About 123onsite

We develop software with passion – we can’t do otherwise

123erfasst: Baustellen-Apps für digitale Lösungen |

123onsites was born out of an idea by the company’s founder and construction contractor Jürgen Bruns, who had been looking for a mobile time tracking solution for his business for quite some time and couldn’t find a suitable one – so he developed it himself.

The ulterior motive was to develop a software for construction companies that would make work much easier. And this is done by having all the construction documentation directly incorporated into the accounting and project management. And all of this is captured with the tool that by now every construction worker has on his or her hands: the smartphone. Together with software developer Dominic Sander, Jürgen Bruns invented 123onsite, a smart and efficient solution. A few years later, the app has grown tremendously, and so has the company – with consistent growth averaging 60-80% annually, 123onsites has now become the market leader in mobile construction site management.

2018 marked the strategic acquisition of 123onsite.de GmbH by NEVARIS Bausoftware GmbH, the technology leader for digital processes in the construction industry. What started with two highly motivated experts has developed into a modern company with a Silicon Valley atmosphere located in northern Germany. This is where we develop our software with a great deal of passion for our work and in an agile, motivated team of meanwhile more than 20 colleagues. With heart and fun – for you!
