Develops software for the construction industry MoreLess
Cosuno GmbH is a German software company addressing the operational inefficiencies within the construction industry. The company was founded in 2019 by Christoph Berner, Fritz Fried, and Maximilian Seifert. The founding team combines diverse expertise; Christoph Berner has a background in business and previously worked at the Boston Consulting Group, Fritz Fried brings experience from the construction sector, and Maximilian Seifert has a technical background in software engineering. This blend of industry knowledge, strategic consulting, and technological capability underpins the company's approach to solving entrenched problems in construction management.
The firm has developed a Software-as-a-Service (SaaS) platform designed to streamline the procurement and subcontractor management processes for construction projects. It replaces traditional, fragmented workflows that rely on email, phone calls, and spreadsheets with a centralized digital solution. The platform targets general contractors and real estate developers, enabling them to manage the entire lifecycle from tendering and awarding contracts to invoicing and payment. Cosuno generates revenue through a subscription-based model for its software.
A core feature of the platform is its extensive network of subcontractors across Europe, which currently stands at over 250,000. This network allows clients to find and engage qualified partners efficiently. The software incorporates data-driven tools and an artificial intelligence component to assist with price comparisons and improve subcontractor capacity utilization. By digitizing these procurement workflows, Cosuno reports significant efficiency gains for its clients, including a claimed 60% reduction in time spent on these tasks and an average increase in profit margins of 18%. Since its market launch, the platform has processed a construction volume exceeding several billion dollars. The company has successfully raised significant venture capital to fuel its product development and international expansion plans, primarily focusing on the European market.
