Cosuno

Cosuno is a software-as-a-service platform for construction procurement. Its Cosuno Marketplace lets tendering companies publish bid packages and lets contractors search and bid on them. The site also lists Cosuno AI and a Subcontractor-Directory as features.

The website names general contractors, project developers, architects and subcontractors as its customer groups. It states that the goal is more bids per tender, less time in the procurement process and better award margins. The website does not describe its pricing or revenue model.

Cosuno was founded in 2019 by Christoph Berner, Fritz Cramer and Maximilian Seifert. The careers page lists 100+ employees and the legal entity Cosuno Ventures GmbH. Open roles are based in Berlin, on-site, hybrid or remote, across tech, sales, marketing and business functions.

Product: Online marketplace and SaaS platform for publishing and bidding on construction tenders, with Cosuno AI and a subcontractor directory.
