Marlow-based Softcat was founded in 1993 by Kelly as a mail order software company for the business-to-business market. It's now morphed into a full-service IT provider that specialises in the public sector. It's a fast-growing operation that has won some hefty orders of late. In 2012-13 it made £28.2m profit on £395.8m sales. In 2013-14 it is set to take sales to £470m. Kelly now takes a back seat, having handed over the chairmanship in 2012. Softcat regularly features in the Sunday Times Best Companies awards and is planning to open its fifth regional office, in Leeds, next year.
