The fastest-growing business in this entire report, Dell Gold partner Solutionize claims that it will imminently smash the £100m revenue barrier after swelling its top line by more than six-fold to £41.9m in its year to 31 March 2020. Net profit vaulted from £400,000 to £3.5m. The Wakefield-based outfit hopes a graduate academy it launched this October will become its primary source of recruitment by 2022.
