Sandbrook Capital

We are a private investment firm dedicated exclusively to building businesses that help transform the world’s energy infrastructure. By partnering with courageous entrepreneurs that share our drive to fight climate change, we create impactful companies that move us closer to a net-zero world and deliver strong returns for our investors.

Our founders have each accumulated decades of experience operating, funding, and supporting climate infrastructure companies. They have worked together for over 17 years to formulate and refine a shared investment philosophy that has supported the growth of industry leaders such as Pattern Energy, Silver Ridge Power, and SeaJacks Ltd. In 2021, this partnership evolved into Sandbrook Capital – a firm built from the ground up to help exceptional entrepreneurs tackle the greatest challenge of our time.

As of summer 2025, Sandbrook and its co-investment LPs have committed over $2.3 billion in equity capital to leading climate infrastructure companies including NeXtWind, rPlus Energies, Cloverleaf Infrastructure, Havfram, VoltWise and Intellirent.
