London fintech Adfin has raised $18 million in Series A funding to expand its agentic finance platform for small and mid-sized businesses. The round, announced on 12 May 2026, was led by Index Ventures and brings total funding to more than $30 million in less than two years.

Visionaries Club returned as an existing investor. Two notable new names also joined the round: Stéphane Kurgan, former Chief Operating Officer of mobile gaming company King, and Andrey Khusid, founder of collaborative whiteboard platform Miro.

Adfin pairs proprietary payment infrastructure with AI agents that decide how to chase, reconcile, and clear invoices on behalf of finance teams.

## Who founded Adfin?

Adfin was founded in 2024 by Tom Pope (CEO) and Ciprian Diaconasu (CTO). Both are payments veterans. Pope spent more than a decade building payments infrastructure at Worldpay and at Tink, the open banking platform acquired by Visa for $2.2 billion. Diaconasu was the founding engineer at Mambu, the cloud banking platform that reached a $5.3 billion valuation and counts N26 and Tide among its customers.

The company is headquartered in London, with engineering teams in the UK and Romania.

## How does Adfin's product work?

Adfin's platform automates the workflows finance teams use to get paid, manage cashflow, and reconcile invoices. Specialised AI agents handle tasks such as sending payment reminders, processing direct debits, and matching incoming payments against invoices.

According to research from FreeAgent cited by the company, 63% of invoices sent by UK SMEs are paid late. Adfin says its own customers see late-payment rates of just 9%, nearly seven times lower than the UK average. The platform now serves more than 1,500 businesses across accounting, law, professional services, trades, and care sectors.

Tom Pope, co-founder and CEO of Adfin, said in the announcement: "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. 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."

## What will the funding be used for?

The Series A capital will fund three priorities. First, the company plans to expand its product into end-to-end cashflow management, moving beyond invoice payments into broader money movement. Second, Adfin is stepping up hiring across engineering and sales. Third, the company is preparing for international expansion beyond its UK base.

Adfin did not disclose its post-money valuation, revenue, or customer concentration by sector.

The announcement comes weeks after Adfin was named the third fastest-growing technology company in Europe, and the fastest-growing UK company, by Scaling Europe.

Julia André, partner at Index Ventures, said the firm is "tripling down" on the founders after backing them at pre-seed and seed. Adfin has now raised three rounds from Index in under two years, alongside its €8 million seed in February 2025.

## What this means for UK founders

Two signals stand out for UK founders watching this round. The first is the bet on agentic AI applied to a workflow most businesses still handle manually. Late payments remain one of the largest cashflow problems for UK SMEs, and Adfin's claim of a seven-fold improvement against the national average is the kind of concrete metric investors look for at Series A. If you are building in the AI applications layer, the message is clear: vertical depth and a measurable outcome beat horizontal positioning.

The second signal is the investor mix. Operator-investors like Stéphane Kurgan and Andrey Khusid bring different value than institutional capital alone, and their participation often correlates with future hiring and operational support. For UK founders building category-defining fintech infrastructure, this round shows London still attracts world-class capital across both venture firms and operator networks.
