What Who is
Grow Online ?

Grow Online is me, Julien! I have been a young web and design enthusiast for 7 years now.

Grow Online is an initiative on my part to bring back forgotten design methods in the modern web: cleaner and more efficient, we're talking about eco-design. Practices that are not accessible through mainstream editors such as Wix, Squarespace or even Elementor.

I offer you the possibility to design sites and WebApps that are entirely customized without compromise in flexibility compared to today's market giants. Once your site is completed, you hold the cards to grow your online visibility.

Ask me your questions, it's free info Why is eco-design so advantageous?
Julien Scheen, founder of Grow Online.
Me at the Step Entreprendre 2025 end-of-year drinks. This is the wonderful organization that helped me develop my project: Grow Online.

Human expertise above all: AI as an engine accelerator

My specialty? The creation of custom, high-performance, and eco-designed websites. If your project requires creating or revamping your branding, I work hand-in-hand with trusted partners specialized in this field.

My approach is fundamentally human. I use AI on a daily basis, but strictly as a powerful accelerator for development and research. It saves me valuable time, which I reinvest where my added value is irreplaceable: understanding your exact needs and ensuring holistic project management.
