We invest in the AI-native data stack for hydroclimatic risk.

Hydroclimatic risk — floods, droughts, storms, and sea-level rise — is repricing assets in real time. Insurers are withdrawing from flood- and storm-exposed markets. Sovereigns and municipalities are issuing debt conditioned on water and coastal risk. Operators are losing production to droughts that empty reservoirs, floods that close ports and rail, and storm surge that strands coastal capex — on timelines 20th-century hydrology said were decades away.

Disclosure regulation, insurance repricing, and direct balance-sheet exposure are three independent forcing functions. Institutions must disclose, insurers must reprice, and operators must protect cash flow. The instrumentation priced to that reality has not caught up — creating recurring, defensible demand for the companies that close the gap.

For the first time, satellite cadence, sensor cost, and model capability are all converging. A pipeline corridor, a coastal port, a property portfolio, or a hydroelectric reservoir can now be observed continuously and reasoned about probabilistically.

We back companies turning that capability into products operators, insurers, and regulators actually buy — especially the recurring analytics and decision-software layers where high gross margins and enterprise contracts give early-stage companies room to compound.

The most sophisticated climate money is no longer concentrated in mitigation alone. Sovereign wealth funds, reinsurers, infrastructure investors, and a new generation of specialist venture firms are moving decisively into adaptation — because that is where the spending is already happening and where the risk is already being priced.

Mitigation remains necessary. Adaptation is now inevitable, and it is compounding faster. The capex required to harden infrastructure, redesign supply chains, and rebuild risk models is measured in trillions — and the buyers (insurers, operators, lenders, regulators) are procuring today, not waiting on policy.

Software, sensing, and intelligence will capture a structural share of that flow. The category is still being defined, and Mazarine Climate is built to bring a specialist lens to it before the market becomes crowded.

The 'too much water' problem — sea level rise, storm surge, and extreme precipitation — is often more immediately destructive than scarcity because it is acute, infrastructure-damaging, and system-wide. Excess water events rapidly overwhelm design thresholds, causing floods, slope failures, and cascading disruption across transport, utilities, and urban systems. These failures are sudden, visible, and increasingly translate into insurable and investable risk.

Water scarcity is a major global challenge, but it is harder to invest in at scale. Solutions like desalination, reuse, and distribution sit within complex regulatory, political, and often human-rights constrained environments, which slows deployment and limits scalability. As a result, water quality and excess-water risk tend to offer clearer commercial pathways. The key exception is scarcity tied to power generation (hydro and thermoelectric), where reliability directly drives infrastructure demand. This framing underpins Mazarine Climate's thesis and prioritization.
