Every year for the last decade Deloitte has compiled their Technology Fast 50 list, showing which companies have experienced the highest growth in revenue in the preceeding three years.

This year’s winner, Vocus Communications, experienced an astonishing 11,306 percent growth. Their CEO, James Spenceley, said they have made their mark as the “Internet provider for Internet providers” — it’s a pure wholesale play that has grown quickly by keeping things simple, servicing customers well and avoiding employing people who are empire builders.

I talk to James on today’s BTalk, along with Joshua Tanchel, who is the leader for the Fast 50 porgram at Deloitte.
