WiredUK recently mapped the UK’s technology startups based around London’s answer to Silicon Valley: Old Street’s ‘Silicon Roundabout’.

Sponsored by Kodak and The Next Web, Techfluff.tv decided to delve a little deeper into London’s startup scene and video interview ten of these companies.

This week we meet Alex Halliday, co-founder of SocialGo, a service that allows you to create a custom social network in minutes. Alex discusses the service, its success in the USA, the attraction of being based in Old Street and SocialGo’s plans for the future.

The Silicon Roundabout series is filmed on a Kodak Zi8. You can watch previous episodes here.
