AI cost control for mid-market contractors. Pentabeam catches BoQ gaps, invoice errors, and untracked change orders before they reach your margin.
Pentabeam AI closes the gap between what you quoted and what you paid.
Pentabeam AI is a cost control platform built for mid-market EU contractors: the firms running multiple sites on Excel, chasing change orders by email, and discovering billing errors only when the books close. It replaces the manual reconciliation workflow across BoQ management, subcontractor invoicing, and cost forecasting with a single AI-assisted workspace. You see where every euro is going before it is gone.
Almost right isn't good enough when margins run at 5.5%. Here is the workflow Pentabeam replaces — and what happens instead.

Every number is sourced from published industry research: McKinsey, Deloitte, KPMG, GIRI, ARCADIS, HKA. This is the problem Pentabeam is built to solve. Hover any metric for the full source.
AI handles the checking. Your team makes the decisions.
Pentabeam replaces the Excel-and-email workflow that still runs most mid-market contracting. Each module fixes one specific failure mode, and all four read from the same place: your drawings, contracts, and email threads.

Pilots start with your own AI model trained on your past projects and a first invoice check within 30 days.

Each customer gets a dedicated AI model trained on their own historical projects. The model learns your cost structure, your trade rates, and your typical scope. It gets sharper with every project completed. The longer you use Pentabeam, the harder it is to leave.
No black-box answers. Every flag traces back to its source: the exact contract clause, BoQ line, or email thread that triggered it. When you dispute an invoice, you dispute it with evidence.
Built in the EU. Fully compliant with GDPR and the EU AI Act. Your project data never trains models for other customers. It stays yours, under contract.
Procore stores your paperwork. Pentabeam checks it. The market-leading platforms are strong at document storage and workflow, but none of them was built to check what a square metre actually costs you.

Every project you put through Pentabeam teaches it your rates, your wording and your subcontractors, so the next check is sharper than the last. Procore never learns what a square metre costs you to build.
Pentabeam reads the files you already produce: the priced bill of quantities, the subcontractor invoices, the emails. Nobody has to move onto a new platform first, and nobody has to learn a new way of working.
Pricing is matched to your company size and active site count. No per-user charges, no usage surprises, no variable components. One flat annual fee, single-line budget approval.
Four tiers cover everything from a handful of sites up to €150M+ groups. Pick the band that matches your revenue and that's the price.

One of us was running construction sites, the other was selling software. Pentabeam is built full time by the two of us, in Ljubljana. You will be talking to a founder from the first call onwards.
