Prime Minister David Cameron visited a Shoreditch digital business hub yesterday, when he hailed the phenomenal success of Tech City and pledged the government’s continued support.

Mr Cameron’s made his appearance a year after announcing his vision to accelerate the East London digital hub, there last November.

“Tech City” stretches from Shoreditch to the Olympic Stadium and is centred around Old Street’s “Silicon Roundabout” – named after California’s Silicon Valley, home to the world’s largest technology corporations.

During a visit to The Trampery in Bevendon Street Mr Cameron unveiled a new Tech City Map, showing the number of tech businesses there has trebled in the space of just one year.

There are now 600 compared to 200 last November and just 15 in 2008.

The map has been created by developers from Trampoline Systems, which is based in the Trampery – a cutting edge technology centre, designed to support a new generation of creative enterprises.

Designed by serious games developer Playgen, based nearby in Kingsland Road, the map includes analytics to highlight the flourishing community in East London, pulling in streams of social network data for all the technology business in the district to analyse their networks and influence.

The aim is to provide a data infrastructure to help the cluster of tech businesses grow even more.

The growth of the cluster was hailed by the Prime Minister, who said: “One year ago we made a major commitment to helping the tech cluster in East London grow.

“The successful growth we see today is thanks to the talented, creative entrepreneurs who have decided to set up there.”

To support the growth of businesses there, Cameron also announced the expansion of the Red Tape Challenge, so entrepreneurs and investors can let the government know when rules and regulations get in the way of innovation.

“As a Government, we are determined to continue doing everything we can to help support and accelerate this growth,” said Cameron.

“We have already taken action such as introducing the Entrepreneurs Visa and tax breaks like the Enterprise Investment Scheme, we are also looking at new ways we can protect Intellectual Property.

“But we are not done yet - we’re looking forward to continuing our work with the community in Tech City to further support them to grow.”
