Adfin has raised an $18 million Series A, bringing total investment in the company to more than $30 million in under two years. Index Ventures led the round again, with Visionaries Club participating alongside new investors Stéphane Kurgan and Miro founder Andrey Khusid.

The funding itself is notable, but the bigger story is how Adfin sees the future of finance operations. The company started with a narrow but painful problem: businesses getting paid late. According to Adfin, 63% of businesses are paid late, which still feels absurd when invoices are tied to legally binding agreements. Yet most finance teams still spend hours chasing payments, retrying collections, sending reminders, and fixing disconnected systems manually.

That operational mess became the foundation for Adfin’s product strategy.

Infrastructure First, AI Second

Adfin’s first focus was not AI agents or workflow automation. It was payments infrastructure. The company built systems aimed at making money move faster and with fewer points of failure. That includes direct debit flows, retry logic, integrations with accounting platforms, and faster settlement timing.

Some of the improvements are fairly simple, which is probably why they work. Adfin says mandate requests are signed three times faster because requests come from a customer’s own email address instead of a generic mailbox. Failed direct debits trigger alternative payment links immediately rather than waiting for another collection attempt. Customers also receive daily settlement instead of weekly.

Those operational tweaks appear to be producing meaningful results. Adfin says its customers now see only 9% of invoices paid late compared to the broader UK figure of 63%.

For finance teams, that difference is not cosmetic. Cash flow issues usually begin with operational friction. A delayed invoice here, a failed collection there, and suddenly teams are spending more time managing processes than managing the business itself.

Where Adfin Is Heading Next

The company now wants to expand beyond collections into broader finance automation. Adfin describes its vision as “money that moves itself,” combining payments infrastructure with AI-driven workflows across finance operations.

The interesting part is the tone of the announcement. Unlike many AI-heavy fintech pitches right now, Adfin repeatedly stresses human control. Their argument is not that finance teams disappear. It is that repetitive operational work disappears while people keep ownership over judgement calls and exceptions.

That feels far more realistic than the fully autonomous finance narrative floating around the industry.

The first example will be Adfin’s upcoming “customer agents,” designed for credit control workflows. The agents will automate tasks like reminder sequences and late fee calculations while finance teams decide how much automation they actually want. That balance between automation and oversight will probably matter more than raw AI capability for most finance leaders.

Key Takeaways for Fintech Startups

A few themes stand out from Adfin’s announcement.

• Infrastructure still matters more than flashy AI layers.
  
  
• Finance teams want automation without losing visibility or control.
  
  
• Small workflow fixes can have massive cash flow impact over time.
  
  
• Late payments remain one of the least solved operational problems in business finance.
  
  
• Fintech companies increasingly win by combining infrastructure with workflow automation instead of treating them separately.
