Key challenges we tackle
How do we help?
Digital sustainability: where sustainability meets usability
Every pixel has a footprint. In an era where digital products are the primary touchpoints for global change, your interface is a powerful tool for impact. We architect sustainable UX/UI experiences that reduce digital waste, ensure 100% inclusion, and nudge users efficiently.
Whether you are a B Corp, climate tech SaaS company or a circularity pioneer, your digital presence should reflect your values, not contradict them.

Our sustainable design pillars
Low-carbon digital design
The internet is responsible for nearly 4% of global greenhouse gas emissions. Most of this is driven by "heavy" design choices. We use low-carbon web design principles to ensure your platform is lean, fast, and green.
Radical accessibility (WCAG 2.2)
Sustainability is nothing without inclusion. We design to the highest WCAG 2.2 standards, ensuring your product is accessible to everyone and ready for the European Accessibility Act (EAA).
Behavioral design for impact
We use nudging for good. By applying behavioral psychology to UX, we help your users make better choices - whether that’s opting for a lower-carbon shipping method, reducing food waste, or completing a complex TNFD data entry without friction.

Our UX/UI design process
Phase 1: Impact discovery & UX audit
We start by understanding your mission. If you have an existing product, we perform a UX audit, identifying where digital friction is leading to drop-offs and where conversion can be optimized. If the budget allows, we also involve your target audience in this phase to avoid assumptions.
Phase 2: user journey mapping, information architecture and wireframing
We map out the leanest possible path to conversion. Every unnecessary click is a waste of energy and a risk to user retention. Our wireframes focus on information hierarchy. We test this hierarchy and journeys with the users and optimize for efficiency.
High-fidelity UI & prototyping
We create visually stunning, professional interfaces that build trust. We don't follow trends; we create timeless, inclusive designs that won't need a 'rebrand in two years (the ultimate form of digital waste).
Hand-off & implementation
A design is only as good as its execution. We provide our development team with comprehensive design systems and documentation, ensuring a pixel-perfect transition from Figma to the browser.
