Clean Energy Capital Flows: Crux Secures $50M to Expand Access to Tax Credit & Debt Financing

Founded in 2023, Crux operates a marketplace specifically designed to streamline access to capital for clean energy developers by connecting them with sources of structured financing.

The company has emerged as a key player in the growing market for transferable tax credits and clean energy debt products, offering tools that enable developers to monetize tax incentives and tap into institutional capital.

To date, Crux has facilitated over $1 billion in issued term sheets from more than 90 active institutional participants, including major banks, credit funds, asset managers, insurance firms, pensions, and family offices.

With the Series B funding, Crux aims to expand its platform’s capabilities by integrating artificial intelligence and building out new features to support a broader array of financial products. The company describes its goal as building “the central capital markets platform for the clean economy.”

“We’re in a new era of global competition, with energy demand rising to the highest levels ever observed,” said Alfred Johnson, CEO and co-founder of Crux. “This new round of funding will help us to meet growing energy demand by making it easier, faster, and more affordable for clean energy developers and manufacturers to finance their projects.”

Strategic Investment: Insurance & Pension Funds Back Crux’s Long-Term Vision

The funding round included a mix of returning and new investors. Existing backers Andreessen Horowitz (a16z), Ardent Venture Partners, CIV, New System Ventures, and The Three Cairns Group participated once again, reaffirming their confidence in Crux’s model and trajectory.

Joining them were new strategic investors including:

• Liberty Mutual Strategic Ventures
• MassMutual Ventures
• OMERS Ventures

These investors are affiliated with insurance companies and pension funds that collectively manage hundreds of billions of dollars in assets, offering long-term capital and credibility to Crux’s mission.

Also joining the round were Acrew Capital and Giant Ventures, expanding Crux’s access to venture and growth-stage expertise.

“Today, we are adding insurance and pension investors with hundreds of billions of assets under management,” said Johnson. “We look forward to partnering with our new investors… as we grow the platform and deploy billions into energy and manufacturing infrastructure.”

Platform Potential: A New Financial Engine for the Clean Economy

As global clean energy investment surges—driven in part by legislation such as the U.S. Inflation Reduction Act, which enables the transfer of clean energy tax credits—platforms like Crux are becoming essential tools in unlocking project finance.

By automating and standardizing key elements of the capital raising process, Crux allows developers and manufacturers to efficiently match with investors and lenders, thereby reducing friction, lowering transaction costs, and increasing capital access.

The company’s strategic vision is to serve as the financial infrastructure layer for the clean energy transition, supporting everything from solar and wind installations to manufacturing facilities and grid-scale energy storage.
