We Are Cobuilder


Who we are

Cobuilder is a privately-owned international business with more than 120 employees. The company is headquartered in Oslo and has offices in Bulgaria, Belgium and France. We also have representation in Italy thorough our partner Harpaceas.

The company is a major driver for digitalization in the construction industry and is a strategic contributor to ISO, buildingSMART, CEN and CENELEC.

Vision and mission

Our vision is to create a better built environment for the people and for the planet.

A better built environment means buildings and infrastructure that are more sustainable, carbon neutral, efficient and safe. This is only feasible if the construction value chain is enabled with better data management throughout the built asset lifecycle.

At Cobuilder, we implement current and future industry standards for data management in our pursuit of this vision. This is captured within our company mission: Connecting construction to its digital tomorrow.

Our values


We analyse, we collect evidence and we showcase benefits that a whole industry can get advantage of.
We do not try to become ‘the standard’. We follow standards.


We stand for the whole industry, we help actors help each other.
Our central focus is on aiding collaboration between groups.


We take the liberty to dream big and focus on what might seem too far-sighted.
We take the risk of being ahead of our time.
