9fin has raised £128.8m ($170m) in a series C funding round at a £985.1m ($1.3bn) valuation to accelerate its AI platform for global debt markets. The London‑headquartered fintech startup will use the capital to expand its proprietary dataset, deepen AI capabilities and push further into the United States; the round was led by HarbourVest and included CPP Investments alongside earlier backers Redalpine, Highland Europe, Spark Capital and Seedcamp.
Why it matters
Debt capital markets are the largest asset class in the world — estimated at around $145 trillion — yet much of the market still relies on fragmented, manually extracted information. Firms that can surface reliable, structured data quickly gain an edge in sourcing and executing loans, bonds and private credit deals. 9fin says more than 300 banks, asset managers, law firms and advisory firms already use its platform, and the new funding comes after multiple years of reported 100% ARR growth and high client retention.
For market participants and fintech investors, the raise highlights continued appetite for tools that combine deep datasets with workflow automation rather than single-point analytics.
Inside the product
9fin centralises documents and market intelligence — much of it trapped in data rooms, emails and PDFs — and applies machine learning to power deal discovery, risk analysis and monitoring within a single interface. The product is positioned as an AI-native platform for credit professionals, aiming to reduce hours of manual research and to help clients identify opportunities and manage mandates faster.
Key capabilities the company plans to scale with this round include expanded proprietary data coverage across loan, bond and private credit instruments and upgraded AI models embedded into day-to-day workflows. The company also emphasises cross-asset coverage and faster US expansion as priority uses for the fresh capital.
Who are the investors?
The series C was led by HarbourVest, a global private markets firm that reported £113.7bn ($150bn) of assets under management as of 31 December 2025. CPP Investments participated in the round; the Canadian pension fund was already a 9fin client before converting that relationship into an investment, signalling commercial validation of the platform.
Earlier investors Redalpine, Highland Europe, Spark Capital and Seedcamp also took part. With this round, 9fin has raised more than £189.4m ($250m) to date.
In the announcement, Michael Guiness, Principal at HarbourVest Partners, said:
Debt markets are undergoing a profound transformation as AI reshapes how financial professionals work. 9fin has built a powerful platform combining proprietary data with AI-driven workflows - exactly what we're looking for in next generation market leaders. We're excited to support the company as it scales globally.
In the announcement, Houda Hamdouch, Principal at HarbourVest Partners, said:
We've followed 9fin closely over several years and have been consistently impressed by the team's execution and vision. The company's continued expansion across the credit ecosystem — from banks and asset managers to private credit platforms — underscores the strength of its product.

Founder perspective
In the announcement, Steven Hunter, CEO & Co-founder of 9fin, said:
AI will redefine the credit markets, but only if it's powered by proprietary data and embedded into how professionals actually work. That's exactly what we've built at 9fin. We've scaled our product rapidly across geographies and asset classes to provide clients with unmatched breadth and depth of data in an AI-native platform. Our ultimate goal is to be the only platform credit professionals ever need. This capital gets us there even faster.
Hunter co-founded 9fin with Hussam EL‑Sheikh; the company maintains offices in London, New York, Hong Kong and Belfast, with teams active across Latin America and Asia.
The bigger picture
The deal underscores a broader shift in fixed income and credit markets toward platforms that combine specialised datasets with automation. As loan, bond and private credit markets converge, tools that reduce search friction and speed decision-making are becoming commercially valuable. The presence of institutional investors such as HarbourVest and CPP Investments also reflects continuing interest from fintech investors in infrastructure plays rather than front-end consumer products.
For competitors and incumbents, the challenge is twofold: matching 9fin’s dataset breadth and embedding models into workflows used by credit analysts and deal teams.
This funding round is another marker of UK fintechs’ ability to attract large, late-stage capital while expanding internationally. As 9fin pushes deeper into the US and scales AI-driven data coverage, the result will be watched closely by investors and credit market participants across Europe and beyond.
