My name is Kassim Tijjani Kassim, and I’m building a future where African excellence meets innovation and sustainability. I founded Grandaigne Group, a growing group of companies operating in real estate, fashion, mobility, and smart infrastructure — all focused on creating impact while maintaining a strong sense of identity and luxury.
I hold professional certifications in project management from Google and Oxfordand Renewable Energy from Duke university. I’ve led the development of bold national projects like the Zero Carbon City Initiative and the NADA Reform Framework, both designed to transform Nigeria’s urban and agricultural future through clean energy, smart logistics, and youth-centered innovation.
I maintain active memberships with several respected organizations that align with my values in sustainability, leadership, and professional development. I am a proud member of the American Management Association (AMA), YAMA, and Honor Society®, where I was recognized for academic excellence and leadership. I also hold affiliations with the Green Building Council Nigeria (GBCN), Project Green Society (PGS®), the Global Association of Sustainability(GAoS), the International Society for Development and Sustainability (ISDS), and the Institute for Engineers and Research Publication (IfERP). Additionally, I serve as a Green Ambassador and represent the Management and Strategy Institute (MSI®) as an official ambassador. These memberships keep me connected to a diverse network of forward-thinking professionals and reflect my commitment to continuous learning and global impact
