Each module stands on its own — and plays together with the others. One shared language for the entire tender lifecycle.
The tender lifecycle in Germany has three phases. Each loses time, clarity and money — because each phase today has its own tools, formats and mental models.
auftragr surfaces the right tenders. Not all of them. The right ones. Sources: TED, Bund.de, DTVP, Bayern and NRW — consolidated, filtered, matched against your company profile.
kalkulr evaluates the tender from five perspectives: executive summary, bid/no-bid, risks, clarification questions, claims potential. GAEB-native, VOB-aware.
zuschlagr structures bid evaluation for contracting authorities. Four stages. Four-eyes principle. Audit-proof procurement record. Humans confirm every AI suggestion.
Three products, one philosophy: AI structures the material. The decision stays with the human. That is not a compromise — that is the design.
BlackSwanAI supports your team in analyzing tenders in a structured way and preparing better-informed decisions.
Instead of taking work off your hands, we give you tools for clear thinking.
We look at tenders from different angles – similar to how experienced teams already think, but usually under time pressure and only in their heads.
Complex tender documents are clearly organized and sorted by relevant aspects.
Potential risks, assumptions, and open questions are explicitly highlighted.
With a structured information base, you can better prepare decisions about participation – the final decision remains with you.
The goal is to shift focus from document searching to decision-relevant content – freeing up time for strategic evaluation.
