Website and app takeover and maintenance

Your website or app is still running, but nobody looks after it anymore. We take over what others left behind, get it back on its feet, and then maintain it.

5 days

to bring a 2014 business application up to date, once the tests were in place.

Monitored

tested backups, uptime and automated tasks watched over, to catch the failures that don't show.

Your accounts

hosting, domain name, developer accounts: we start by recovering what belongs to you, even when nobody knows where they are.

Typical situations

A website nobody maintains is a ticking clock.

The agency has closed or the provider no longer answers. The website works, but nobody looks after it anymore. The situations we come across:

  • Access has been lost. Hosting, domain name, Google account, store developer accounts. A hosting invoice arrives every year, and nobody is quite sure where from.
  • The software "still works", but it hasn't been updated in years. It piles up known vulnerabilities and components nobody maintains anymore, without anything showing.
  • The failures are silent. Messages from the contact form land in spam, an automatic reminder no longer goes out, a nightly task hasn't run for days. No error is displayed, and you notice weeks later.
  • The mobile app risks being removed from the stores, because Google and Apple changed their requirements and nobody kept up.

What we do

We take over what exists, get it back on its feet, then we maintain it.

Takeover

We recover access, take stock of what exists, secure and update it, then document what we found so nobody has to do this work again. Websites, web applications and mobile apps.

Maintenance

A contract covering security updates, tested backups, uptime monitoring, fixes and small improvements. Hosting can be added as an option.

We don't criticize the previous provider's work: we don't know the constraints they had.

How we work

The foundations first, then the improvements.

01

Recover access and take stock

This is often the longest step.

02

Back up and test before changing anything

A verified backup, then tests that describe the current behavior.

03

Secure and update

The site's technical foundations, components nobody maintains any more, known vulnerabilities.

04

Then improve

Improvements come once the foundations are back in shape.

05

Maintain over time

With a contact person who knows your website or app, and whom you can call.

Why us

When something goes wrong, you talk to someone who knows your app, even in August.

We are a technical team based in French-speaking Switzerland. We've been doing this since 2012, across more than 320 projects.

We maintain software we built ourselves, and other software we took over, including two websites for Lausanne companies this year.

A few examples

Pixelmedics

A management platform for medical practices, which we have been developing and maintaining since 2023. In August 2026, a practice reported that patients no longer received their reminder text message when an appointment was moved. The fix was in place three days later, with a test guaranteeing that no message is sent twice, deployed at a single practice first, then at the others.

Educom

A business application from 2014 that was still running on its original technical foundations. Brought up to date in five working days, after setting up end-to-end tests. We also replaced seven abandoned components, closed several high-severity vulnerabilities, and stopped a duplicate server process that had been running for years without receiving a single request.

CSC Costruzioni

The energy consumption display runs continuously on building screens in Orbe, with an automatic restart after a power cut.

It all starts with a conversation.

Before the first screen, there's a conversation: what you want to do, for whom, and why. Let's take the time to talk about it.

First conversation free and with no commitment.

Frequently asked questions

How much does website maintenance cost?

It depends on what runs behind it: a showcase website on a common CMS doesn't need the same care as an application with user accounts and payments. The contract sets what is included; anything else is estimated before it's done.

What can we do if our web provider has disappeared and we no longer have access?

In most cases, everything can be recovered. The domain name, hosting and accounts can be reclaimed from the providers, with the right supporting documents. We help you through these steps, then we take stock.

Can you take over an application built by another agency?

Yes, whether it's a web application, business software or a mobile app. We always start by taking stock, and we tell you whether the takeover is worth it or whether it's better to start again on a fresh base.

How long does it take to take over a website or an app?

Taking stock takes as long as it takes to recover access, and it's often the longest step. To give a real-world idea: bringing a 2014 business application up to date took us five working days, once the tests were in place.

What does a maintenance contract include?

Security updates, backups and restore tests, uptime monitoring, fixes and a volume of small improvements. We also monitor automated tasks, to catch the failures that don't show. Hosting can be added as an option.
