About Seicho
Growing, with care.
Seicho means “growth” in Japanese.
The founder
Hello, I’m Julien.
I founded Seicho on a simple conviction: even the most advanced technology is only worth something if it serves people, with clarity and care. For more than fifteen years, I have designed, built and run IT systems, from the most visible to the most critical.
What drives me above all is meeting people. Understanding a trade, listening to what holds it back, finding the right solution together: that is where everything begins. I love the rigour of engineering as much as the elegance of design, and I am convinced that a beautiful tool is, first and foremost, one that makes life easier.
I am still learning every day, and that is what makes this work so exciting.

成長
The name
Patient, solid growth.
Seicho means “growth” in Japanese. Growth like that of a tree: you prepare the ground, take care of every stage and build to last.
The name brings together two cultures I believe are deeply compatible. Japanese art, with its sense of restraint, of the precise gesture and of respect for what surrounds us. French craftsmanship, with its taste for detail, elegance and work well done. This alliance sums up the way I work.

The vision
What I call a successful project.
Intuitive
You can use it without a manual.
Simple
The opposite of over-engineering: only what serves.
Fast and efficient
Every second counts, on every screen.
Beautiful and memorable
When the project calls for it, it leaves an impression.
Reliable
It works exactly as intended.
On time
Delivered on schedule, with no extra cost.
When all of this comes together, that is a 100% success. It is what I aim for, on every project.
The ambition
Build step by step, and think big.
I created Seicho to build a company in my own image and take it far. I love taking a step back: thinking strategically, linking every technical choice to a business’s goals, anticipating what comes next.
My ambition is simple: for every client to recommend Seicho. A reputation is earned project after project, through the quality of the work and the trust placed in it. That is the only growth that truly matters.
Roots
From the Paris region to west Lyon.
- Paris region
- Évreux
- Paris
- Salon-de-Provence
- Chaponost
Originally from the Paris region, with Brittany close to my heart, I have lived in Évreux, Paris and Salon-de-Provence, and the Air Force took me across much of France. I came to the Lyon area for a while, learned to love it and put down roots here.
A father of two, I now grow Seicho from Chaponost.
