Cosuno

Market position

Positioned as a tendering and procurement platform for the DACH construction market, with the company describing its network as the largest construction network in DACH. TechCrunch cites the U.S. company Built as a similar model, with co-CEO Fritz Cramer arguing Cosuno offers more features because it also covers planning and a subcontractor marketplace ahead of invoicing and payment. Coverage frames construction as one of the least digitized large industries.

Cited differentiators are the size of its contractor network (80,000 in 2022 materials, 180,000+ by mid-2023, 250,000+ per the current site), coverage of the full pre-construction cycle from planning and tendering through award, contracting, invoicing and payment, AI-based price forecasting and bidder matching, and integrations with established construction ERP/AVA systems. Company-reported outcome claims include roughly 50-60% time savings on manual processes, higher bid response rates, and increases in award profit (5.7% per the current site, 25% per 2023 materials) and average profit margins (18% per 2022 materials).

Technology

Cloud-based SaaS with an interface for creating tenders, dispatching documents, collecting digital bids and comparing prices automatically. Stated technical elements include a GAEB interface for importing bills of quantities, unlimited document sharing with automatic change notifications, a historical price database, and integrations with SAP, RIB iTWO, Nevaris Build and BRZ. AI components described by the company include a price assistant trained on tender data that uses semantic text matching for comparable prices, an AI agent that checks tenders and specifications for errors and risk factors, and AI-powered matching of suitable bidders.

Go-to-market

Direct enterprise sales supported by demo bookings and call-back requests on the website (business email required), customer testimonials from procurement leaders at large construction and retail-development firms, a content marketing magazine/blog on construction industry topics, and a public marketplace where buyers publish bid packages and contractors register and save searches to receive tender notifications. Secondary reporting describes an early lead-user approach that onboarded large contractors.

General contractors, property developers, construction companies, architects and planners on the buying side, and subcontractors and trade/craft businesses on the bidding side. Named customers and reference users include ALDI SÜD, Haas Fertigbau GmbH, Freundlieb Bauunternehmung, hochplan GmbH & Co. KG, and, per secondary sources, SIGNA Bau and Eiffage Infra Bau.

Geography

Headquartered in Berlin, Germany, with an office in Berlin-Mitte as of 2022. Marketplace tenders listed on the site are located across Germany (including Darmstadt, Düsseldorf, Berlin, Munich, Nuremberg, Hamburg, Magdeburg, Bielefeld and Regensburg). The network is described as European with a DACH focus; after the 2022 Series B the company stated it planned to expand into additional European markets.

History

Founded in 2019 (one source states 2018) in Berlin. A $15 million Series A led by Spark Capital with Cherry Ventures was announced around May 2021; roughly six months later, in February 2022, the company raised a $30 million Series B led by Avenir Growth with Spark Capital and Cherry Ventures participating, reaching a stated $150 million valuation and about $45 million in total funding. At that point the company had 140 employees and reported more than $4 billion of construction volume processed since market launch. By July 2023 it reported over 180,000 qualified subcontractors; its current website cites more than 250,000 contractors and cumulative offer volume exceeding €100 billion, alongside AI-based pricing and tendering features.

Risks & controversies

No controversies or legal or regulatory issues are reported in the available sources. Data inconsistencies across sources should be noted: founding year is given as both 2019 and 2018; total funding as $45.0M and $45.2M; and one directory lists an implausible employee count of 10,000+ alongside a 140-employee figure reported elsewhere. Investor lists in one aggregator entry are extensive and appear unreliable relative to the named leads reported by primary press coverage. Performance figures (time savings, margin uplift, response rates) are company-stated and vary between 2022, 2023 and current versions of the site. Coverage also notes that construction is a slow technology adopter and hard to disrupt.
