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.

A note from the hiring manager "Now is an exciting time to join 9fin. In 2020 we had a handful of clients and an untested product, but thanks to the efforts of the incredible engineering and content teams, we’ve made huge strides in the last four years. We now find ourselves with a game-changing tech platform and huge opportunities across the world’s biggest financial institutions. We need driven and ambitious sales and account management professionals to help us break into new markets, launch brand new product lines and unlock 9fin’s massive potential.
