Round Treasury, a London-based startup developing an AI-driven finance automation platform for modern finance teams, has secured €5.1 million ($6 million) in Seed funding and introduced two new products: an Agentic Workflow Builder and Autonomous Payroll.
The round was led by Alstin Capital, with participation from Backed VC and Love Ventures. Notably, approximately 10% of Round’s existing customers also invested, together with angel investors like Paul Forster, the founder of Indeed. Existing investors, including Passion Capital and early backers of Monzo, Tide, and GoCardless, also doubled down on their investment.
“Everyone’s trying to build an AI CFO. Cursor didn’t get big by replacing the CTO. It got big by doing the work engineers didn’t want to do. We’re taking the same approach, but for finance,” said Pac O’Shea, co-founder of Round.
Founded in 2023 by Pac O’Shea and Hayyaan Ahmad, Round is an AI-powered finance automation platform used by some of Europe’s fastest-growing companies and unicorns, including Cleo and PostHog. The company combines financial infrastructure with AI and automation to streamline treasury, accounts payable, and payroll, eliminating the low-value, repetitive, and manual work that consumes much of finance teams’ time.
According to the company, despite billions invested in finance software, most finance teams remain the link between disconnected systems. They approve invoices in one platform, access bank portals to make payments, follow up with contractors via email, and perform reconciliations using spreadsheets. Each payment run, payroll cycle, and cash sweep depends on a human in the loop to carry out the steps, not to make decisions.
“We are building for the finance team of the future, one that understands the importance of automation to keep up with the pace of modern companies. AI tools are rapidly being deployed across the industry and finance teams do not need to be left behind,” said Hayyaan Ahmad, co-founder of Round.
The startup asserts that, unlike most AI in finance, which only provides copilots and chatbots that summarise data, answer questions, and recommend next steps, Round has developed both the intelligence and infrastructure. This includes wallets, payment rails, and treasury services that integrate seamlessly with a company’s existing banks and accounting software.
The company states that once the finance teams establish the rules, including approval thresholds, payment schedules, and cash minimums, Round executes automatically. Payments are processed, idle cash earns yield, payroll is funded and paid on time, and all activities are synchronised with the ERP.
Round is ISO 27001:2022 certified and works exclusively with FCA-regulated financial partners for its products. It notes that all transactions are logged with complete audit trails within the dashboard, giving finance teams full visibility and control across every movement of funds.
Round has also launched two new products, Agentic Workflow Builder and Autonomous Payroll.
Explaining how Agentic Workflow Builder works, Round said, “A CFO can describe the workflow they want automated in plain English and Round builds the workflow for their approval. Fund payroll early. Sweep idle cash into yield-bearing accounts. Chase contractors for missing invoices. Once approved, workflows run deterministically, 24/7, and ping you on Slack, WhatsApp, or email only when something needs attention. The kind of work that used to require a junior hire now runs in the background, continuously.”
The Agentic Workflow Builder is currently in early access, with select customers already testing workflows across treasury, payments, and finance operations. Companies interested in trying the feature can request access through the Round platform.
With Autonomous Payroll, the payroll runs itself. Round automatically retrieves payslips from users’ providers, prepares the payment run, routes approval to the appropriate person, funds from treasury, executes the payment, and confirms completion. This eliminates the need to log into multiple systems and perform manual funding.
Round stated that it introduced its first automated workflows less than a year ago. Since then, the platform has handled over €427.7 million ($500 million). In October 2024, the company announced the closure of its €1.9 million pre-Seed funding round led by Passion Capital.
With the fresh funding, the company plans to accelerate product development, expand the engineering and go-to-market teams, deepen integrations with banks and financial systems, and scale the platform’s infrastructure. It also plans to invest in community-led growth through finance-focused hackathons, hands-on workshops, and webinars to help teams discover and build automated workflows.
“Round’s workflow builder changes what’s possible. A finance team can describe work they do as steps, the system builds a workflow, they approve it, and it runs forever in the background. This funding lets us take that approach to every repetitive process in finance,” said Ahmad.
