Giving a circular battery startup a presence that matched its ambition
Rebaba is a Stockholm-based startup building circular battery energy storage systems from EV waste. They needed a website that signaled maturity to stakeholders and partners — not a startup in concept mode. I designed and shipped it.

From concept pitch to credible company
Rebaba had a pilot project underway and a story worth telling — upcycling battery waste from the EV boom into circular energy storage systems. But their old website didn't communicate any of that. It looked like a concept, not a company.
With a diverse audience of technical partners, potential customers, and investors, they needed a site that could speak differently to each group without losing coherence. They also needed it fast.
Rebaba's previous website — the starting point
Three design priorities
Communicating maturity through visual identity
I designed each page in Figma before building in Lovable, an AI-powered development tool. High-quality visuals — including custom iconography and curated photography — told Rebaba's origin story: a response to the battery waste crisis driven by the EV transition. Every visual choice pushed toward "established partner," not "early-stage startup."

Structuring product offerings for two audiences
The "Our Solutions" page uses separate tabs — a technical spec sheet and a use-cases view. Engineers can jump straight to product specifications. Non-technical stakeholders get a clear, accessible overview of what Rebaba actually does and why it matters. One page, two entry points, no dead ends.
Articulating mission through storytelling
New "Partners" and "Impact" pages gave the mission room to breathe. I connected Rebaba's work to broader environmental stakes — EV waste, mining impact, battery circularity — and framed their competitive advantages clearly for a European partnership audience. The goal wasn't to impress; it was to make the case.

A website the founders were proud of
Rebaba's founders described the new site as a step-change in how they communicate. Stakeholders who had struggled to understand the product quickly grasped both the technology and the mission. Website traffic increased by over 1000% in March 2025 compared to December 2024 — a signal that the improved clarity was reaching the right people.
The site is live. See the full result — product pages, impact messaging, and the dual-audience solution structure.

AI-assisted development
Lovable streamlined the build significantly, but I compensated for its limitations by designing every page in Figma first — a meticulous but worthwhile extra step. In future projects, I'd also bring in a human engineer to pressure-test technical feasibility earlier.
Personas and QA
Time constraints meant I couldn't fully develop the stakeholder personas Rebaba had started, and QA testing involved only two people before launch. More usability testing and an accessibility audit would have strengthened the final product.
What this project reinforced
Working solo on a real client with a live deadline sharpened how I prioritize. When you can't do everything, you design the most critical things well. The Figma-first approach — even when using AI build tools — proved its worth: it forced clear design decisions before touching code, which prevented scope creep and kept the vision intact through to launch.
This project also deepened my interest in designing for complex, multi-stakeholder audiences. Getting non-technical readers to genuinely understand a technical product is one of the more interesting design challenges there is.
