About
Two developers in Strasbourg who write your software, host it and fix it.
Sanfytech is two developers in Strasbourg. We write your applications, we run them on our servers in France and we answer when something breaks. There is nobody between you and us.
01/Who we areTwo developers
Two developers, accountable for everything
There are two of us, and we write the code we deliver to you ourselves. Development is not subcontracted: the person who designs your application is the one you have on the phone, and the one who gets woken up when something breaks at night.
Cédric designs the applications and runs the hosting: architecture, security and day-to-day operations over the long term. Ayyoub shapes the business applications and their interfaces: careful code and screens that are easy to use every day.
The company is young: SANFYTECH SAS was registered on 15 July 2026. We do not inflate what has not yet been measured. The figures we publish are dated, and their method is written next to them, on the hosting and managed services pages.

02/What changesFour consequences
What changes when the developer is also the host
Writing an application, hosting it and looking after it often means three different providers. With us, it is the same two people. Here is what that changes for you.
Someone who already knows your project
When you call, you reach the people who built your application and who host it. You do not have to explain your project all over again each time.
You remain free to leave
The code written for you is yours, with its documentation, and you take it with you if you change provider.
Data hosted in France
Your data is on our servers, in France, and we back it up every night. A contract sets out who can access it.
An alert, and someone steps in
We continuously monitor the applications we host, and any outage is reported to us straight away. One of us steps in, including at night.
03/Our productsTwo products of our own
Two pieces of software that are ours, from the first line of code to the hosting
We do not only work to order. Two products are published by Sanfytech, written, hosted and maintained by us: it is the simplest proof that we know how to keep an application running over time.

Four stages, each one approved with you
This is how a project runs with us, whether it is a business application or a website.
- 01
Scoping
We start from your line of work, your constraints and your budget. The first conversation is free, and you receive a quote before we start.
- 02
Design
We draw the screens and describe how the tool will be organised, explaining our choices. You approve the whole thing before we move on to development.
- 03
Development and demonstrations
We move forward in small steps and show you the result each time. You see the tool take shape and you can ask for corrections along the way.
- 04
Go-live, hosting and support
Once live on our servers in France, your application is monitored and backed up, with someone on call if something breaks. We also carry out the updates.
The quote is written before we start; a change of scope along the way is covered by a priced amendment, never by a line that suddenly appears on the invoice.
05/Where we areStrasbourg, Alsace
In Strasbourg, and anywhere in France remotely
We work from Strasbourg, in Alsace. Meetings take place in person when it is useful, by video call otherwise, and we work with clients across France remotely, with regular check-ins.
