Index Ventures backed-Adfin raises €15.3 million to help businesses automate revenue collection with AI

Adfin, a London-based FinTech startup building the agentic money movement platform for businesses, has raised €15.3 million ($18 million) in Series A funding to expand its product into end-to-end cashflow management, step up hiring across engineering and sales, and prepare for international expansion.

The round was led by Index Ventures, with participation from Visionaries Club and new investors Stéphane Kurgan (former COO of King) and Andrey Khusid (founder of Miro). The investment brings Adfin’s total funding to more than €25.5 million ($30 million) in less than two years.

Tom Pope, Adfin co-founder and CEO, said, “Adfin is building the agentic finance platform for money movement: automating the workflows finance teams use to get paid, manage their money, and, in time, much more. And we’re doing it the way our customers keep telling us they want: safe, auditable, trackable, with humans firmly in control. By owning both the underlying financial infrastructure and the agentic workflows on top, we’ll let finance teams deploy agents in a way nobody else can.

“Why does this matter? If you’re getting paid faster and optimising how you manage cash, you’re building a better business. Money movement isn’t admin, it’s the bloodstream of every company. We believe this so strongly that we’ve rewritten our mission around it: Adfin exists to help the world build better businesses.”

Founded in 2024 by Pope and Ciprian Diaconasu, Adfin claims to be the first platform designed from the ground up for the specific demands of invoice payments. It enables businesses to get paid faster and at lower cost, across all payment methods and communication channels. 

According to the company, in the UK alone, almost two-thirds (63%) of invoices sent by SMEs are paid late. This strains working capital, slows growth, and puts jobs at risk. 

Adfin claims to give SMEs the tools to get paid on time. It combines proprietary new payment infrastructure with agentic AI to decide the best course of action for each client and automate the tedious tasks that were preventing businesses from doing what they do best: managing client relationships. 

The company reports that this infrastructure has already achieved “outstanding” results for Adfin customers. Currently, only 9% of their invoices are paid late, which is nearly seven times better than the 63% rate for the UK overall, says Adfin. It currently serves over 1,500 businesses across the UK, including accounting and law firms, as well as growing companies in professional services, trades, and care.

Julia André, Partner at Index Ventures, said, “Index backs founders who have the rare ability to obsess over a problem and build category-defining businesses. We see that same pattern in Tom and Ciprian. We backed them at pre-seed and seed, and we’re tripling down, because their results speak for themselves.”

With this funding, Adfin plans to expand the Adfin product into end-to-end cashflow management, step up hiring across engineering and sales, and prepare for international expansion.
