Our story

Cosuno was founded in 2019 by Christoph Berner, Fritz Cramer and Maximilian Seifert and combines digitization standards and latest technology with one of the most important industries in the world: the construction industry.

We understand the complexity, tedious, manual processes and traditional methods of bidding and awarding construction services. For many, the procurement process means a lack of holistic insights, lack of transparency in the process, and a lot of lost time. That’s why we developed our Software-as-a-Service solution, which is based on state-of-the-art technology and automation.

Cosuno makes it easy for users to get more bids on your tenders, save time in the procurement process and optimise your award margins.

Our powerful team

We rely on creative talents who are not afraid to take on responsibility. Flat hierarchies, short communication channels at eye level, self-determined work and no bureaucracy – completely normal for us. We give room for continuous learning and the personal development of our employees.

In our international team, we work on a solution that significantly improves the everyday work of our customers.
