My organisation
Openversum is a Swiss enterprise making safe drinking water permanently accessible in underserved communities. Our gravity-driven household filter with advanced membrane technology removes bacteria and heavy metals — no electricity needed. We train local entrepreneurs, mainly women, who sell, install, and service the filters door-to-door, supported by a digital platform offering microcredit instalment plans, QR- and GPS-based tracking, and simple training tools. With 1,000+ filters deployed in Colombia, 50+ active entrepreneurs, and 100% loan repayment across 300+ micro-loans, we're now scaling to new markets in Latin America and Africa.
