Introducing 9Zero Capital

The climate transition needs better capital. We're building it.

9Zero Capital is an early-stage climate investment syndicate backing pre-seed and seed-stage founders tackling the hardest problems in the energy transition. We invest in exceptional companies wherever we find them. Our edge is the 9Zero community, and we bring all of it with us.

What we do

Capital that comes with context.

The best climate founders don't just need capital. They need investors who understand the problem they're solving, the market they're entering, and the people trying to stop them. That's a different kind of investor.

9Zero sits at the intersection of a global climate community and a growing network of operators, scientists, and founders who've built, broken, and fixed the systems you're working on. When we invest, we're not just writing a check. We're opening a door.

How it works

Deal-by-deal. No blind pools. No guessing.

9Zero Capital operates as a syndicate. Each investment is a standalone vehicle: participants see every deal, choose whether to join, and know exactly where capital is going.

We follow, never lead. The best climate investors are already leading these rounds. Our role is to bring aligned capital alongside them, at the right stage, in the right companies. We back pre-seed and seed stage founders working on the energy transition. 9Zero community members have a natural advantage, because we know them, their work, and their world. But great founders get our attention wherever they're building.

Who we back

Built for founders by founders who want more than money.

Every company 9Zero Capital backs gets immediate access to the relationships, resources, and expertise that the 9Zero community has spent years building. Peer founders who've been where you are. Operators who've scaled what you're scaling. A network that's genuinely invested in seeing you win, because now, they literally are.

Our first investment

We have already made our first investment, Piq Energy, a 9Zero member company tackling one of the most critical challenges in the energy transition. We are proud to back them and excited by what they are building.

“There's no better place to build in climate and energy than 9Zero. The space, the people, the community of other founders, investors and other aligned companies, and the network are exactly what early-stage companies need. We've been fortunate to call their SF location home since 2024, and we're thrilled to now have 9Zero as investors too!”
Dr. Tom Nudell, CEO, Piq Energy
