In this milestone 200th episode of Walk Talk Listen, Maurice Bloem is joined by Lieselotte (Lisa) Heederik, co-founder and CEO of Nazava Water Filters, an award-winning social enterprise working to provide safe, affordable drinking water to low-income households across the Global South. Lisa shares her personal journey—from a childhood across Bolivia, Kenya, and Yemen to leading one of the only WHO-certified water filter companies in developing countries. Her own experience of dehydration as an infant shaped a life-long mission: making safe water a right, not a privilege. During this wide-ranging conversation, Lisa reflects on how Nazava scaled its impact to reach over 600,000 people in 30+ countries. From the post-tsunami landscapes of Aceh to microfinance-driven solutions in Kenya, she discusses the intersection of women’s empowerment, climate action, and health equity. With humor and humility, Lisa shares her “why,” what keeps her hopeful, and how running trail races mirrors her work as a purpose-driven entrepreneur. Listener Engagement
