• $50M Series B funding led by Lowercarbon Capital boosts Crux’s total raised to $77M, accelerating clean energy capital markets infrastructure.
• Platform growth and adoption: Crux now connects 630+ market participants and has facilitated billions in tax credit transfers and $11B+ in debt capital raises.
• Expansion strategy: Funds will enhance software, AI-powered deal execution, and data-driven market intelligence across tax credit and debt markets.

Crux has closed a $50 million Series B round led by Lowercarbon Capital, with returning support from Andreessen Horowitz, Ardent Venture Partners, CIV, New System Ventures, and The Three Cairns Group, and new investors including Giant Ventures, Acrew Capital, Liberty Mutual Strategic Ventures, MassMutual Ventures, and OMERS Ventures.

This funding brings Crux’s total to $77 million and marks a critical milestone in its mission to modernize capital markets for the clean economy.

“This funding allows us to build the central capital markets platform for the clean economy,” Crux stated. “We’ll continue to build liquidity, efficiency, and intelligence into tax credit transfers and debt raises.”

Market Context: A Clean Energy Capital Crunch

The funding comes amid soaring demand for clean energy and American-made components, with trillions in capital needed to meet new manufacturing, electrification, and data infrastructure demands. Yet, capital markets remain disjointed and inefficient.

“Developers and manufacturers struggle with team bandwidth, uncertainty on financing options, and long, costly processes to find the right capital,” Crux explained. “At Crux, we are building central capital markets infrastructure for the next century of American clean energy and manufacturing.”

Platform Expansion: Scaling Impact

Crux’s network now connects over 630 developers, manufacturers, tax credit buyers, lenders, and intermediaries. It plans to grow that to 1,000+ counterparties by year-end.

Previously disconnected sectors — like nuclear, solar, lithium, and geothermal — now converge via transferable tax credits, enabling a broader and more centralized market.

Debt Marketplace Momentum

Crux’s newly launched debt marketplace includes 100+ project sponsors seeking $11B+ in capital. Its investor network — comprising 90+ banks, funds, and institutions — issued $1B in debt term sheets last quarter alone.

“We’ve always envisioned a platform where participants can raise and deploy many different types of capital,” said Crux. “Over the next 18 months, we will broaden our offerings to support new transaction types across the capital stack.”

Software and AI: Building the Backbone

Crux plans to deploy the Series B funding into its software platform, focusing on embedded AI workflows, reusable data rooms, and tools for capital planning and post-close reporting.

“Powerful software, embedded proprietary data, and AI will help our clients and partners do more deals faster.”

Intelligence-Driven Capital Markets

Crux’s market intelligence reports, based on $30B+ in tax credit transactions, are now benchmarks in the sector. These insights are powering tools like Cruxtimate, the first modeled pricing tool for transferable tax credits.

“With this funding, we will build new datasets, publish extensive research, and embed more of this intelligence into our platform.”

Bottom line for executives:

Crux is positioning itself as the go-to capital markets infrastructure for the clean energy transition — a crucial lever as demand accelerates, policy evolves, and financial complexity increases.
