Personio acquires Circula and keeps spend standalone
Personio has acquired Circula and will run it as Circula by Personio. No purchase price was disclosed, and customers outside Personio keep a standalone product.
Personio's October 6, 2026 acquisition of Circula inverts a pattern I have tracked in corporate spend: the card company usually stays outside the human resources (HR) system. Ramp is still priced as its own network. In Munich the buyer is the HR platform, and Personio did not state a purchase price. From that date the business trades as Circula by Personio. Customers that do not use Personio are promised a standalone product.
The missing price is the point. Personio is making permanent a partnership that already reached many of its customers, and it wants payroll, expenses and benefits from one vendor. Hanno Renner, chief executive and co-founder of Personio, called that combination a first in Europe.
What Munich put on the record
The October 6 release says Personio is joining forces with Circula, which it calls one of Europe's leading spend management platforms. More than 3,000 European mid-market businesses use Circula for expenses, corporate cards, accounts payable and tax-optimised benefits. The same note cites over 3,000 companies and 250,000 users. Circula was founded in Berlin in 2017, and the team joins Personio. Tech.eu's same-day account adds no consideration, no revenue and no valuation.
Personio, founded in Munich in 2015, says it is used by more than 16,000 companies employing 1.6 million people. It lists six offices in Europe, more than 1,500 employees, and organisations of 25 to 5,000 employees. The two firms had already served many of those customers together. Hundreds of joint customers sync employee data between spend management and HR. Expenses are meant to reach payroll through existing integrations and through Personio's native payroll engine.
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.
Nikolai Skatchkov, chief executive and co-founder of Circula, said that in the release. DATEV stays, he said, the existing integration stays, and the expertise Circula built stays. What changes is that HR, spend, and now payroll "are designed to be one." Renner said customers ask for spend management because rules change at every border, as they do in payroll, and he credited Circula with nine years on that problem.
Peers with a number, and one customer
EU-Startups, that morning, called Moss the close German comparison: corporate cards, invoices and reimbursements for small and mid-sized firms, and it quoted no other spend vendor. Industry Spread reported that Moss crossed a €1 billion valuation on August 5, 2026, on a Portage-led Series C whose size Moss did not disclose. Moss published the mark and not the cheque. Personio published neither.
Ramp raised a $750 million Series F at a $44 billion valuation on June 4, 2026, the cost of staying independent when payroll sits elsewhere. Personio is treating cross-border tax rules as the reason to own Circula rather than leave spend management next door. Stuut raised a $52.5 million Series B led by Insight Partners, it said on October 7, 2026, and sells a tool that posts cash into the enterprise resource planning (ERP) system. Accounts payable is on Circula's list.
DATEV is the pipe that has to work
Both companies say they have a community of hundreds of tax advisors and features for those advisors to work with clients. Data already moves into DATEV's payroll and accounting systems, and the release says the links will in time "seamlessly integrate into a single solution." The October 6 text names no supervisor and no approval still open.
Everphone is the customer speaking. Veronika von Heise-Rotenburg, chief financial officer of Everphone, said Personio and Circula have run side by side there for more than six years. "Payroll, cost centres and approvers were synced from day one, so two products never felt like two systems," she said.
The release pulls in two directions. Renner describes "everything a company spends on its people." A later line aims at salary, benefits, expenses and corporate cards together. Circula's description also lists travel costs and accounts payable. A supplier invoice is not a people cost, and the text never says whether that module stays whole once the employee record is the centre.
What happens next is a retention test. Joint customers are promised a fully connected experience. Circula customers off Personio are told the product "will continue to be available and further developed as a standalone product." If that sentence holds, Personio bought distribution without a forced migration. If expense-tax logic is kept up only beside the native payroll engine and a single DATEV feed, standalone becomes a path onto Personio. I expect the answer in product notes, not in a price. Until a figure exists, read the deal as reach into more than 16,000 HR customers, not as a mark on 250,000 users.
