Your system stable. Your business calm.
A mature system needs continuous technical care: bugs to fix, integrations to keep current, small requests that smooth the day-to-day. We handle that work, every day, without disruption.
Built for established businesses that rely on software.
Who's it for
- Established businessConsolidated operations where software is essential to the day-to-day.
- Years of operationPlatforms refined over time, holding business logic that can't be lost.
- Internal focus on the businessTeams dedicated to operations, without a dedicated development capacity.
- Long-term relationshipA continuous partnership, each side on its own ground, with fluid communication.
What you'll get
An engineering team accountable for your product, without hiring anyone.
- Zenite knowing your codebase by heart.
- Proactive maintenance and continuous monitoring.
- Bug fixes, hotfixes and ongoing evolution.
- A plan matched to your product and its stage.
The maturity of an established team, from day one.
Keeping software healthy for years is its own discipline. It asks for an engineering team that has done it before, a process that catches problems early, and someone genuinely accountable when something breaks.
AppX Care gives you exactly that, without building, training and managing a technical team internally.
- In place from day oneNo months of recruiting or ramp-up. The team is ready and productive from the first week.
- The same engineering teamThe people behind a decade of live products are the ones on your system, not a rotating support queue.
- One partner, fully accountableA single team owns the health of your system, so nothing falls between the cracks.
In eight years keeping digital products alive across five countries, we've learned that a mature platform asks for continuous technical work. It gains value when there is a technical team on the other side handling each point as it appears. AppX Care was built to be that team.
We keep your system running, and evolving.
Low-intensity technical work is the natural rhythm of a live platform. AppX Care answers it, with method and without disruption.
Bug fixes and hotfixes
Fast, careful resolution of the issues that surface in day-to-day operation.
Monitoring & response
Continuous detection and intervention within your contracted SLAs.

It knows your product
by heart.
Zenite is AppX's proprietary engine. It reads your whole codebase and rebuilds the knowledge that usually lives only in the heads of the people who built it: how the system fits together, and above all the business rules it runs on.
- 01
Reads the codebase
Every module, and how they depend on each other.
- 02
Maps the data models
The schema and the relationships inside it.
- 03
Extracts the business rules
The logic your product runs on, not just the code.
- 04
Generates a test suite
A safety net that guards every future change.
Most of what Zenite holds is the part nobody writes down: your business rules, the reasons your system behaves the way it does.
- Fixes that respect the rulesEvery change is checked against the logic your product actually runs on, so it never quietly breaks something that used to work.
- Knowledge kept in the openYour system's full picture lives in Zenite, in the open, not locked inside one person's head. The whole team works from the same map, every time.
- The whole system in viewZenite sees how a change ripples through the rest, so a small fix doesn't open a new problem elsewhere.
When something breaks, a team is already on it.
It starts the moment an issue appears, and runs through one continuous loop: detection, diagnosis, the team's own judgement, and a clean deploy.
An issue appears
A bug, a broken integration, a spike in load. This is where it starts.
We catch it
Monitoring opens an incident, often before your users notice.
Scope & fix
- 2.1Zenite scopes it
It reads the error against the live map of your system and proposes a fix built on your business rules. Knowing those rules is Zenite's real strength.
- 2.2The team signs off
They review that fix against the same rules, and only then does it move on to testing.
Validated by tests
Zenite's test suite runs against the fix before deploy.

Frequently asked questions.
Is this solution ideal for me?
It fits teams with a product already live and users depending on it, who would rather not build and manage an in-house technical team just to keep it healthy and moving.
Do you take on code you did not write?
Yes, that is the most common case. The onboarding starts there: code ingestion, system analysis and mapping, technical documentation, and a review with you before we begin.
What is Zenite?
It is AppX's proprietary engine. It reads your product's entire codebase and rebuilds the knowledge that normally lives only in the heads of the people who built it: how the system fits together and, above all, the business rules it rests on.
What is the difference between the three plans?
The level of support and the capacity to evolve. The team and the process are the same across all of them. We help you pick the one that fits in a short discovery session.
How much does it cost?
Plans are quoted case by case, because they depend on the size and complexity of the product and the stage it is at. In a short session we understand what you have and put forward the plan that fits.
A short, no-commitment discovery session.
We look at your product as it stands today, map the current stage and recommend the plan that fits. You leave with clarity on scope, SLA and timeline. No pressure, no upsell.
