Docu Group

What Docu Group does

ibau GmbH, operating under the trade name ibau and sometimes referenced as Docu Group, is a Münster-headquartered German information-services company founded in 1957 that aggregates and disseminates public tenders, private construction projects, and procurement opportunities across all 16 German federal states. Its core platform, the ibau Xplorer, provides searchable access to over 450,000 announcements annually from more than 50,000 awarding authorities (Vergabestellen), supplemented by a specialized civil-engineering portal (InfoBau Xplorer), a construction-project database with project-phase information (Bauprojekte), direct access to detailed specification documents (Leistungsverzeichnisse), bid-results data (Submissionsergebnisse), a premium leads product (Top Potenziale), and a company directory (Firmenverzeichnis). The platform is powered by an AI-Enhanced Research Network that combines 145 in-house professional researchers with artificial intelligence to monitor the market daily, drawing on an exclusive network of over 90,000 planners, investors, clients, municipalities, and awarding authorities.

The company's revenue model combines recurring subscription access to its Xplorer platforms with professional-services revenue from its DialogManufaktur (sales support, new-customer acquisition, appointment scheduling, and bespoke research) and ibau Akademie (training, fresh-up sessions, and downloadable procurement-law resources). Go-to-market is sales-led, distributed through self-serve web portals for SMBs and individual buyers, alongside inside-sales phone support (toll-free 0800 line) and direct enterprise sales for larger accounts. ibau serves a horizontally segmented customer base spanning construction companies, building-materials manufacturers (e.g., Knauf Gips KG, FunderMax GmbH), public-sector contractors, trade and craft businesses, and engineering/architecture firms. The business is privately held as a GmbH with no disclosed parent company, investors, or M&A activity.

Operationally, ibau is mature and stable rather than hyper-growth: 67 years of continuous operation, Germany-only geographic footprint, no public funding events, and no disclosed acquisitions or leadership changes. Strategic momentum is incremental — broadened product surface (Sales Automation, Akademie), AI augmentation of research workflows, and a maintained European Partners Network — consistent with a profitable, subscription-anchored niche information-services firm rather than a venture-backed scale-up.

Direct peers

• Auftragsbörse (AB Service GmbH): Construction-specific tender search platform focused on German Handwerk and Baugewerbe. Closely comparable offering to ibau Ausschreibungen with a similar SMB/craft customer base.
• BauInfoConsult: German construction-industry research and market intelligence firm offering reports, databases, and lead-generation services. Comparable to ibau's research-and-intelligence offering, especially for building-materials manufacturers like Knauf and FunderMax.
• Heuer Dialog GmbH: Provider of construction-industry sales and marketing intelligence, including tender research and customer-acquisition services. Directly comparable to ibau DialogManufaktur on the professional services side.
• Vergabe24: Public-sector procurement portal serving German municipalities and awarding authorities. Competes head-on with ibau on public tender aggregation and distribution to bidders.
• subreport Verlag Schawe GmbH: German publisher of public-tender bulletins (Submissions-Anzeiger) serving Handwerk, trade, and small contractors. Closely comparable print-plus-digital tender distribution model to ibau's traditional core.
• cosinex / evergabe.de: Public online tender search service for German Vergabestellen announcements; provides comparable public-tender coverage to ibau's Ausschreibungen module.
• cosinex GmbH: German provider of electronic tendering (e-Vergabe) and supplier management software for public-sector procurement. Direct competitor to ibau's e-Ausschreibung positioning, especially with Vergabestellen and large contractors.

Regional players

• TenderNed: Dutch public eProcurement platform operated by the Ministry of Economic Affairs. Comparable public-tender intelligence model outside Germany, useful as a benchmark for ibau's potential European expansion.

Others

• Crunchbase / europa.eu TED: Official EU Tenders Electronic Daily portal providing free pan-EU public-procurement data. Functions as the open-data baseline against which ibau's value-added intelligence is benchmarked and priced.

Broad incumbents

• SAP Ariba (Discovery): Global enterprise procurement and sourcing platform that aggregates public/private tender opportunities at scale. Represents the broad-incumbent threat to ibau, particularly among larger enterprise customers with embedded procurement tooling.
