Which tender platforms for public procurement are searched?

Tender Zen searches 150+ public tender platforms in Germany – including major federal state platforms, federal platforms, and municipal platforms. For above-threshold procedures, we also search EU-wide platforms.

How quickly can I find tenders with Tender Zen?

You can set up your search profile with Tender Zen and find your first tenders in under 10 minutes. Our AI automatically creates the profile – via website import, from your documents, or from a short description.

Which industries and trades is Tender Zen suitable for?

Tender Zen currently supports construction-related services and IT services. This includes architecture and engineering firms, construction management, HOAI-regulated planning services (service phases 1–9), software development, IT consulting, and related services.

How much time does Tender Zen save on tender research?

With Tender Zen, construction firms save around 66% of the time spent on tender research – from an average of 6 hours to 2 hours per week, right from day one. After onboarding, savings increase to up to 89% (under 1 hour per week). Validated by LOUPZ GmbH in construction.

How does Tender Zen differ from DTAD, Vergabe24, and other portals?

Tender Zen is the only platform with an end-to-end AI workflow from search to proposal. Traditional portals offer keyword search on a single database. AI portals add semantic search. Only Tender Zen combines AI search across 150+ platforms with automatic document analysis, reference matching, and proposal generation.

Yes. Tender Zen offers an interface for integrating tender data into your existing CRM or ERP. For Enterprise plans, we set up custom integrations.

Is my data stored in a GDPR-compliant way?

Your data is stored by Tender Zen in a GDPR-compliant way in European data centers and is used exclusively for your service – no sharing with third parties, no training of AI models with your company data. Optionally, we offer self-hosting on your own infrastructure.

How complex is setting up Tender Zen for my team?

Setting up Tender Zen takes under 10 minutes: register, create a search profile via website import or description – done. For Pro and Enterprise customers, we offer personal onboarding.

Is there a minimum contract term or commitment?

No, Tender Zen has no minimum contract term. With monthly billing you can cancel anytime; with annual billing you save two months and can decide flexibly after the year ends. The Pay-per-Use plan has no subscription at all – you buy credits that never expire.
