Adfin raises $18m Series A to expand revenue collection platform

By Aarav Garg

Adfin has raised $18 million in Series A funding to expand its AI-driven revenue collection and finance automation platform, taking total investment in the company to more than $30 million in under two years.

The round was led by Index Ventures, with participation from existing backer Visionaries Club. Adfin said the new capital will support its shift beyond payment collection into broader finance workflows, with a focus on automating routine money movement tasks while keeping human oversight in place.

Adfin has built infrastructure aimed at helping businesses get paid faster and manage cash flow more efficiently. The company said its platform has already cut the time needed to sign direct debit mandates and improved payment collection through features such as fallback payment links, daily settlement and accounting integrations.

According to the company, customers using its system now see a much lower share of invoices paid late than the UK average. That performance has helped position Adfin within a wider FinTech trend of using modern payments infrastructure and automation to improve working capital for small and mid-sized businesses.

The company is now expanding into what it describes as agentic finance, where AI tools would support more of the manual work involved in credit control, collections and related finance operations. Early use cases are expected to focus on automated reminder sequences, late fee calculations and customer communications, while leaving key decisions under human control.

Adfin said the broader goal is to make money movement more automated, auditable and efficient across the finance function. The latest funding will be used to accelerate product development as the company looks to extend its platform beyond collections and into more of the operational finance stack.
