About this grant

Mazarine Ventures is a Chicago-based venture capital firm investing in early-stage companies with innovations that help their customers manage water quantity and/or quality risks across B2C, B2B, and B2G markets. The firm invests at the pre-seed and seed stages, backing exceptional founders early—often before their companies are widely recognized. Water is increasingly becoming a critical challenge for industry and society, and technology helps manage water-related risks before they become crises. Mazarine's portfolio spans multiple sectors where managing water and wastewater related challenges is increasingly critical, including testing and monitoring, software solutions, and treatment and remediation technologies. The firm also operates Mazarine Climate, a climate adaptation fund focused on similar water-related challenges.
