Mazarine Climate
Investment Thesis

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

Mazarine Climate is a specialist VC on the adaptation side of climate-tech. We focus exclusively on hydroclimatic risk — floods, droughts, storms, sea-level rise, and the cascading hazards they trigger — and back early-stage companies serving the four sectors absorbing the most pain and spending the most to manage it: Linear Assets, Coastal Infrastructure, F.I.RE. (Finance, Insurance, Real Estate), and Power Generation. Our lens is AI applied to the Industry 4.0 toolbox: sensing that produces high-resolution ground-truth data, analytics that understands it as priced risk, and decision software that acts on it. Effective AI is built on better data — we back founders across sense, understand, and act.

01

The buyer is compelled, and balance sheets aren't ready.

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.

02

Data is the unlock — and AI finally makes it tractable.

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.

03

Adaptation is where forward-thinking climate capital is going.

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.

04

The part of water risk that actually trades.

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, atmospheric water generation (AWG), and distribution sit within complex regulatory, political, and often human-rights constrained environments, which slows deployment and limits scalability. The technologies often work, and the founders behind them are usually passionate — but the addressable market is frequently captured by public policy, subsidized infrastructure, or incumbent industrial players, not by venture-shaped software economics.

As a result, Mazarine Climate is generally not interested in scarcity-focused solutions unless they are directly tied to power generation — hydro and thermoelectric — where reliability directly drives infrastructure demand and a compelled buyer already exists. Water quality and excess-water risk otherwise tend to offer clearer commercial pathways. This framing underpins our thesis and prioritization.

Scarcity matters, and we tip our hat to everyone working on it. But we have found that many investors conflate importance with investability. 'Water is life' is true — and it is also a poor reason to write a venture check. That is why our primary focus stays on the 'too much water' headache: it is where the risk is most immediately priced, the buyers are most compelled, and the venture-shaped returns are most achievable.

The academic case

The science behind the thesis.

Our conviction that hydroclimatic risk is the defining investable variable isn't a hunch — it tracks the peer-reviewed work of the MIT Joint Program on the Science and Policy of Global Change, one of the most authoritative voices in integrated climate and economic modelling.

Hydroclimatic analysis of climate change risks to global corporate assets in support of deep-dive valuation

Strzepek, K., C.A. Schlosser & J. Goudreau — Joint Program Report Series, April 2021

The MIT team argues that investors, lenders, and insurers still lack quantitative tools to see which companies will endure climate change and which won't — and that hydroclimatic risk (flood and drought) is among the key climate-related risks to business. Using an ensemble of climate scenarios from the MIT Earth Systems Model combined with an enhanced version of the World Bank's Climate Risk Hydro Indicators, they assessed the real global facilities of an anonymous multinational ("GloCorp").

The findings are stark: by 2030, 61% of all facilities face Medium or High climate risk — rising to 90% by 2050. The instrumentation and data to price that risk barely exist today.

This is exactly the asymmetry Mazarine invests behind: hydroclimatic risk is repricing corporate assets in real time, the buyers (insurers, lenders, operators) need quantitative tools they don't yet have, and the AI-native data stack that supplies those tools is where we deploy capital. The MIT research is independent academic confirmation of our thesis.

Five families of climate risk

All are serious. One is already dominant.

Pyroclimatic, aeroclimatic, thermoclimatic, and bioclimatic risks are real, growing, and investable on their own timelines. Hydroclimatic risk is the family already driving the majority of today's insured losses, displacement, and stranded capex — and the instrumentation priced to that reality barely exists yet.

Investability

All five are serious risks. The question is where investors see ROI alongside impact.

Reading the gradient
Most investable

Clear buyer pain, measurable losses, and software-heavy economics. Venture-scale returns are visible because the risk is already repricing assets today.

Selective

Real impact and real capital needs, but narrower VC windows. Returns depend on timing, policy, and whether a software layer can capture value.

Least investable

Important for society, yet mostly funded by public budgets, hardware, or regulated utilities — not the venture-return profile we target.

The framing: every step left-to-right is still climate impact, but not every step is where a specialist VC sees its next-decade returns. We concentrate on the left because that is where "ROI alongside impact" is most actionable.

Any investment in climate adaptation — whatever the vertical — is inherently impact investing. The real question is where the returns are in the next decade.

Least investment-grade does not mean unimportant, or that capital won't flow. Heat adaptation will attract serious money through public budgets, utilities, and infrastructure balance sheets — it is simply, for the most part, unworkable for venture-scale returns. We price that distinction honestly rather than pretend it away.

Cross-cutting impact

These risks cut across every sector — and well beyond insured losses.

The five families don't sit neatly inside one industry. They surface simultaneously across finance, infrastructure, energy, agriculture, logistics, real estate, and the public sector — and they show up on dimensions that balance sheets alone don't capture.

Public health & safety

Heat mortality, water-borne disease, air-quality events, and emergency-response load on hospitals, utilities, and municipalities.

Economic development

Stranded capex, sovereign and municipal credit downgrades, repriced insurance, and rising cost of capital in exposed regions.

Business disruption

Supply-chain breaks, plant and grid outages, port and rail closures, agricultural yield shocks, and idled production.

Biodiversity & ecosystems

Habitat collapse, fishery and forestry decline, pollinator stress, and nature-related disclosure exposure under TNFD.
