Win More Contracts – Without Expanding Your Team
Search in natural language across all relevant tender platforms. Our AI automatically analyzes tender documents and checks fit with your company and references – 66% faster than manual work.
Why Leading Construction and Engineering Firms Use Tender Zen
Tender Zen continuously searches public tenders across Germany and Europe (including below-threshold procedures). Never miss a relevant tender again.
From 6 hours to 2 hours per week for tender search and prequalification. Validated by our construction customers. Use the saved time for billable projects instead of admin work.
No more complex search criteria on different platforms. Simply describe what you're looking for in natural language – our AI finds all relevant tenders.
No more knockout criteria on page 48. Our AI analyzes all tender documents in multiple iterations and self-verifies to ensure ALL requirements are extracted.
Instead of reading hundreds of pages manually, you get structured, clear analyses. This lets you review more tenders and submit qualified proposals.
Continuous monitoring alerts you immediately when relevant tenders are published. Be first to respond.
