Adfin, the London-based fintech building an agentic money-movement platform, has raised $18m in a Series A round, the company said on Monday.
The round was led by Index Ventures, with participation from Visionaries Club and new investors Stéphane Kurgan, the former COO of King, and Andrey Khusid, founder of Miro. The investment brings Adfin's total funding to more than $30m in less than two years.
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.

Adfin pairs proprietary payment infrastructure with agentic AI workflows that decide how to chase, reconcile and clear invoices on behalf of small and mid-sized businesses.
The company cites research showing 63% of invoices sent by UK SMEs are paid late. Adfin says its own customers see only 9% of invoices paid late, a rate it describes as nearly seven times better than the UK SME average.
The platform now serves more than 1,500 businesses across the UK, from accounting and law firms to scaling businesses in professional services, trades and care.
Tom Pope, Adfin's co-founder and CEO, said in the announcement that the company is building toward end-to-end cashflow management.
“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,” Pope said.
“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.”
Pope added that the platform is designed to keep humans “firmly in control,” with auditable and trackable workflows for finance teams.
Liam McHugh, director at Steve Pye & Co, a Norwich-based accounting practice and Adfin customer, said in the announcement that the platform had delivered a roughly threefold reduction in his firm's late-payment rate, freeing staff from invoice chasing.
Julia André, partner at Index Ventures, said the firm is “tripling down” on the founders after backing them at pre-seed and seed.
“Index backs founders who have the rare ability to obsess over a problem and build category-defining businesses,” André said in the statement.
Co-founders Pope and Ciprian Diaconasu are both payments veterans. Pope spent more than a decade building payments infrastructure at Worldpay and at Tink, which Visa acquired for $2.2bn.
Diaconasu was the founding engineer at Mambu, the banking-platform business that reached a $5.3bn valuation and counts N26 and Tide among its customers.
Adfin said the Series A will fund the expansion of its product into end-to-end cashflow management, accelerated hiring across engineering and sales, and preparation for international expansion. The company did not disclose its post-money valuation, revenue or customer concentration by vertical.
