MVP live · made in MössingenKnow the price
Know the price
before the first
tradesperson arrives.
Bauplex builds you an AI bill of quantities with real market prices — before you request a single quote.
One mechanism, two winners
One mechanism. Both sides win.
Every Bauplex feature delivers a benefit to the property owner and the contractor at the same time.
Pay after sign-off
For Property Owners
Plan construction projects smartly — from concept to secure payment.
1
Describe your project
Describe your construction project or upload an existing quote. Our AI instantly creates a detailed bill of quantities with market prices.
- Free text or PDF upload — AI automatically identifies all trades and line items
- VOB-compliant service descriptions with regional market prices
2
Compare quotes
Qualified contractors price your project. You compare all quotes transparently in the price comparison.
- Only verified businesses with master craftsman certification, insolvency check, and reviews
- Price comparison with color coding: affordable, fair, or overpriced — at a glance
3
Build with full control
Commission directly, track progress in the site diary, and release milestones after acceptance.
- Site diary with photos, materials, and daily reports in real time
- Payment only after acceptance — transparent milestones for both parties
The story behind it
Why we built Bauplex
After over €60,000 in damages during my own renovation, it was clear: we need a platform that brings property owners and honest contractors together — with fair prices, transparency, and security for both sides. That's why we tested Bauplex on our own house project first. Patient Zero.
The best of both worlds
Bauplex isn't just contractor matching. Before you even request a quote, you already know what your project will cost and what it should include.
Full transparency before the first contractor
- AI bill of quantities with market prices — you know upfront what it will cost
- Price comparison shows at a glance who's pricing fairly and who's not
Secure payments for both sides
- Payment only after acceptance — per milestone, not upfront
- Every step documented: site diary, photos, and acceptance reports

Early feedback from our pilot phase. We label it honestly as such — no invented reviews.

Contractor„The AI pre-quote was 80% done when I received it. I just had to fine-tune instead of calculating from scratch.“
