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.

The repricing has begun. The instrumentation priced to it hasn't. That asymmetry — between how fast hydroclimatic risk is moving and how slowly the data, models, and software underneath it are catching up — is where outsized returns and outsized impact live together.

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.

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. That is the market forward-thinking climate capital is pursuing, and the market Mazarine Climate is built for.

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.
