Legacy
Replatforming of aging applications
The tool nobody dares touch anymore, rebuilt functionally identical.
Custom business applications · SMEs & mid-caps
An oversized SaaS you barely use?
A legacy application nobody dares touch anymore?
A need too specific for anything on the market?
A custom tool you dream of, but that no software-services-firm quote could ever make worthwhile?
That’s what we’re here for.
Your custom business applications, delivered in days.
What we deliver
- Business and technical experts who design your custom solution.
- Your business applications integrated with your IT, delivered in days, not months.
- All powered by the Factory, our AI-driven software production line.
- A result that is measured: your KPIs met at 90 days.
What we build
Your business applications, delivered in days. Not months.
SaaS
Exit from underused SaaS
The exact sub-scope you use, and it belongs to you. No more software rent: you reinvest the savings where they matter.
Operations
Operations cockpits & automation
Your data made visible, without touching your systems.
Custom-built, fixed price. Integrated with your systems, delivered in days.
Free 60-min diagnostic → The Factory Your vendors have Claude or Codex too.
Your vendors have Claude or Codex too.
They don’t have the factory.
Coding fast with AI is a commodity. What is not: a full engineering line working in relay, every link checked by the next. Quality no longer depends on who holds the keyboard. And the deliverable is deterministic: checked, verified, reproducible. LLM hallucinations stay inside the factory; they never reach your application.

On delivery day: proof that it runs
The machine launches your real application, executes it, and certifies it works.
The end of "delivered but broken".
At 90 days: proof that it serves
Hours saved, adoption, errors eliminated: signed on day one, measured on day ninety.
The end of "it works but nobody uses it".
A factory under human control: our experts validate every milestone and sign every delivery. The machine produces. Humans answer for everything.
The difference The classic model sells time.
The classic model sells time.
We sell a measured result.
| The classic model | The IA-PROS model | |
|---|---|---|
| You buy | Man-days | A result, a fixed price |
| The starting point | "Let’s add some AI" | We tackle the processes that cost you most, the most inefficient ones |
| The deliverable | Code, a report | A solution interfaced with your IT, used by your teams |
| "Done!" means | It shipped | The solution proved it runs, and your KPIs confirm it at 90 days |
| Oversight | For one day of development, nearly two billed: QA, project management, meetings, multiple contacts | QA, code review and documentation are deliverables of the factory, not a multiplier on the number of development days. Human oversight remains, on days, not months |
| The invoice | Time and materials | Fixed price: one scope, one number |
| Maintenance | A team billed, often idle, to "maintain knowledge" | We only bill interventions, neither availability nor maintaining the skill |
We don’t sell an application. We sell the result it produces.
The offer
One focused scope. Immediate impact.
No dependency on your global AI strategy, and nothing on its critical path: we pick one operational process, transform it fast and well, and let adoption and ROI make the case for going further.
What does this process cost you today?
What does inaction cost you?
Three fields. Thirty seconds. The real annual cost of your manual process.
€75,000 per year, in silence
- STEP 1
The Diagnostic
A senior expert. Your most costly process. A first estimate of the cost of inaction. And a straight answer: if AI is not your subject today, we tell you.
- STEP 1.5
The live demo
We don’t ask you to believe us. We show you the Factory running, on a case that looks like yours, live.
- STEP 2
The Blueprint
A one-day framing session: we clarify the need, spot the systems to connect, sketch the roadmap, price the project, and lay out a first mockup. Instrumented by our AI: you experience our method before buying the project.
Nothing actionable in the report? Your cost is €0.
- STEP 3
Your application
Replatforming · SaaS exit · Operations cockpit. The application in days, the Proof of Run at delivery, your KPIs at 90 days.
Ownership & freedom
The source code, the intellectual property, the documentation belong to you.
Source code, application, documentation, project knowledge base: all yours, delivered to your repository as we go. Standard, clean, documented code. You own it, and you are autonomous.
Maintenance & evolutions
- You take it in-house. Standard code your team can maintain. And if they want more firepower: Factory access for evolutions, your team at the controls of our line.
- You hand it over. To your usual IT partner, full handover guaranteed.
- You continue with us. The Factory never forgets your project, picks it up months later with its full context, and delivers without delay. No retainer, no on-call billing: only interventions are invoiced.
"You pay for interventions.
Memory and availability are never billed."
It’s precisely because you can leave that you can trust us.
The team
What doesn’t get coded.
IA-PROS is first of all an ultra-senior team, at the level of software-services-firm leadership: dual business and technical expertise, a sense of the operational, and the teaching ability to bring your teams on board and support you through gradual change management.
Around them, integrators in France and nearshore, French- and English-speaking, who connect your application to your systems and anchor it in your usage. Senior oversight, a single point of contact. This deliberate team model is what puts excellence at SME prices.
Proof first
A project is done when your teams use it and the result is measured.
Operations first
We absorb your business and your need before proposing a solution or a technology.
Honesty
We don’t oversell. If a project cannot be delivered by our platform, we tell you and point you to the right alternatives.
Human scale
Few clients at a time. Real quality of attention.
In 90 days, you have proof.
Not a promise.
IA-PROS · The AI that proves what it delivers.
60 minutes, free, no commitment. We identify with you the process that costs you most, and we tell you honestly whether we can transform it.
