Our take
9fin’s initial aim was to solve the problem of extracting data out of financial documents. It quickly turned to AI, where computer vision tools can be deployed to find key financial data point quickly and automatically.
Its AI tools learn to understand the complicated legal clauses in contracts, automating a lot of the manual work that's usually involve in this space. 9fin also has a team of journalists and analysts who product news and analysis that help make sense of complex situations. The result is an integrated platform that debt capital market professionals can use to make quicker and better investment decisions.
9fin is used by leading banks, hedge funds, and asset managers around the world. The company has seen significant investment, the most recent of which will support the scaling of its team and expansion of its product into new asset classes, as well as helping it to grow its presence in the US, Latin America, and Asia Pacific.

Company values
- Technology doesn't serve the business. Technology is the business: Technology and business are not independent; they are one and the same. We’ve met CEOs who don’t know what language their code is written in and CTOs who don’t know who the customers are. That’s not OK
- Talent trumps experience: We judge people by the quality of their ideas, not the duration of their employment. We’d rather work with people who have spent 12 months being awesome than those who have spent 3 years being average
- Don't know? Say so: Ignorance is only a weakness when you don’t admit it. We’ve seen lots of people waste hours of productivity because they were too afraid to ask for help
- Ship early and often: It’s impossible to design a truly awesome product without customer feedback
- Never settle: The product might have shipped, but it’s never perfect. If we can’t find ways to improve we just aren’t looking hard enough
- Diversity: We don’t discriminate. As well as being an end in itself, varied backgrounds and cultures bring new perspectives and stop group think
- Have an opinion: No decision is off limits to being challenged. Disagreement is healthy, it shows you care
- Beautiful simplicity: If it’s not easy to use, then it’s broken. Consumer applications relentlessly focus on the user with beautiful interfaces and snazzy graphics. There’s no reason why B2B can’t be just as good
- Make time for others: Everyone is busy. But taking 5-10 minutes out of your day to grab a coffee with a colleague who needs advice or help is not too much to ask
- Overcommunicate: Don’t leave people in the dark. It’s better to receive a 10 second note saying “Super busy, but I’ll get to it.” than radio silence
- Family & health come first: No customer or job matters more than family and your health
