International innovation festival OpenCo is expanding outside of the US for the first time today, with 50 leading London tech firms set to open their doors and provide a glimpse of their inner workings.
The festival officially launched on 6 June at a speclal event at Google Campus, the search giant's East London startup hub and co-working space.
There, OpenCo founder John Battelle introduced London to the event, describing it as "a mash up of an artist's open studio and a tech conference with the atmosphere of a music festival."
"We spun this up with a conspiracy of good. Good people wanting to do good things for a good city and celebrate what's happening in this economy," he added.
"There is a movement happening. The Internet is stimulating the recovery in most countries. London here is the hub and nucleus of it all," added Joanna Shields, Tech City Investment Organisation CEO.
In addition to Google Campus, some of the companies set to offer a behind-the-scenes look at their operations on 7 June include Yahoo, Yammer, Spotify, Mubaloo, Songkick, Outbrain, and Wayra.
OpenCo said that it was committed to coming back to London in 2014 and was also looking at expanding to Shanghai and Berlin next year. Detroit will be the fourth city to get an OpenCo festival later in 2013 - companies in San Francisco and New York also participate in the event.
OpenCo London 2013 is running in partnership with LeWeb 2013 and has been backed by the Tech City Investment Organisation and the Mayor of London's Office.
"Throwing open the doors of these enterprises is a great way for enterprises big and small to foster collaboration and build links with their communities. OpenCo is a great concept and I hope it will be a huge success," commented Boris Johnson, Mayor of London.
