Browne Jacobson has advised Norway-based Milient Software AS, backed by private equity investor Monterro, on its acquisition of UK software provider Cubic Interactive Limited, trading as Rapport3. The move strengthens Milient’s foothold in the UK project management software market and forms part of its wider European expansion strategy.
Milient develops digital management platforms for architects, engineers, and other professional service firms. Rapport3 delivers a project and resource management system tailored to similar users, making it a strong strategic fit for Milient’s growing portfolio.
Browne Jacobson’s private equity team, led by Partner Gareth Davies and supported by Principal Associate Matthew Dorman and Associate Jonathan Bradley, provided legal advice on the transaction, with additional input from the firm’s tax and employment specialists.
Gareth Davies, Partner at Browne Jacobson, commented:
“Supporting Milient Software and Monterro for the second time on their UK expansion underscores a broader market trend: the growing confidence of overseas investors in UK tech. This transaction is a powerful signal that international capital continues to back the UK’s world-class technology sector. It has been a pleasure to work with the team again and see their continued growth into the UK market. Our wider Private Equity practice is acting on an increasing number of international deals year on year, and this transaction is another example of our leading position in the mid-market space.”
Simon Nystrom, Investment Manager at Monterro, added:
“We’ve been impressed by the quality and innovation within the British software sector, and Rapport3’s expertise and client base make this a highly strategic addition to our business. Browne Jacobson’s deep understanding of cross-border transactions and the UK market has been invaluable. This is our second deal together, and their commercial approach and technical excellence made the process seamless.”
The acquisition reflects continued investor confidence in UK software firms and highlights the growing interest of international funds in supporting the country’s expanding technology landscape.
