With 23 regional offices in the UK and Ireland, this Leamington Spa-based outfit bills itself as CAD vendor Solidworks' largest UK reseller. Following two big acquisitions in 2016 and 2017, Solid Solutions characterised 2018 as a year of consolidation and integration. Despite this, revenue rocketed by a quarter, with net profits swelling from £4.1m to £6.7m. During the period it invested in a newly incorporated 3D print reseller, Solid Print3D.
