Patrick Penn


Originally a computer scientist and system integrator at CORPUS SIREO, Patrick Penn has been passionate about data and document management in the real estate industry for almost 20 years. Practical experience during his work, including as a consultant and developer with a focus on Microsoft SharePoint, has revealed the challenges that strategic data management faces in real estate companies. Paired with the findings from services provided around the construction and structuring of data rooms for purchases, inventory and transactions, the vision for docunite, a DMS specializing in the real estate industry, was formed. He has been the owner and managing director of docunite GmbH since 2017 and, together with his team, continuously pursues the goal of replacing data silos with integrations and innovative solutions and steadily increasing sustainability and efficiency in data management in the real estate industry.
