Round raises $6m for journey to autonomous treasury

​London-based fintech Round has raised $6 million in seed funding to expand its AI-powered finance automation platform, as investor interest in autonomous finance operations continues to accelerate.

Founded in 2023 by Pac O’Shea and Hayyaan Ahmad, Round develops software designed to automate treasury management, payments, payroll, FX and accounts payable processes for finance teams at high-growth companies. Customers include Cleo and PostHog.

​The funding round was led by Munich-based Alstin Capital, with participation from Backed VC and Love Ventures. Existing investors including Passion Capital also reinvested, while approximately 10% of Round’s customers joined the round alongside angel investors including Indeed co-founder Paul Forster.

The company said the new funding will be used to scale its financial infrastructure and accelerate product development, including the launch of two new tools: an Agentic Workflow Builder and an Autonomous Payroll platform.

Round’s platform sits between banks, ERP systems and payment rails, using AI and workflow automation to reduce manual finance tasks including invoice approvals, payment execution and payroll funding. The company said it has already processed more than $500 million in transactions since launch.

Chief executive Pac O’Shea said the company was focused on automating operational finance work rather than replacing finance teams altogether.

“Everyone’s trying to build an AI CFO,” O’Shea said in a statement. “We’re taking the same approach, but for finance.”

The company said many finance teams continue to rely on fragmented systems and manual workflows despite growing investment in finance software. Round argues that embedded AI agents and workflow orchestration will become increasingly important as finance functions look to improve efficiency without expanding headcount.

Alstin Capital partner Andreas Schenk said Round represented “a fundamentally new approach to finance operations”, describing the company as an orchestration layer connecting banking, treasury and payment infrastructure in real time.

The funding comes amid a broader wave of investment into AI-native finance and treasury platforms, as startups increasingly target manual operational processes across corporate finance, accounting and payments. Investors are betting that agentic AI systems capable of executing workflows — rather than simply generating insights — could significantly reshape finance operations over the next decade.
