This storage integrator is in the minority in that it increased its profit margins in its latest year, despite complaining that its core business is coming under pressure from public cloud. Net profits came in flat at £2.1m in its year to 31 December 2017, even as revenues slid nine per cent. Headquartered in Stockholm, the wider Proact business employs 800 staff in 15 countries and claims to manage 100 petabytes of data in the cloud. Key vendors include NetApp, Dell EMC, AWS and Microsoft.
