We invest where innovation drives demand.

Modernization is consuming unprecedented power, which we believe marks an inflection point for transformative investment in the global energy system.

Opportunity Meets Experience

We believe that our current moment is one of tremendous opportunity.

As energy use cases proliferate, mass electrification takes hold, and the first phase of Artificial Intelligence infrastructure is deployed, we are witnessing the limits of a twentieth-century system operating under twenty-first-century conditions. Meeting this moment requires new supply, modernized infrastructure, and a system built for reliability, efficiency, and climate resilience.

This build cycle creates a target-rich opportunity set within the “missing middle.” We invest in companies that we expect to bridge the gap between innovation and deployment, turning critical energy solutions into scaled execution.

Our E³ Compounding Approach

E³ = Energy × Enablement × Endurance

Our investment approach multiplies three dimensions. We have seen repeatedly that a company strong in all three can create compounding value for its customers, community, and capital providers.

Our Sector: ENERGY

We focus exclusively on the energy economy, where structural forces are reshaping how power is generated, transmitted, transformed, stored, and consumed. More than a thematic allocation, Energy represents our multi-decade commitment to understanding where value compounds in mission-critical markets.

Our Positioning: ENABLEMENT

We back the companies that we believe strengthen the energy system. From companies that design, develop, and deploy new power generation to products and technology that modernize and strengthen the grid, we invest in solutions that sit at critical leverage points where precise improvements create outsized effects. We aim to partner with force multipliers: companies that grow as the system grows. 

Our Selection Criterion: ENDURANCE

We partner with companies that we expect to withstand regulatory shifts, technology disruptions, and market upheavals. The best companies don’t seek to protect themselves from change; they position their offerings to move with it. Endurance is not just a matter of survival, but an opportunity to compound value through volatility.

In a world increasingly defined by finite resources and focused on climate resiliency, we believe the strongest companies will be those that scale through efficient operations and responsible practices. Through active partnership, we seek to build durable operations and sustainable businesses for the long term.

Stewards Of The Future

We endeavor to build an institution that is designed to last. That starts with how we operate and extends to what we expect from the companies we back.

Our Team

We hire individuals who can handle complexity while relating clearly. We expect intellectual honesty, operational rigor, and mutual respect. A team that works well together deepens its advantages over time, so we invest in career growth, mentorship, and a culture where talented people stay for the long run.

Our Standards

We maintain high standards of ethical conduct because we know that shortcuts erode trust. Anti-bribery, anti-money laundering, and regulatory compliance are operational basics. We seek to partner with companies committed to acting responsibly, treating people fairly, and contributing positively to society. We see these not as constraints, but conditions for enduring returns.

Our Portfolio

We advocate for governance structures that support long-term value creation: exceptional leadership teams that bring hard-won experience to complex situations, operational discipline that strengthens through market cycles, and a clear-eyed view of how business practices affect not only the communities where our companies operate, but the world for our future generations.
