Managing director Piers Daniell founded this high-speed internet service provider in 2004. Initially he funded it with his credit card, but two years later he bought his own network with a £150,000 investment from a business angel. He attributes growth to word-of-mouth referrals and, while the company does not promise perfection, it does guarantee no more than 0.01% downtime. Customers range from the Church of England to Revolution Bars, and sales rose 45% a year from £1.6m in 2008 to £5.1m in 2011.
