John Robinson at Mazarine Ventures frames his investment thesis as "water is a risk" rather than "water is life," investing through four risk lenses (public health, cost, environmental protection, and business disruption) to find water and climate deals across non-obvious sectors like property, finance, and insurance rather than just utilities. He operates a four-lane platform including an internal incubator (Mazarine Labs), two funds for different stages, and a dedicated impact vehicle (Bluehouse), while using a structured "CIA" evaluation framework that assesses founders' Character, Intellect, and Access to various forms of capital.
