The founder
Matthias, founder and lead developer.
Behind every project is Matthias, founder of Mazy 9 Studio and lead developer. You talk directly to the person who designs and codes your solution, from the first call to launch.
Why Mazy 9 Studio
Put your energy where it matters.
With artificial intelligence, building a website or an app has never been more accessible. Tools keep multiplying and promise to do everything in a few clicks.
But a tool doesn’t know what your project needs. You have to choose the right features, build a clear journey for your visitors and know what needs doing now and what can wait. Those decisions remain human. Learning to make them, while mastering the tools at the same time, takes time. Time you don’t spend on your business.
That’s why I created Mazy 9 Studio. I designed it for entrepreneurs, associations and project owners who want to move forward without becoming developers.
I take care of everything technical. I scope your project with you, design it, then build it, using AI where it genuinely saves time. After launch, I keep improving it with you. You stay in charge of the decisions, without having to manage the tools.
You stay focused on what keeps your project alive: your clients, your beneficiaries, your business.
