As a resident of Hackney, Fi Glover has been fascinated by the way her home patch is being turned into one of the world's most important internet start up centres. Old Street Roundabout has been renamed Silicon Roundabout. In this series of One to One she talks to the men and women responsible for this boom. She wants to know more about this generation of tech gurus, as part of our economic future lies in their hands and in their dreams. In this final programme in her series she talks to Tom Allason, chief executive of Shutl, a courier business that's grown 50% month on month since it started two years ago. Tom explains that it's his past failures that have led to his present success. Fi begs an invite to his exit event. Producer: Lucy Lunt.
