Mazarine Ventures

MariaMazarine Ventures is a Chicago-based venture capital firm dedicated to addressing the global water crisis through technology. Founded in 2018, Mazarine exclusively invests in early-stage startups that are developing innovative solutions for managing water and wastewater-related risks across various industries. These sectors include agriculture, aquaculture, climate tech, and industrial applications, among others. The firm operates multiple funds, each with a unique focus. Fund II, for instance, targets companies with proven commercial traction—often nearing $1 million in annual sales—and intellectual property rooted in fields like chemistry, data science, and materials science. Mazarine typically leads seed and early Series A rounds, cutting checks between $25,000 and $500,000, and often continues to support its portfolio companies through follow-on investments. Mazarine’s investment strategy is centered on mitigating critical risks—such as public health, environmental protection, and business continuity—posed by water scarcity and quality issues. The firm’s approach extends beyond financial backing; it leverages a network of experienced operators and co-investors to provide strategic support, helping startups scale and achieve meaningful impact. The leadership team, including co-founders John Robinson, Pete Nassos, and Anders Hallsby, brings decades of experience in commercializing water and wastewater technologies. Mazarine’s rigorous focus on ESG (Environmental, Social, and Governance) metrics underscores its commitment to not only financial returns but also substantial environmental and social impact​. wll do on Thu
