Who are the tech stars attending this year's Dublin Web Summit? Among the 10,000 people attending this year's conference, there are a few prominent names in the online world.
First among equals is Elon Musk, the founder of electric car company Tesla Motors, which has rocketed in valuation over the last 12 months. Mr Musk (left), who is also a co-founder of Paypal and the private space exploration firm SpaceX, already has iconic status within the tech industry at the age of 42.
After Mr Musk comes Drew Houston (below), co-founder of Dropbox, the online sharing and storage service commonly used by smartphone owners. Mr Houston's company recently set up a European base in Ireland, which is growing quickly.
Some returning tech icons, such as Skype founder Niklas Zennstrom are also present. Other tech companies well known to Irish people but not yet tech titans are also here, such as taxi-app firm Hailo's co-founder Jay Bregman.
Some of the Web Summit's most influential attendees have a relatively low profile in the layman's world. For example, online ad service DoubleClick's co-founder Dwight Merriman is now one of the most pivotal figures in online database technology through his new firm 10gen, creator of MongoDB.
Otherwise, high-profile speakers include celebrity skateboard entrepreneur Tony Hawk (above) and Evernote chief executive, Phil Libin.
