About 9fin

9fin is the AI platform powering global debt markets—the world’s largest asset class at over $145 trillion. Debt markets are vast, global, and mission‑critical, yet still run on fragmented data, PDFs, and manual workflows. 9fin replaces this broken infrastructure with a single platform that centralises proprietary credit data, deep analysis, and high‑value workflows across global markets.

Today, 9fin powers teams at 300+ blue‑chip institutions worldwide, including global banks, asset managers, private equity firms, law firms, and advisors. The business is scaling at exceptional speed, with rapid expansion in the US and best‑in‑class retention driven by deep workflow adoption.

We’re at a defining inflection point. With proven product‑market fit and strong, global market pull, 9fin is accelerating toward becoming the category‑defining platform for debt markets worldwide.
