The news
Personio acquires Circula: on October 6, 2026, Munich-based HR and payroll software company Personio announced it is acquiring Circula, a Berlin spend management platform, to bring payroll, expenses and employee benefits onto one system for midsize companies. Financial terms were not disclosed.
Circula sells software for employee expenses, corporate cards, accounts payable and tax-optimized benefits. According to Lincoln International, which advised Circula on the sale, the company was founded in 2017 and serves more than 3,000 European midsize businesses with about 250,000 users.
Personio, founded in 2015, sells HR and payroll software to organizations with roughly 25 to 5,000 employees. Lincoln International said Personio serves more than 16,000 companies employing 1.6 million people and has more than 1,500 staff across six European offices.
The two companies already worked together. Tech.eu reported that many Personio customers already used both products through an existing partnership. After the deal, Circula will operate as a separately branded product, Circula by Personio, according to Tech.eu.
Personio co-founder and CEO Hanno Renner said, as reported by Tech.eu, that with Circula joining, everything a company spends on its people comes together. Circula co-founder and CEO Nikolai Skatchkov stressed continuity for customers in the German market, telling Tech.eu that its integration with DATEV, the accounting software widely used by German tax advisers, will stay.

Why CEOs should care
For CFOs and HR leaders at midsize companies, this is another step toward one vendor handling everything a company spends on its people: salaries, benefits, reimbursements and corporate cards. A single system can mean fewer reconciliations between payroll and expenses and cleaner data for audits. It also means more leverage for the vendor at renewal. Ask whether bundled pricing actually beats your current mix of tools over a three-year term.
Current Circula customers who do not use Personio should ask whether Circula will stay available on its own, for how long, and whether integrations with rival HR systems will keep being maintained, and get the answers in writing. Personio customers should ask whether expense and card features will be included in existing plans or sold as add-ons, and when deeper integration will ship.
For U.S. companies with European operations, the deal matters because HR and payroll in Europe often run on regional vendors. If you use Personio or Circula for European staff, check how the combination affects data residency, card programs and connections to your U.S. finance stack.
The bigger picture
Back-office software is consolidating. HR platforms have added payroll, then benefits, and are now moving into spend management, a market long served by separate expense and corporate card providers. In the United States, companies such as Rippling have pushed a similar all-in-one approach. For midsize firms, the trade-off is convenience and shared data against dependence on a single supplier for critical money flows.
What’s next
Watch for Personio to publish pricing and packaging for Circula by Personio, a timeline for deeper product integration, and whether it pursues further acquisitions to fill gaps in its suite.
What “Fact-checked” means
Fact-checking means testing a story’s facts against the evidence before it is published. This story went through at least two separate checks before this version was published.
- What we checked
- Its names, figures, dates, job titles, quotes and who said what were checked against the story’s sources, including its main source where it could be opened. The headline was checked for accuracy and overstatement.
- How
- A first check reviewed the whole story. If it passed, a second, skeptical check went back to the sources to look for mistakes in the most important facts. If a check flagged the story, it was edited to fix the problems found, and a separate re-check then reviewed the whole story again.
- Who
- The checks are made by our newsroom, as steps kept separate from the writing, under rules set by our editor, Hussein Mukhtar. A story the checks still flag is held for the editor, who decides whether it is fixed, published or dropped.
- If something is wrong
- “Fact-checked” does not mean error-free. If a material error is found after publication, we correct the story and add a note saying what changed. Report an error
