Round Treasury, a London-based startup building AI tools for finance teams, has raised €5.1 mn in Seed funding and launched two new products: Agentic Workflow Builder and Autonomous Payroll.
Alstin Capital led the round, with Backed VC and Love Ventures participating. Around 10% of existing customers also invested, alongside angel backers including Indeed founder Paul Forster.
Existing investors, including Passion Capital and early supporters of Monzo, Tide and GoCardless, increased their stakes.
Founded in 2023 by Pac O’Shea and Hayyaan Ahmad, Round combines financial infrastructure with AI to automate treasury, accounts payable and payroll. Customers include companies such as Cleo and PostHog.
Co-founder Pac O’Shea said the company is not trying to replace finance leaders with AI. He said the focus sits on removing repetitive work. He compared the approach to developer tools which gained traction by handling tasks engineers avoided rather than replacing them.
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
Pac O’Shea, co-founder of Round
Finance teams still operate across disconnected systems. They approve invoices in one platform, log into bank portals to make payments, follow up with contractors through email and reconcile accounts in spreadsheets. Each payroll run or payment cycle still depends on someone executing tasks manually.
Round positions itself as an execution layer rather than a reporting tool. Instead of chatbots or copilots which summarise data and suggest actions, the platform integrates wallets, payment rails and treasury services directly with banks and accounting systems.
Once finance teams define rules such as approval thresholds, payment schedules and cash limits, the system runs automatically.
Payments go through, idle cash moves into yield accounts, payroll is funded and executed, and records sync with ERP systems.
The platform is ISO 27001:2022 certified and works with FCA-regulated partners. All transactions are logged with full audit trails, giving teams visibility across fund movements.
The new Agentic Workflow Builder allows finance teams to describe workflows in plain English. The system builds them for approval, then executes them continuously.
Tasks such as funding payroll, managing cash or chasing invoices run in the background and only trigger alerts when needed. The feature is currently in early access.
Autonomous Payroll handles payroll end to end. The system retrieves payslips, prepares payments, routes approvals, funds payroll and confirms execution without requiring manual intervention across multiple systems.
Round launched its first automated workflows less than a year ago. Since then, the platform has processed more than €427.7 mn, equivalent to about $500 mn.
The company will use the funding to accelerate product development, expand engineering and go-to-market teams, deepen integrations with financial systems and scale infrastructure.
It also plans to invest in community-driven growth through hackathons, workshops and events focused on finance automation.
