London-based fintech startup Adfin has secured $18 million in Series A funding as it looks to reshape how businesses manage money movement and cashflow operations.
The round was led by Index Ventures, with backing from Visionaries Club, alongside new investors Stéphane Kurgan, former COO of King, and Andrey Khusid, founder of Miro. With this latest raise, Adfin’s total funding has crossed $30 million in under two years.
The startup was founded in 2024 by payments veterans Tom Pope and Ciprian Diaconasu. Pope previously spent more than a decade developing payment systems at Worldpay and Tink, which was acquired by Visa for $2.2 billion. Meanwhile, Diaconasu was the founding engineer at Mambu, the cloud banking platform that reached a valuation of $5.3 billion and powers fintech companies including N26 and Tide.
“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,” says Pope.
It was built around a problem that continues to hurt small and medium-sized businesses: delayed payments. In the UK, nearly 63% of invoices issued by SMEs are paid late, creating pressure on cashflow and limiting growth opportunities. Adfin tackles this challenge through its automated finance platform, combining proprietary payment infrastructure with intelligent workflow automation.
Its system determines the best follow-up actions for unpaid invoices while reducing the manual administrative work that finance teams usually handle. Businesses using the platform currently report only 9% of invoices being paid late, a significant improvement compared to the wider UK average.
Adfin operates in a crowded fintech market alongside companies such as GoCardless, Billtrust, and other invoice automation and accounts receivable platforms focused on helping businesses manage payments and collections.
However, the fintech combines its own payment infrastructure with automated workflow technology, allowing finance teams to automate collections, payment follow-ups, and cashflow management from a single platform. It is touted to give businesses more control, visibility, and automation across the full money movement cycle while still keeping human oversight in place.
The startup already serves more than 1,500 businesses across the UK, including accounting firms, legal practices, care providers, trades businesses, and professional services companies.
“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,” notes Julia André, partner at Index Ventures.
With fresh capital now in place, Adfin plans to expand beyond invoice collection into full end-to-end cashflow management. The company is also increasing hiring across engineering and sales while preparing for international expansion, positioning itself to become a broader financial operations platform for businesses beyond the UK.
