F2's Audit Mode Brings Defensible AI to Private Markets Investing

NEW YORK, NY – February 17, 2026 – In a significant move to bolster trust in artificial intelligence within the financial sector, AI platform F2 today launched Audit Mode, a feature designed to dismantle the opaque “black box” surrounding AI-generated analysis. The new capability provides private markets investors with fully traceable and defensible data, ensuring every number can be validated from its final output back to its original source.

Since its launch in September 2025 with a heavily oversubscribed $10 million seed round, F2 has seen explosive adoption, reporting 7x month-over-month growth in platform usage. The introduction of Audit Mode addresses one of the most significant barriers to AI adoption in high-stakes finance: the inability to verify and defend an algorithm’s conclusions. By embedding transparency at the core of its system, the company aims to transform AI from a mysterious oracle into a trusted, accountable co-pilot for investment professionals.

Cracking Open the AI Black Box

The private markets—encompassing private equity, private credit, and venture capital—are notoriously complex, built on mountains of unstructured data from data rooms, financial statements, and legal documents. While AI has long promised to accelerate the painstaking process of due diligence, its adoption has been hampered by a fundamental lack of trust. Most AI tools operate as black boxes, delivering answers without revealing their methodology. For an industry where every assumption must withstand intense scrutiny, this opacity is a non-starter.

This challenge is widely recognized across the financial world. Regulatory bodies like the SEC have put a sharp focus on AI explainability, concerned that opaque models could hide biases or critical errors. For investment committees tasked with allocating billions of dollars, an indefensible number is a liability. This has led to widespread hesitancy, with many firms limiting AI to peripheral tasks or finding that AI-generated outputs create more manual verification work than they save.

Industry experts note that without a clear audit trail, AI-driven decisions carry unacceptable reputational and financial risks. The fear is not just that the AI is wrong, but that no one can prove why it might be right. This forces teams into extended review cycles and manual rework, negating the speed AI is meant to provide.

From Opaque Answers to Auditable Insights

F2’s Audit Mode directly confronts this problem by fundamentally re-architecting how the AI delivers its analysis. At its heart is the “Databook,” a live, Excel-native system built directly from source documents. Instead of generating a static report or a final number, F2’s platform constructs a formula-rich workbook where every calculation is interconnected and transparent.

Audit Mode serves as the inspection layer for this Databook. When a user sees a number in an F2-generated report—be it a revenue forecast, a key performance indicator, or a risk assessment—they can instantly click into it. This action reveals the underlying formulas, the precedent cells used in the calculation, and a direct, highlighted link to the original source document, sheet, and cell where the data originated. This traceability is preserved even when the analysis is exported into a standard Excel file.

This granular transparency is designed to eliminate the need for manual, line-by-line verification. An analyst preparing for an investment committee meeting can not only present the final analysis but also instantly demonstrate the origin and calculation of any figure questioned by partners. This approach reflects the company's core philosophy of augmenting, not replacing, financial judgment.

“In private markets, moving fast doesn’t matter if you can’t defend the numbers behind your decision,” said Don Muir, CEO of F2, in the company’s announcement. “Speed isn’t about generating answers faster, it’s about trusting them. When the numbers are fully traceable, teams can invest with confidence. Audit Mode makes that possible.”

The ROI of Trust: Accelerating Deals and Mitigating Risk

The business implications of auditable AI extend far beyond technical elegance. By fostering trust, F2 aims to unlock tangible returns for investment firms. The platform claims to help firms evaluate deals up to 75% faster, a critical advantage in a competitive market. This acceleration comes not just from faster data processing, but from the radical reduction in time spent on manual validation and rework.

The market appears to be responding to this value proposition. Since its September 2025 spin-out from Arc Technologies, backed by prominent investors including NFX, Left Lane Capital, and Y Combinator, F2 has achieved 60x ARR growth and is now used by thousands of professionals across more than 100 enterprise firms. This rapid traction suggests a deep, unmet need for AI tools that align with the rigorous demands of financial workflows.

Investors like NFX have cited F2’s deep domain expertise and its focus on a “defensible vertical” as key reasons for their backing, noting that generic, horizontal AI platforms struggle to meet the specific needs of private markets. With Audit Mode, F2 strengthens its position by offering a solution that not only enhances efficiency but also serves as a powerful risk management tool, allowing firms to move with greater speed and conviction.

Augmenting the Analyst, Not Replacing Them

Rather than positioning AI as a replacement for human expertise, F2’s approach champions a model of human-AI collaboration. By automating the laborious and error-prone tasks of data extraction and reconciliation, the platform frees up financial analysts to focus on what they do best: applying strategic judgment, understanding market dynamics, and making nuanced decisions.

This “augmented analyst” model is rapidly gaining favor as the most realistic and powerful application of AI in finance. The goal is to elevate the role of the investment professional, turning them from data wranglers into strategic thinkers empowered with reliable, verifiable insights. The ability to trust the underlying data allows teams to spend less time checking formulas and more time debating the strategic merits of a deal.

With Audit Mode, F2 is making a clear statement that the future of financial AI is not about more powerful black boxes, but about building transparent systems that earn the trust of their users. By providing a clear, unbroken line of sight from a single number in an Excel sheet all the way back to its source, the platform offers a practical solution to one of the industry's most pressing technological challenges, potentially paving the way for broader and deeper integration of AI in critical investment decisions.
