Tech Track 100

Etherstack designs software for radios used by the police, emergency services and the military. Its technology allows, for example, one army to communicate on a secure channel, while another channel is used to talk to an allied army. The London company has no British customers and most of its turnover is generated in America and Japan. Founded in 2002 by group chief executive David Deacon, it was the first non-American business to receive funding from the CIA’s venture-capital arm in 2007. Sales grew 44% a year from an annualised £3.7m in 2007 to £11.1m in 2010.
