The company, which is based in Cheltenham and Edinburgh and was formerly known as Target Print Direct, also reported a rise in profit before tax, from £408,000 to £538,000.

Brightsource managing director Peter Frings said the success, which includes an average rise in turnover of 60% per year for the past three years, came purely from organic growth.

"We are a knowledge company – we succeed by being smarter, and learning faster, than our competitors and by providing our clients with outstanding service," Frings said.

Brightsource's focus has expanded from print management to a wider range of direct marketing services, such as environmental audits. The Cello Group-owned company also won new clients in 2007, including Lloyds TSB, Resolution plc, and overseas aid charity CAFOD.

A complete set of report and financial statements for 2007 will be available at the beginning of March.
