Adfin Secures $18M Series A to Automate SME Payments with Agentic AI

Adfin has closed an $18 million Series A led by Index Ventures with participation from Visionaries Club, bringing total funding to $30 million. The London startup applies agentic AI and a proprietary payment infrastructure to confront chronic late payments that squeeze small and medium enterprises.

Addressing the Late Payment Challenge for SMEs

Late payments remain a systemic drag on SME cash flow. In the UK 63% of businesses report being affected by overdue invoices, creating working capital stress and administrative burden. Traditional collection methods are manual, slow, and costly, leaving many firms reactive rather than pro‑active.

Adfin’s Agentic AI Solution

Adfin combines agentic AI with a payments rail it controls to automate receivables. Agentic AI means autonomous software agents that assess invoices, select the optimal collection pathway, execute actions across banking and accounting systems, and escalate to humans when needed. The company reports reducing late payments to 9% for customers, a marked improvement versus the broader market.

Strategic Growth and Future Vision

Proceeds will fund product development toward end-to-end cash flow management, scaling engineering teams, and international expansion. “Our agentic finance platform will take routine payment decisions off teams and leave strategic work to humans,” said CEO Tom Pope. The focus is both operational automation and widening the product to cover forecasting and liquidity orchestration.

The Broader Impact on AI Fintech

Adfin’s approach highlights how autonomous AI models integrated with payment rails can rework financial workflows, reduce operational cost, and unlock predictable cash flow for SMEs. For investors and fintech founders, the round signals growing conviction that agentic systems, when paired with control over infrastructure, offer a replicable path to scale in real-world finance use cases.

Adfin’s next phase will be a test case for whether agentic AI can move from point solutions to platform-level control of financial operations across markets.
