Smile Invest has acquired a majority stake in RB+ (https://rbplus.nl/), alongside management and founder Robert Bijlsma. This marks Smile Invest’s third investment since the beginning of 2025, following earlier participations in Digitopia and iPractice. Smile Invest now partners with seventeen innovative growth companies across the Benelux, each a leader in its respective market.

RB+ specializes in the design, production, installation, and maintenance of passive structural fire protection for (non-)residential renovation and new construction projects. The company offers comprehensive solutions that ensure optimal fire safety for buildings in sectors such as healthcare, utilities, and residential housing. RB+ is known in the market as van der Aa, Firejob, and Preficon—serving the entire value chain of passive fire protection. With innovative, digital solutions, RB+ delivers the most complex and demanding projects that comply with increasingly stringent regulations regarding the installation and documentation of structural projects. Clients praise RB+ as a knowledge center and pragmatic partner in the design and execution of highly complex challenges.

Robert Bijlsma, CEO of RB+: “I’m proud of what we’ve built with our team and look at the future with great confidence. With Smile Invest, we’re bringing on board a strong and like-minded partner who shares our vision and supports us in the next phase of growth. Their experience and network enable us to further professionalize our innovative and digital solutions, strengthen our position as market leader, and—through DNA-related acquisitions—expand our profile within the fire protection industry, from design to full-service solutions!”
