What We Are Not

Five deliberate boundaries — and why defining by negation is the honest way to read a thesis.

What We Are Not

A thesis that excludes nothing isn't a thesis. Here are five things Mazarine Climate deliberately isn't, and why each boundary makes the fund sharper.

1. Not a water fund

"Water" hides several businesses behind one word. We took it out of the thesis on purpose; hydroclimatic risk is a category with edges.

2. Not investors in water utilities

Plenty of good companies sell operational tools to water and wastewater utilities. Worthy work, not ours. The utilities we serve are the ones water threatens, like power.

3. Not a bet on a reluctant buyer changing its mind

We prefer demand that doesn't need to be manufactured. Non-discretionary means a regulator, lender, or reinsurer has already made the decision.

4. Not a "resilience" fund

Resilience is a property you claim; adaptation is something you do about a specific hazard. We fund the verb, not the adjective.

5. Not a vehicle for "water is life"

That's a moral claim, not an investment thesis. We take scarcity seriously only where it is a line item on someone's balance sheet.

Mazarine Climate is narrow by design: early-stage, risk-factor led, specialist, and outside the water industry. Precision is the product.

Mazarine Climate tracks 159+ early-stage companies classified as hydroclimatic risk.
