Sharing and learning is becoming the driver of radical innovation

We go ahead and share ideas, develop projects together and inspire the construction industry. Join us and walk the path into the new world of open source tools and open data.

Together for an open, innovative construction industry

Open innovation has given rise to many of the software innovations that are transforming the real estate and construction industry — from the cloud, to big data, to simulation technologies. But all of these came from outside. To spur this kind of innovation within our industry, we first have to create the right environment for it.

Our goal is to break down barriers to collaboration — between stakeholders along the value chain and even within individual firms. We do this to enable the cross-pollination of ideas necessary to spark transformative solutions to shared problems.

Why is this important? Enabling all stakeholders to participate in digital processes and operate on common, open standards is key – otherwise, high quality data and automated processes will not be possible to achieve, even with the best internal solutions.

Open Source Foundations create a neutral ground for collaboration

By facilitating open collaboration across companies, the open source movement has proven to be a powerful innovation engine with a strong focus on common standards and open tools – the modern web as an example can not be imagined without these.

Therefore, the role model for the initiative are established open source foundations in the tech industry like the LINUX foundation, the APACHE foundation or the ECLIPSE foundation.

Growing slowly but surely

In the first phase, we focus on building infrastructure that is needed to make existing projects, communities and people visible.

Then, facilitating the launch of new communities and projects is high on our list. Hosting these on neutral ground and enabling reliability and accountability can be really relevant – as long as there is need. Don‘t hesitate and get in touch, we would love to hear your thoughts on this.

For now, let‘s make the most out of our marketplace, the knowledge hub and the training section!

We like disruptive innovation.

But we also believe in empowering people to improve everyday – not in theory, but in practise.


The os.c marketplace is THE place for you to find a lot of great stuff.

You will find open source solutions ready to be explored in detail.

You will find open collaboration possibilities, posted by peers that are willing to take action and move forward together.

And you will find heaps of talented people, ready to push the industry further. Step by step and never stopping.

Who is behind the initiative? is a non-profit organisation based in Zurich, Switzerland.

The initiative was launched by Maximilian Vomhof in 2022 - out of frustration with the current status quo of innovation in the construction industry and with a strong passion for open collaboration.

Today, a group of committed individuals makes sure it grows slowly but surely – always with a strong focus on delivering value to the community of software developers, digital doers and established organisations that seek to thrive.

We are open to anyone who wants to join or contribute – please don‘t hesitate to get in touch!
