The co-founder and chief executive of construction technology software start-up Mastt has earmarked expansion in the US and Middle East as top priorities, as a booming construction sector and rapid revenue growth has led investors – including the founders of big money local success story Aconex – to pour almost $10 million into the company.

The $9.5 million funding round comes a year after it closed a $2.2 million funding round. The latest was led by venture capital firm OIF (Our Innovation Fund) Ventures, with money also from Artesian, Significant Early Venture Capital, Investible and Gravel Road Ventures, and the fund of Aconex co-founders Rob Phillpot and Leigh Jasper.
