These are London's 20 fastest-growing tech companies

There’s good reason that politicians, economists and entrepreneurs alike all seem to be so enormously excited about the potential of technology to drive growth.

The UK’s 50 fastest-growing tech companies boast an average five-year growth rate of a staggering 1,382%, according to Deloitte’s Technology Fast 50 index.

Together, those businesses generated £672m in total revenues in the year 2012/13 and provided more than 5,000 people with jobs.

London is at the heart of all that growth and innovation. Some 40% of the top 50 companies are based here.

And the London companies that made the cut are punching above their weight in terms of economic contribution too, accounting for 47% of the combined revenues.
