisbon in Portugal in 2016.
It's a massive blow for Dublin businesses as last year's summit pumped 100 million euro into the local economy.
