LEO 1 became a model for outsourcing, being used by Ford UK and the Met Office for computing jobs. In November 1954 Lyons formed Leo Computers Ltd to build business computers to order, producing the LEO II in 1957. Organisations that used LEO II computers included Stewarts & Lloyds, Ford and the Ministry of Pensions.
