What Ibau GmbH does

Ibau GmbH is a privately held German limited liability company founded in 1957 and headquartered in Münster, with 251–500 employees. It operates as a B2B information service for public tenders and commercial construction projects in Germany, consolidating fragmented procurement data into searchable databases under the sub-brands ibau Xplorer (the flagship portal for public tenders and private/commercial construction projects) and InfoBau Xplorer (a specialized platform for civil engineering, or Tiefbau, tenders). Each day, a team of 145 professional researchers supported by AI tooling monitors more than 50,000 contracting authorities (Vergabestellen) and processes over 450,000 annual tender announcements spanning construction, services, supplies, engineering, and architecture.

The core technology stack is a cloud-based tender and project database that combines AI-driven matching with human curation, and includes direct access to Leistungsverzeichnisse (bills of quantities) via the LV-Finder, automated tender alerts, project-phase tracking, and a company directory of more than 90,000 contacts (planners, investors, builders, municipalities). Supporting modules extend the platform into lead generation ("Top Potenziale"), bid result analytics ("Submissionsergebnisse"), sales automation, and a two-sided publishing service that lets project owners broadcast projects to the bidder network.

Ibau monetizes through subscription access to the ibau Xplorer and InfoBau Xplorer portals and through fee-based professional services, including the DialogManufaktur (outsourced customer acquisition and appointment scheduling) and the ibau Akademie (training and education). Go-to-market mixes self-serve product-led growth on the portals with a direct enterprise sales motion supported by request-for-presentation CTAs ("kostenlose Präsentation anfordern"), targeted at construction firms, service providers, suppliers, engineers, architects, and public-sector entities across all 16 German federal states, with a stated European partner network for adjacent coverage.

Direct peers

• Cosinex GmbH: Cosinex provides e-procurement and tender management software for German public-sector contracting authorities and bidders, overlapping with ibau's tender aggregation and specification (Leistungsverzeichnisse) access business.
• Subreport Verlag: Subreport is a long-standing German publisher and information service focused on public tenders and procurement notices, directly competing with ibau Xplorer in the same German RFP/RFQ information market with a similar subscription model.
• Vortal: Vortal operates a European e-procurement platform connecting buyers and suppliers across multiple countries, directly comparable to ibau's Xplorer as a tender discovery and bidding portal with similar subscription-based access for suppliers.
• Healy Hudson GmbH: Healy Hudson is a German vendor of e-government and e-procurement solutions, including tendering platforms for municipalities and suppliers, competing with ibau in the German public procurement information and software space.

Broad incumbents

• DTVP (Deutsches Vergabeportal): DTVP is a major free, multi-awarding-authority e-procurement platform in Germany for public tenders, serving a similar customer base as ibau Xplorer but as an open portal rather than a paid subscription aggregator.
• evergabe.de / Service Bund: Evergabe.de is a free public-sector procurement portal in Germany, providing access to federal, state, and municipal tenders, positioning it as a free substitute for ibau's paid tender database.
• Onvia: Onvia is a North American provider of government contract intelligence and procurement leads, highly comparable to ibau Xplorer in business model (subscription tender intelligence) but serving a different geography.
• BidNet (New York State Industries for the Disabled via HGACBuy): BidNet aggregates government procurement opportunities across U.S. states and Canadian provinces, sharing ibau's model of curating and distributing public tenders to suppliers via a subscription aggregator.

Emerging players

• Mercateo (Unite Network): Mercateo/Unite operates a B2B procurement marketplace for indirect materials and supplies in Europe, adjacent to ibau's supplier-side use case (companies finding procurement opportunities), with overlap in the German-speaking market.

Regional players

• TED (Tenders Electronic Daily, EU Publications): TED is the official EU portal for public procurement notices above EU thresholds, providing the underlying public tender data that aggregators like ibau complement, with broader European scope but no curated commercial project data.
