Do your applications deserve better support?

Our application maintenance agency takes over, monitors, and scales your web, mobile, and AI applications when day-to-day management becomes unmanageable, without any service interruption.

Your apps crash in production

Recurring bugs, 500 errors, mobile crashes, unresolved incidents, blocked users. Your teams spend their time putting out fires instead of building.

Security updates are delayed

Unpatched CVEs, obsolete dependencies, outdated iOS/Android versions, abandoned frameworks: your applications are accumulating risks and verging on non-compliance.

New features drag on for months

Every minor improvement takes weeks to deliver, on the web as well as on mobile. Your business teams grow impatient and users leave for the competition.

Nobody is monitoring production

No serious monitoring, no proactive alerts: you discover incidents when your clients call you or when your app is downranked in the stores.

Your provider has disappeared

Abandoned code, non-existent documentation, no point of contact left. You are looking for a team capable of taking over the application without starting from scratch.

Technical debt is piling up

The longer you wait, the more expensive every modification becomes. At this rate, your applications will be unmanageable in 12 months.

Frequently asked questions about application maintenance

How much does a custom TMA contract cost ?

The price of a custom TMA contract depends on the scope (web, mobile, Al, or combined), the criticality of your application, and the desired SLA level.
An application maintenance package generally starts around €1,500 excl. tax/month for a small application, and can exceed €10,000 excl. tax/month for critical IT systems with 24/7 on-call support.
Our application maintenance agency provides a precise quote after a free audit.

Do you also maintain mobile applications ?

Yes. We support iOS and Android applications, whether they are native (Swift, Kotlin) or cross-platform (React Native, Flutter). This includes tracking store submissions, compatibility with new OS versions, crash tracking via Crashlytics or Sentry, and fast-tracked hotfixes in the event of a blocking incident.

What is the difference between corrective and preventive maintenance ?

Corrective maintenance takes place after an incident: bug, crash, regression.
Preventive maintenance acts beforehand: security patches, dependency updates, technical debt refactoring. Both are complementary: preventive reduces the need for corrective.

Can you take over an application developed by another provider ?

Yes, this accounts for about 40% of our application maintenance activity. We start with a technical audit (code quality, debt, security, infrastructure), then we propose a takeover plan in 3 phases: transition, stabilization, optimization. The takeover is done without any service interruption.

What monitoring tools do you use ?

We adapt to your existing stack. If nothing is in place, we generally recommend Datadog or Grafana for application observability, Sentry for web, Crashlytics for mobile, and PagerDuty for on-call management. The goal: to detect incidents before your users do.

Is there a minimum duration commitment for the TMA contract?

No, our custom TMA contracts do not require long-term commitments. You can cancel with a 3-month notice. This flexibility is intentional: if we do our job well, you won’t want to leave.
