Cosuno

About

Cosuno began its journey in 2019 with a clear and ambitious mission: to digitize one of the world's oldest and most vital industries—construction. Founded by Christoph Berner, Fritz Cramer, and Maximilian Seifert in Berlin, the company recognized that while other sectors were rapidly evolving through technology, the construction industry was still heavily reliant on manual processes, opaque procurement methods, and endless spreadsheets. They saw an opportunity to bring transparency and efficiency to a sector that accounts for a significant portion of the global economy. What started as a vision to streamline the complex tendering process has grown into a leading SaaS platform that empowers general contractors, architects, and developers to manage their procurement and subcontractor networks with unprecedented efficiency. By leveraging state-of-the-art technology, including artificial intelligence, Cosuno automates the tedious tasks of sending inquiries, comparing bids, and managing documentation, allowing professionals to focus on building rather than administration. Today, Cosuno serves as a critical digital bridge, connecting thousands of construction professionals and ensuring that projects are built on a foundation of transparency and data-driven decision-making. With strong backing from top-tier investors like Avenir Growth, Spark Capital, and Cherry Ventures, the company continues to expand its reach across Europe, proving that even the most traditional industries can be transformed through innovation and a user-centric approach.
