MAINFRAME Chantier
Win more tenders. Run every site.
The platform for construction and civil-engineering companies: AI that reads tender files and drafts your technical proposal, plus your equipment fleet, sites and field reports in one place.
- Public works & civil engineering
- Building contractors
- Design offices
- Inspection offices
01 / The problem
Tenders decide your revenue. They still eat your weeks.
Hundreds of pages per tender
Rules, contract clauses, specifications, price schedules: someone has to read it all to decide whether to bid, and find the clause that will cost you later.
The same proposal, rewritten
Every technical proposal starts from an old Word file, re-assembled by hand with references, staff and equipment.
Equipment and sites in spreadsheets
Which machine is where, what is due for inspection, what each site really costs: spread across files, phones and people.
02 / Tender agent
From tender file to go / no-go in minutes.
Drop the tender file. The agent reads every document, extracts what decides the bid, checks it against your equipment and certifications, and prepares the outline of your technical proposal. Your team decides.
- Deadline, required documents and scoring criteria, extracted
- Risky clauses flagged before you commit
- Checked against your own fleet, staff and certifications
- Read
- Extract
- Check
- Draft
03 / The platform
Tenders first. Then the rest of the company.
We build it module by module with our pilot companies, starting where it pays first.
- Building now
Tenders
Daily watch of public tenders for your trades and regions, AI analysis of tender files, go / no-go, technical proposal drafted from your references, deadlines and documents tracked.
- Next
Equipment & assets
Machines and vehicles, allocation per site, utilisation, maintenance and mandatory inspections, cost per hour charged to each site.
- Planned
Sites & progress billing
Budget against actual, progress invoices, subcontractors, holdbacks and change orders, site by site.
- Planned
Field reports
Daily site reports, photos, incidents, quality checks and handover reports from a phone, even offline.
04 / Why us
Built by people who have shipped this before.
Construction ERP experience
Our founder has already built an ERP for a civil-engineering technical inspection office: clients, projects and inspections.
Your data stays yours
Hosted in France (AWS Paris). Your prices and proposals never train an AI model.
Keeps your accounting software
We connect to the tools you already use for accounting and payroll instead of replacing them.
05 / Pilot programme
Build it with us.
We are looking for a few construction and civil-engineering companies to shape MAINFRAME Chantier with us.
What pilots get
- Early access to each module as it ships
- A real say in the roadmap
- A founding price, locked in
- A direct line to the people building it
What we ask
- About one hour of feedback a month
- A few real (or anonymised) tender files to test on
FAQ
When can we use it?
Pilot companies get each module as it is built, starting with tenders. We will tell you the dates when you apply.
Where is our data hosted?
In France, in the AWS Paris region. Your tender prices and proposals are never used to train AI models.
Do we have to change our accounting software?
No. MAINFRAME Chantier connects to the accounting and payroll tools you already use.
How much will it cost?
Pilots get a founding price, agreed with them and locked in. Public pricing comes later.
