Building technology businesses is a bit like designing Formula 1 racing cars. Deciding which parts to create in-house, which to ‘buy & build’, and then importantly fitting them all together to accelerate top line growth and generate synergies. Well, after the Shire Systems and Active Online acquisitions last year, we believe Elecosoft, a specialist developer of BuildTech software, is on track to achieve all three. Indeed, in this morning’s trading update the company said it had made an “encouraging” start to 2019, with Q1 revenues up 20% (22% constant currency).
