We don't invest from the sidelines.
We work alongside early-stage solar founders as co-builders — putting our time, network and capital behind companies that can expand what solar makes possible.
Capital is only one part of the deal.
Early-stage companies rarely need money alone. They need people who understand the market, know who to call and are willing to help build.
Time
Put senior operating capacity to work.
Build systems, solve problems, open doors and help the team execute.
We don't need you to have it all figured out.
We don't need everything to be working.
Sometimes that's why we're here.
We look for opportunity and leverage.
Not perfection.
Something worth building, fixing or moving forward — where our involvement can genuinely change the outcome.
One
partner.
More
ways to
create
value.
Commercial, operational, network and capital support can work together around the problem that matters most.
ALL IN SOLAR
Build. Sell. Connect. Scale.
The network is part of the investment.
We are built inside the solar ecosystem. Our value is knowing who matters, why they matter and how to open the right conversation.

Our first
investment is time.
With time we build trust.
And with trust we can deploy more capital.
Early is not a problem.
Your stage doesn't determine whether we can be useful.
Early does not mean too early.
What does your company need next?
We start with the priority — and build from there.
Already building inside the solar ecosystem.
We work with founders and companies across the solar ecosystem — helping turn ideas into products, projects, partnerships and businesses.
