Redefining the diligence process: How AI and industry expertise are powering a new era of project finance

September 18, 2025

In project finance, diligence has long been a bottleneck. Critical details are buried in sprawling documents housed in generic data rooms. Hours of costly professional review go into hunting for the same handful of terms — such as the offtake counterparty in a power purchase agreement (PPA), the jurisdiction of a project entity, or the date of a certificate — that determine project risk and shape negotiations. The process is slow, opaque, and oftentimes frustrating for everyone involved. 

At Crux, we believe diligence can be efficient and intelligent. That’s why we’ve been steadily expanding our Diligence Suite, building the tools that make a new standard of diligence possible.

From standards to intelligence

Earlier this year, we introduced the diligence verification tool to bring greater structure to the diligence process — organizing files and validating them against market-standard checklists developed in partnership with 35+ leading law firms and insurance brokers. That work created a consistent foundation for tax credit and technology-specific diligence. 

Now, we’re taking the next step.

What’s new: Document Intelligence with NRF

We’re expanding the Diligence Suite to include Document Intelligence, an automated capability that leverages large language models (LLMs) to identify and surface the critical details that matter most in clean energy transactions.

In collaboration with Norton Rose Fulbright (NRF), we defined a taxonomy of the key terms and concepts advisors look for during diligence. Document Intelligence applies LLMs to extract those terms directly from documents and make them instantly visible in the workflow.

For example: when reviewing a power purchase agreement, Document Intelligence can automatically flag the offtake counterparty, jurisdiction, or contract tenor — details that would otherwise require careful reading across lengthy documents.

Beyond intelligence: Collaboration built in

Diligence isn’t just about surfacing information; it’s also about how counterparties work together. That’s why the Diligence Suite now includes:

  • In-line Q&A: Instead of sending questions back and forth over email, counterparties and their advisors can ask and answer directly within the context of a diligence checklist item. This ensures questions don’t get lost and responses stay anchored to the right reference material.
  • Trackable buyer document requests: Instead of juggling spreadsheets, buyers can make document requests from directly within the diligence checklist. Sellers can respond in the same place, creating a single, trackable record of what’s requested, delivered, and outstanding.
  • Buyer status review tracking: Within the checklist, sellers can mark the status of each item as they work through it, giving both sides a real-time view of overall progress. Everyone can see at a glance what’s been reviewed, what’s in progress, and what still needs attention.

Together, these collaboration features transform diligence from a static review into a dynamic, transparent workflow, making it easier for both buyers and sellers to move quickly, reduce misunderstandings, and ultimately build trust.

Scaling across the capital stack

Soon, Document Intelligence will support more than 100 project finance document types and extend beyond tax credits into debt financing and other structures, underscoring Crux’s role as infrastructure for the entire capital stack. Over time, it will do more than surface information — we’re creating capabilities that combine agentic AI and human expertise to deliver faster, clearer, and more trusted outcomes across the entire project finance lifecycle.

Our approach to AI

At Crux, we treat AI as a foundational enabler: working in the background to support verification and extraction today, and over time orchestrating workflows across underwriting and contracting. Our approach is never to present AI as a black box — every use is explicit and traceable, with clear links back to source documents, offering the necessary context to navigate these complex transactions. And because diligence often involves highly sensitive information, we’ve built our systems to protect privacy at every step.

Conclusion

With the expansion of our Diligence Suite, we’re proving that diligence doesn’t have to be slow, opaque, and fragmented. Document Intelligence is one step in a broader shift to make project finance more liquid, efficient, and intelligent, moving capital into the projects that matter most.
