Personio's Bold Move: Acquiring Circula to Revolutionize HR, Payroll, and Spend Management

### Personio Acquires Circula: A Game-Changer for European HR and Spend Management In a move that's set to redefine how European businesses manage their workforce and finances, HR tech unicorn Personio has announced its acquisition of Circula, a German spend management platform. This strategic acquisition aims to create the first European platform that seamlessly unites HR, payroll, and spend management – a first of its kind in the region. ### Why This Acquisition Matters For years, companies have struggled with fragmented systems: one for HR, another for payroll, and yet another for expenses. This disjointed approach leads to inefficiencies, data silos, and a lot of headaches for finance and HR teams. Personio's acquisition of Circula is a direct response to this pain point, promising a unified solution that could streamline operations for thousands of businesses. Hanno Renner, CEO and co-founder of Personio, put it simply: "Spend management is one of the capabilities our customers ask us for most, and it's complex to get right in Europe. Just as with payroll, rules change at every border. Over the past 9 years, Circula has already solved that complexity in an intuitive and powerful way." With Circula on board, Personio aims to bring everything a company spends on its people – payroll, expenses, and benefits – under one roof. ### The European Startup Incorporation Angle This acquisition also shines a light on the broader trend of European startup incorporation and consolidation. As European startups mature, they're increasingly looking to expand their offerings through strategic acquisitions. Personio, founded in Munich in 2015, is a prime example. It's now used by over 16,000 companies employing 1.6 million people. By acquiring Circula, Personio is not just adding a new feature; it's positioning itself as a comprehensive system that European businesses can run their entire workforce on. ### What Circula Brings to the Table Circula, founded in 2016, has built a strong reputation for simplifying spend management for mid-market businesses. With over 3,000 European mid-market businesses trusting Circula for expenses, corporate cards, accounts payable, and tax-optimized benefits, it's a valuable addition to Personio's suite. Nikolai Skatchkov, CEO and co-founder of Circula, explained the synergy: "Circula has solved syncing employee data between spend management and HR platform, and hundreds of joint customers already use that integration. The unsolved part is that the tax logic on the expense side and on the payroll side has always been built by two different companies. Joining forces with Personio today changes that." ### What This Means for Existing Customers For current Circula customers, it's business as usual – with a twist. The product will continue to be available and further developed as a standalone product for those not using Personio. For joint customers, the integration will deepen into a fully connected experience. Starting October 6, Circula will operate as "Circula by Personio," and the team will join Personio. ### The Bigger Picture: A Booming European HR Tech Market This acquisition comes amid a surge in investment in European HR and workforce management software. In 2026 alone, EU-Startups reported nearly €500 million in relevant funding rounds, including: - €200 million for French frontline workforce platform Skello - €129 million for Barcelona-based HRTech company Factorial - €37 million for Amsterdam-based workforce compliance platform WorkFlex - €30 million for Berlin-based spend-management company Moss The latter, Moss, is a particularly close comparison to Circula, offering corporate cards, invoices, and reimbursements for SMEs while expanding into AI-powered finance tools. ### A Unified Future Together, Personio and Circula aim to run all business spend – salary, benefits, expenses, and corporate cards – in one integrated platform. This vision aligns with the growing demand for streamlined, end-to-end solutions that save time and reduce complexity. As Renner noted, "With Circula joining Personio, everything a company spends on its people – payroll, expenses and benefits – comes together under one roof. That's a first in Europe, and a big step towards Personio being the system European businesses run their entire workforce on." For European startups and mid-market businesses, this acquisition signals a future where HR and finance are no longer separate silos but part of a cohesive strategy. And for Personio, it's a bold step towards becoming the operating system for European businesses. ### What's Next? The integration will continue to evolve, with deep DATEV integrations – a key part of both companies' strategies – being further developed to seamlessly integrate into a single solution. This will make life easier for tax advisors and their clients, a community both companies have actively supported. As the European tech ecosystem continues to mature, acquisitions like this one highlight the importance of strategic consolidation in driving innovation and efficiency. For Personio, it's a leap forward; for Circula, it's a new chapter; and for European businesses, it's a promising step towards simpler, smarter operations.
