About Ecofix Gas & Power
Ecofix Gas & Power is a new player in the energy market. Founded in summer 2024, launched in May 2025. Their mission: to make energy smarter, simpler and more affordable.
Challenge
Big dreams, tight deadlines
“We want to make dynamic prices for electricity really transparent and accessible to everyone. So that our customers can benefit from the very lowest tariffs.” Ecofix CEO Yassine Hasnaoui's ambition is clear.
If you make that promise to your customers, you need to provide them with the necessary digital tools to do so. With a user-friendly app at the heart of your digital strategy. The founders entrusted the development of that Ecofix app to us.
But the scope was even broader. We were given the opportunity to design the entire customer experience: branding, digital user experience, website and a customer portal.
The deadline was tight. It was up to us to work together with the four founders to get everything ready in time.

* Logo, colour palette and some declinations. In just four days, we designed Ecofix's corporate identity from scratch.
Solution
One solution for Android, iOS and the web
We shaped a branding that stands out. And we consistently translated that branding in all things digital.
With Flutter, we developed a single solution for Android, iOS and the web. With Microsoft Azure Cloud, we guarantee a scalable and secure solution that grows with Ecofix GP and their ambitions.
Some of the key functionalities we integrated into the app:
- Daily consumption monitoring
- Manage smart devices
- Track current market prices
- Planning energy consumption
- View and pay invoices

ACA Group helped us realise our vision quickly and efficiently. The collaboration was fantastic.

Approach
Finding the balance between a quick time to market and quality
To get a head start, we carried out the branding and technical processes in parallel.
“Above all, we had to be very pragmatic. Fast and efficient. Time to market is everything for start-ups”, says Studio lead Johan Steppe.
“We worked together directly with the founders. And they wanted to go forward quickly. They have a clear vision and the guts to make bold decisions. It's up to us to bring that to life in the shortest possible time. Our job is to get gold on the table right away.”
“In four days we had the branding in place. Including intake, workshops and a survey. After another three weeks, we had designed the entire app and portal. The website layout followed just four days later.”
Jurgen Geys, Mobile lead: ‘We are proud of what we have achieved together with Ecofix. The mutual understanding is great. We trust each other 100%.”
‘But the road towards it was intense. With tough discussions at times. They obviously want to go fast, but some technical decisions you really have to think through. That's the role we as developers have to play. Because we know that the technical foundation you lay now are so important. Sometimes we really had to convince them of that. Guys, if we don’t get this right, you are guaranteed to have problems if you scale up. At the same time, we had to be as lean and mean as possible to get everything done.’
An inspiring entrepreneurial story. Four founders who spoke their mind. All mixed with working together at 200 kilometres per hour. Awesome!

Together with Ecofix, we will continue to build new tools to support both their customers and employees.
Jurgen: “New projects are already in the pipeline. Including a portal for their salespeople and representatives.”
Johan: “If you are an entrepreneur and you are looking for a like-minded party that can speed up your ideas: that's us. We help you take big steps quickly in your digital ambitions.”
