Our History

Our journey began in a quiet village nestled in the foothills of Stirling, central Scotland. Starting with a couple of desks and a few scanners, arbnco began life as a small family business on a mission to digitize health and facility data. With the success of this business, and energized by an entrepreneurial spirit, we spotted an untapped opportunity in data management and analytics for and about energy efficient, healthy buildings. With an idea to automate the cumbersome workflows and use the vast pools of data on energy and construction worldwide, we assembled a team of brilliant scientists and programmers to bring cutting-edge technology to life.

Our presence now extends to multiple countries and markets. As we continue to thrive in the ever-evolving environmental and commercial landscape, we remain dedicated to reinvesting heavily in Research and Development. This unwavering commitment allows us to deliver the finest PropTech solutions to the market.

At the heart of our mission lies a commitment to assist businesses measure, report, and improve their ESG performance, actively contributing to the global transition to a zero-carbon future. Despite our remarkable growth, we have held onto our entrepreneurial spirit and familial roots, albeit on a much larger scale.
