How Clean Water Changed an Entire Community

What happens when a successful corporate executive walks away from a thriving career to solve one of Africa’s most pressing challenges? In this episode of Diary of an African Entrepreneur, I sit down with Osen Iyahen, Founder & CEO of Optimal Greening, to discuss her remarkable journey from leading projects at GE and ExxonMobil to transforming lives through sustainable water, sanitation, and renewable energy initiatives across Nigeria. This conversation explores the intersection of entrepreneurship, leadership, sustainability, and social impact. Osen shares how she built an organization that empowers communities with clean water while creating systems designed for long-term sustainability. She also reflects on the challenges of fundraising, leading mission-driven teams, working with governments and donors, and building solutions that genuinely improve lives. Whether you’re an entrepreneur, business leader, policymaker, nonprofit professional, investor, or someone passionate about Africa’s future, this episode offers practical insights into leading with purpose and creating lasting impact.
