13. DSGi Business - £200m-plus
The Dixons-owned VAR is still something of a mystery; its owner has not broken out revenues for its B2B division for several years and, as it did last year, the company declined to provide us with a figure. Our most educated guess remains that the combined operations of Equanet and PC World Business add up to something more than £200m. This year has been a typically eventful one for the company, beginning with 77 staff being placed on redundancy notice. Change was also afoot at the top of the tree, with boss Phil Birbeck departing after two years. His replacement, Felix Stauber, becomes the fourth leader in the space of about four years.
