Today

Right now, the bid lives in four places that can’t prove anything.

  • The bill of quantities in a spreadsheet on someone’s desktop.
  • Tender documents as email attachments — which version, nobody’s sure.
  • Partners coordinated over WhatsApp, phone calls, and trust.
  • The signature tier guessed, not computed — a wrong default voids the bid.

One room instead. Built together, gated before you submit — and you leave holding the record.

Where we stand

vs Forgent

They find the tender and fill the forms. We’re the live room your consortium builds the bid in — and the record you can prove.

vs Ediphi

They have the real-time JV room, on shared trust. We add provenance, a regulatory gate, and graded confidentiality — useful from a single desk.

Build the first provable bid with us.

We’re onboarding a handful of Polish and German construction firms as design partners. Bring a live tender; we’ll build the loop around it.

Questions

Do you submit the bid for us?+

No. We assemble, validate, and package; you sign and submit through the official portal. We ingest the receipt back — submission stays a human act.

Does the AI set our prices?+

Never. The AI proposes and overlays; every binding price is a human event, enforced at the database layer.

Where is our data?+

EU-pinned end to end — storage, compute, logs. Your confidential pricing never leaves EU infrastructure, and we don’t train models on your data.
