CHALLENGE: The UN's 17 Sustainable Development Goals require massive private capital to succeed, yet investors lacked visibility into local SDG opportunities and credible market intelligence. The UNDP wanted to bridge this gap by surfacing verified investment opportunities, but the platform needed to feel credible to mainstream investors while staying true to the UN's role as a neutral facilitator. MY ROLE: As design lead, I shaped the platform's core experience, working closely with the research team to align diverse stakeholder needs, defining interaction patterns and information hierarchy, and delivering a system built to scale across global markets. I translated insights from institutional investors, ESG strategists, development economists, and UNDP country teams into design principles: data-first storytelling, trust through transparency, and access to local expertise. PROCESS: We interviewed a wide spectrum of stakeholders to understand what investors needed to act confidently and what the UN needed to maintain neutrality. I led the synthesis of these perspectives into a platform that balances economic clarity with social mission, designing interfaces that let users evaluate risks and returns while understanding local development needs and policy landscapes. Every decision, from data presentation to navigation, was guided by the need to make SDG investment feel like everyday business, not philanthropy. SOLUTION: The final platform is clean, intuitive, and structured for both exploration and decision-making. It combines the approachability of a social impact site with the trustworthiness of a professional financial tool, featuring economic data, tangible case studies, and direct access to local experts. The design scales across regions and continues to evolve as UNDP country offices add new opportunities.
