For construction companies · October 2026
Dundir
Up to seventy percent of your project is procurement.
Dundir is designing a procurement solver and a jobsite gate for construction companies. Both are in development with design partners; nothing in this deck runs at a client yet.
The cost structure
Bought in, compared by hand.
The unit price gets optimised. That is rarely the biggest issue. Where is the material, when will it arrive, and is it certified?
Materials up to 70% of total project cost. Donyavi et al. 2024, in Hamppi 2025, p. 8 [EVID-001]
The problem
Office, gate and memory.
€8,354
Swing on one subcontractor’s total when a generative AI tool was given the same bids in a new session.

of staff see a 500 to 600 million euro Dutch infrastructure project through from start to finish, an interviewee says. Supplier knowledge leaves with them.

Procurement decisions Stage: research and design
Computing, not generating.
A language model writes an answer. An optimisation engine works one out.
Hard requirements are fixed first: certification, delivery date, budget ceiling, CO₂ limit. Price and reliability are weighed inside them, by weights you set. Same input, same answer, and the reasons written down at award.
The pilot
Ten weeks, starting from closed tenders.
No hardware and no ERP integration needed for the first result. Everything stays inside your network, under an NDA.
Where we stand
Stage, not product.
| Module | Stage |
|---|---|
| Procurement solver | research and design |
| Smart gate | lab prototype |
| Supplier record and contract memory | design |
What we have not proven yet. That the solver buys better than an experienced buyer. The literature supports the problem and the local design; the rest has to come from pilot data, and we do not have it yet.
What we are asking for
A pilot as a design partner.
