Mazarine Ventures

Mazarine Ventures invests exclusively in solutions addressing water risk, spanning scarcity, water quality, and climate resilience. The firm targets early-stage, seed, and growth companies whose technologies or business models center on treating, monitoring, or managing water resources. This singular focus distinguishes it from broader climate-tech or environmental funds that treat water as one vertical among many.

While Mazarine does not publicly detail its sourcing methodology, the firm's narrow water-only mandate and Chicago headquarters suggest origination relies on specialized technical networks in hydrology, municipal water procurement, and industrial water treatment. The firm's minimal public-facing presence points toward relationship-driven deal flow through engineering and policy ecosystems rather than through broad marketing or conference circuits.

Publicly available information on Mazarine's co-investment practices is limited. As a sector-specialist venture firm, it is structurally positioned to collaborate with larger infrastructure and generalist climate funds on water-related deals where its technical diligence adds value. However, specific co-investment partnerships have not been disclosed in reviewed public sources.

Mazarine Ventures has not publicly disclosed its assets under management, total capital deployed, or the size of its investment team. The firm operates without a public LinkedIn presence and maintains an intentionally lean external profile, making it one of the more opaque specialized micro-funds in the water sector.

Mazarine's entire mandate is water-focused, implying that any sector or technology not directly tied to water scarcity, quality, or climate resilience falls outside its investment scope. General software, consumer internet, healthcare, and other non-water climate verticals are not part of the firm's investment thesis.
