Crux is the capital markets platform changing the way clean energy and manufacturing projects are financed in the U.S. Crux’s platform, market intelligence, and expert team help developers and manufacturers unlock financing through all stages of project development and operation.
Our team of 85+ is composed of experts in energy, tax, finance, government, and technology. We have raised $77 million in capital from some of the best investors, including Andreessen Horowitz, Lowercarbon Capital, New System Ventures, Overture, Ardent Venture Partners, QED, Canapi, and others. These funds are joined by strategic investors including Pattern Energy, Clearway Energy, EDF Renewables, Intersect Power, LS Power, Orsted, Hartree Partners, Liberty Mutual Strategic Ventures, MassMutual Ventures, and OMERS Ventures.
Energy demand is growing for the first time in 20 years, driven by surging manufacturing, transportation, electrification, and data centers. Simultaneously, hundreds of billions of dollars are being invested in domestic supply chains for critical minerals and components. Developers and manufacturers will require trillions of dollars in capital to meet growing needs.
Before Crux, the capital markets supporting this transformation remained opaque, fragmented, and complex. At Crux, we recognized the missing infrastructure: a central capital markets platform designed specifically for the next century of American energy and industry. By connecting counterparties, providing market intelligence, and streamlining transactions, we unlock faster decision making, lower cost of capital, and accelerated investment.
We are scaling quickly and looking for team members who are eager to combine technical excellence with an AI- and tech-forward mindset.
