Adfin raises $18m Series A from Index Ventures for agentic business finance

At a glance:

• Adfin secures $18m Series A led by Index Ventures, boosting total funding to over $30m in 18 months
• The London fintech claims its agentic AI platform reduces SME invoice late payments to 9% (7x better than UK average)
• Now serves 1,500+ businesses across accounting, law, and professional services sectors

Funding momentum and investor confidence

Adfin's $18m Series A round marks a significant acceleration in its growth trajectory. Led by Index Ventures with participation from Visionaries Club and new investors Stéphane Kurgan (ex-King COO) and Andrey Khusid (Miro founder), the investment brings the company's total funding to over $30m in less than two years. This rapid capital influx follows Adfin's recognition as Europe's third fastest-growing tech company and the fastest-growing UK tech firm by Scaling Europe. The funding surge coincides with the company's expansion into end-to-end cashflow management, a strategic pivot that positions it to challenge traditional financial infrastructure providers.

The company's agentic AI workflows represent a novel approach to business finance. By combining proprietary payment infrastructure with autonomous decision-making systems, Adfin automates invoice reconciliation, payment chasing, and cashflow optimization for SMEs. This system reportedly reduces late payments from the UK SME average of 63% to just 9% among its clients. The platform's dual-layer architecture—handling both financial rails and intelligent workflows—creates a competitive edge in a market where 63% of invoices remain unpaid on time according to industry research.

Customer impact and market validation

Adfin's technology has demonstrated measurable ROI for its clientele. Tom Pope, co-founder and CEO, highlights that the platform maintains human oversight while automating complex financial workflows. This balance is critical for SMEs that require both efficiency and auditability. Liam McHugh of Steve Pye & Co accounting practice reported a threefold reduction in late payments after adopting Adfin, freeing staff time previously spent on manual invoice management. The platform's success across diverse sectors—from legal firms to professional services—suggests broad applicability beyond traditional finance verticals.

Founders' expertise and strategic vision

The leadership team brings deep payments industry experience. Tom Pope spent over a decade building payment infrastructure at Worldpay and Tink (acquired by Visa for $2.2bn), while Ciprian Diaconasu founded Mambu, a banking platform valuated at $5.3bn. Their combined background in scalable financial systems informs Adfin's technical approach. Index Ventures' Julia André emphasized the founders' problem-solving focus, stating they back entrepreneurs who "build category-defining businesses." This track record of building high-value fintech solutions positions Adfin to potentially reshape SME financial operations.

Expansion plans and future challenges

The Series A funding will accelerate product development toward full cashflow management capabilities. While Adfin hasn't disclosed post-money valuation or revenue figures, the company plans to expand its engineering and sales teams. International expansion is also on the horizon, though specific regions remain undisclosed. Challenges may include regulatory hurdles in new markets and competition from established payment processors. The company's agentic AI differentiation will need to prove sustainable against potential incumbents entering the space.

Industry implications

Adfin's approach could disrupt traditional SME finance models. By automating workflows previously handled by human finance teams, the platform reduces operational costs while improving payment efficiency. This aligns with broader fintech trends toward AI-driven financial services. However, the success of agentic systems in finance remains unproven at scale. Competitors may attempt to replicate Adfin's model, potentially leading to consolidation in the SME payment space. The company's focus on UK markets provides a testing ground before broader European expansion.
