Round Raises $6M to Launch Autonomous Payroll and Treasury Automation Tools

London-based fintech startup Round announced on April 10, 2026, that it has closed $6 million in seed funding to expand its AI-powered finance automation platform. The funding coincides with the launch of two new products: an Autonomous Payroll module and an Agentic Workflow Builder.

The platform is designed to automate treasury, payments, and payroll for modern finance teams, aiming to replace manual operational work with end-to-end automation. Since its launch, Round has processed more than $500 million in transactions and is used by several of Europe’s fastest-growing companies and unicorns, including PostHog and Cleo.

Investment and Strategic Backing

The seed round was led by Alstin Capital, a Munich-based generalist early-stage venture capital firm specializing in B2B software. Other participating investors include Love Ventures and Backed VC.

Existing investors, including Passion Capital—the early backer of GoCardless, Tide, and Monzo—also increased their investment in the company. The round was further supported by angel investors, including Paul Forster, the co-founder of Indeed.

A notable aspect of the funding round was the participation of Round’s own client base, with approximately 10% of existing customers choosing to co-invest in the company.

Addressing Manual Finance Workflows

Round focuses on the operational gaps that persist despite the prevalence of finance software. Many finance teams currently serve as the manual connective tissue between disconnected systems, performing tasks such as logging into bank portals to execute payments, approving invoices in separate tools, and chasing contractors over email.

The platform addresses these inefficiencies by combining financial infrastructure with AI. It integrates with existing accounting systems and banks, allowing finance teams to define specific rules for payment schedules, cash management, and approvals. Once these rules are established, the system executes the processes automatically and synchronizes the data with enterprise resource planning (ERP) systems.

New Automation Tools

The newly released Autonomous Payroll module is designed to streamline the payroll cycle. The tool pulls payslips from a provider, prepares the payroll run, and routes it for execution.

The Agentic Workflow Builder focuses on reducing manual workloads by automating repetitive operational steps. These are tasks that typically require a human to execute a sequence of actions—such as cash sweeps or payment runs—rather than make a strategic decision.

Product Philosophy

Round’s approach differs from other AI initiatives that seek to create an AI-driven CFO. Instead, the company focuses on automating the tedious, repetitive tasks that finance professionals typically handle manually.

Everyone’s trying to build an AI CFO. Cursor didn’t get big by replacing the CTO. It got big by doing the work which engineers didn’t want to do. We’re taking the same approach, but for finance

Pac O’Shea, Co-Founder of Round

By focusing on the execution of operational steps rather than the replacement of finance leadership, Round aims to reduce the time finance teams spend on non-strategic work.
