Brownee is a comprehensive B2B platform designed for companies committed to sustainable energy and global ESG (Environmental, Social, and Governance) standards. Many organizations struggle to translate vague sustainability goals into actionable strategies. Our task was to design an end-to-end digital ecosystem that assesses a company's current state, suggests high-impact tasks, and tracks real-time progress. We turned complex global objectives into a clear, gamified management tool where every business decision is reflected in a specialized "Brownee Score," providing stakeholders with absolute transparency regarding their ecological and social impact.
