We develop and operate the project management software "flexxter" that construction companies can use to plan and collaborate on projects together. Nearly every company in the construction sector is working jointly with other companies on their projects. But the main challenge within this projects is the communication between all the projects' participants. That's why again and again information get lost, will not be noticed or misunderstood. And despite that fact no software exists that can handle the entire collaboration process from beginning to end in all its details. That was until now - Because we at flexxter make it possible to plan your own projects and communicate with all the projects' participants.
Our solution has been anounced as one of the TOP 10 Smart Construction Start-ups in 2020 and we are constantly expanding our business.

We are a highly skilled and experienced team of former consultants, developers and project managers which helps us develop great products! Every one of us is taking responsibility for their projects and so will you! Every opinion is heard and part of our decision making process.
