Your AI tool,
validated by humans.

Built an internal tool with AI? Your team shipping solutions without a technical framework? Before any deployment, our pairs of senior developers read your code and identify exactly what could cost you.

Your context

AI code moves fast.
Until the day it doesn't.

Nearly half of all code produced today is written with the help of AI. Non-technical profiles build their own tools without going through a dev team. Developers ship faster than ever - sometimes faster than their verification processes allow. The movement is real, the gains are concrete, and no one is going back. What the demos don't show is what happens next.

These numbers don't mean AI writes bad code. They show the scale of decisions being made without supervision - never checked before going into production.

This isn't an AI problem. It's a supervision problem. ValidAI exists precisely to bridge the gap between a tool that runs and a tool that holds up.

The agency

Developers who work with AI.
Not for it.

We know AI's blind spots because we encounter them in production.

We're not an AI that generates reports. We're a development agency with years of experience in production, security and architecture, who have learned to work with AI tools by understanding precisely their limitations.

When we audit your code, we actually read it. We annotate it, analyse it, understand it. And if you have an incident six months from now, we can find exactly why.

How it works

Two steps.
An actionable roadmap on the way out.

01
From €3,500
Full audit by humans
A pair of senior developers goes through your code in detail. 18 scored and justified criteria, full report with code extracts, prioritised remediation roadmap. Delivered in under 2 weeks.
02
On quote · Optional
Remediation support
We take care of the identified fixes: security, refactoring, test implementation. Directly aligned with the delivered roadmap, without having to re-explain everything.
What AI doesn't tell you

AI makes choices.
You don't see them.

These tools do what you ask - but they also make decisions where you asked for nothing. Without technical expertise to validate those choices, they stay invisible until they become costly.

01
Security
The AI implemented authentication - but which kind, under what assumptions, for what risk level? Without expert review, those decisions remain opaque.
02
GDPR
What data is collected, for how long, in which logs? The AI made default choices. Compliant or not - you can't know without reading the code.
03
Architecture
The code structure reflects the AI's assumptions about your context - not necessarily yours. Those choices shape everything that comes after.
04
Scalability
A prototype that works for 5 users is not a product that holds at 500. Performance trade-offs were made implicitly, without knowing your constraints.
05
Maintainability
When a team takes over the code, or something breaks, the cost depends on decisions made from day one. The AI didn't have your roadmap in mind.

Process

Five steps.
Your teams stay focused.

From the scoping call to the delivered report, the process is designed to demand as little as possible from your teams.

02
NDA & Quote
Quote + T&Cs. Signature + 50% deposit. Code access via private Git repository. Systematic NDA.
03
Audit
A pair of senior developers goes through your code in detail: 18-criteria analysis grid, observations with code extracts, report writing.
04
Delivery
Word + PDF report. Debriefing session if included. 50% balance on receipt.
05
Optional follow-up
Remediation handled by MV Studio, or a 3-month follow-up session to review correction progress (+€500). Your choice, at your own pace.

Frequently asked questions

Everything you want
to know before getting started.

Answers to the most common questions about AI code auditing, our method and how we work.

An AI code audit is a structured analysis of software built with AI tools such as Cursor, GitHub Copilot, ChatGPT or Claude Code. ValidAI evaluates the code across 18 criteria in 5 weighted areas: security, GDPR, architecture, scalability and maintainability. Each criterion is scored and justified with a concrete example from the code. The goal is to identify real risks before production deployment or handover to a technical team.
AI tools do what you ask. They also make implicit decisions about security, GDPR compliance, architecture and load management. Without technical expertise to validate those choices, they stay invisible until they become costly. The ValidAI audit makes them readable before you go to production.
AI code isn't risky because AI lacks technical skill - it's risky because it makes decisions on your behalf without flagging them: which authentication strategy, what data gets logged, which architecture to handle load, which shortcuts around duplication or unverified assumptions. These implicit choices stay invisible without an expert reading the code, whether they touch security (authentication, hardcoded secrets, input validation), GDPR (data collection, retention, logs), architecture (duplication, tight coupling, structure), scalability (unoptimized queries, no caching) or maintainability (no tests, documentation, usable git history).
The ValidAI code audit is fixed-price, starting from €3,500. The exact rate is set during the free 30-minute scoping call, based on project size, complexity and your context. A fixed quote is sent within 24 hours. Remediation (fixing identified issues) is quoted separately, based directly on the delivered roadmap.
Delivery is under 2 weeks in all cases, from receipt of repository access. If your project has a critical deadline, flag it during the scoping call. We adapt the schedule where possible.
Yes, a confidentiality agreement (NDA) is signed systematically before any access to the code repository. Access is exclusively via a securely shared private Git repository. No source code is transmitted by email or any other unsecured channel. The NDA is signed after the quote is accepted and a 50% deposit is paid. Confidentiality is absolute and contractually guaranteed.
The full audit is an in-depth analysis by a pair of senior developers: 18 scored and justified criteria with code extracts, Word + PDF report, prioritised remediation roadmap and debriefing session included. From €3,500, rate defined during the scoping call. Remediation support is an optional step following the audit: MV Studio takes care of fixing the identified issues (security, refactoring, testing). Quote based directly on the delivered roadmap.
The ValidAI report includes: an overall score out of 100 broken down across 5 weighted areas, detailed scoring of 18 individual criteria with justification and concrete code extracts, a risk summary ranked by criticality level (Critical / Major / Minor), prioritised and actionable recommendations, a remediation roadmap with effort estimates per action. The report is delivered in Word + PDF format, accompanied by an oral debriefing session.
Yes, confidentiality is an absolute priority. An NDA is signed before any access. Code is shared exclusively via private Git repository. No copy is retained after the report is delivered. ValidAI is a service of MV Studio, a Belgian company subject to GDPR. Data processing is strictly limited to carrying out the commissioned audit, and no external subcontractor has access to your code.
Yes. Optionally after the audit, MV Studio can handle the remediation: fixing identified security vulnerabilities, architectural refactoring, automated test implementation. This is quoted separately based directly on the delivered roadmap. You know exactly what will be done and for how much. A 3-month follow-up session is also available at €500 to review the progress of corrections carried out by your team.
