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.R.E. (Finance, Insurance, Real Estate), and Power Generation. Our lens is Industry 4.0: the sensing, data, AI, and decision software that turn climate-driven water risk into something operators, insurers, and regulators can actually price, monitor, and act on.
Insurers are withdrawing from entire markets. Sovereigns are issuing climate-conditioned debt. Operators are losing production to drought, floods, and heat that 20th-century models said wouldn't happen for decades.
The repricing has begun. The instrumentation hasn't. That asymmetry is where outsized returns and outsized impact live together.
For the first time, satellite cadence, sensor cost, and model capability are all converging. A river basin, a port, or a semiconductor fab can now be observed continuously and reasoned about probabilistically.
We back companies turning that capability into products operators, insurers, and regulators actually buy.
Mitigation is necessary. Adaptation is now inevitable. The capex required to harden infrastructure, redesign supply chains, and rebuild risk models is measured in trillions.
Software, sensing, and intelligence will capture a structural share of it. That is the market Mazarine Climate is built for.
Many excellent investors back the slow-moving, high-CAPEX municipal and industrial treatment stack — activated sludge, nutrient removal, membrane filtration, anaerobic digestion, desalination, PFAS treatment, and legacy “digital water” like SCADA and utility monitoring. We respect that work and expect areas of overlap, but it is not our game. Our focus is the software, sensing, and intelligence layer that prices, monitors, and acts on hydroclimatic risk — a different buyer, different economics, different problem.
We are notably less focused on companies producing “new” water — Atmospheric Water Generation, large-scale desalination, and similar supply-side innovations. The science can be remarkable, but the moment you sell delivered water you enter the world of tariffs, utilities, regulators, and local politics — pricing inertia and bureaucracy that rarely fit venture timelines.
Most of our attention sits on the “too much water” side of the ledger: floods, storms, surge, and the cascading hazards that follow. Where we engage on scarcity, it is narrowed to power generation — snowpack-dependent hydro and cooling-dependent thermoelectric assets facing existential water-availability risk, where the buyer pays for resilience, not for delivered water.
