L'écologie préserve la planète , notre
agence web conserve les humains
We build Webflow websites for impact companies and for players in energy, mobility and ESG consulting. Websites that prove your impact and use as little energy as possible.




Does your website really
tell your impact story?
Your results sit in a PDF report nobody opens. On the website, visitors only see promises.
Without proof or sources, a green promise raises doubts. Your clients and investors check more and more.
Autoplay videos, heavy images and unnecessary scripts. The website consumes more than your message suggests.
Businesses, local governments and individuals each look for an answer to their own need. A single homepage speaks to no one.
We've had [+250] projects to get better,
so yours can start with peace of mind.
A website that proves your impact
without weighing it down
A sustainable website is judged on 2 things, what it demonstrates and what it consumes. We work on both from the design stage.
Tons avoided, projects funded, measurements taken. Every figure comes with its source and date, all managed in the CMS.
Dedicated pages for businesses, local governments or individuals. Everyone understands what you do and why.
Compressed images, no autoplay video and few scripts. We measure the EcoIndex of every page before launch.

Frequently asked questions
about eco-designed websites
What is an eco-designed website?
It's a site that uses as few resources as possible, without losing quality.
- Compressed images.
- No autoplay video.
- Few scripts.
We measure the EcoIndex of every page before launch, with a target grade of A or B.
How do we show our impact without greenwashing?
With evidence. Every impact figure (tons avoided, projects funded, measures taken) is shown with its source and date, and managed in the CMS to stay up to date.
A sourced claim reassures your clients as much as your investors, who check more and more.
Can an eco-designed site still look great and convince?
Yes. Eco-design removes the excess, not the emotion. Strong art direction, good typography and well-chosen visuals weigh little and make a bigger impression than heavy videos.
Your site also gets faster, which helps both SEO and conversion. See our approach to web design.
Can we speak to businesses, local authorities and individuals at the same time?
Yes, with a dedicated page for each audience. Each one understands what you do for them, in their own words and with their own stakes.
Your content stays organized in the CMS, so it's easy to keep up to date.
Have you worked in the ecological transition before?
Yes. We work with these companies, among others.
- R3, a consulting firm in CSR and energy performance.
- Sensinov, which helps commercial building managers cut their energy use.
- Lita, an impact investing platform.
