New owner Phil Doye stamped a new identity on this York-based software licensing specialist on 1 September 2020, rebranding it from SBL to boxxe in a move he said "supports our intentions to innovate within our own market". The defence specialist hasn't filed any new numbers since last year, but told us revenues reached £273.6m in its 16-month period ending 31 December 2019, a 47 per cent like-for-like hike.
