Tech City: facts and figures Tech City is located in and around Shoreditch and Hoxton, east London. Often referred to as Silicon Roundabout, due to the Old Street roundabout that lies at the heart of the area. The area began as a technology hub in 2008, but was given a major boost in late 2010 when David Cameron announced plans to accelerate growth of the area. South African entrepreneur Eric van der Kleij was named as the first chief executive of Tech City a year later. He has since left. Companies in and around Tech City include Expedia, Twitter, Eventbrite, PBS, Airbnb and Amazon. In March this year, George Osborne, the Chancellor, opened Google Campus, a new centre offering office space to start-up companies. The Campus also provides mentoring to young entrepreneurs, and is home to SeedCamp, an early-stage investment programme.
