Personio acquisition of Circula adds spend management to HR platform

Personio has acquired Circula, a German spend management platform, expanding its stated plan to combine HR, payroll and employee spending. The announcement says Circula’s DATEV connection and existing integration will stay in place. It does not disclose a purchase price, a legal review or a completion date.

The transaction is described as an acquisition between two companies that have worked together for several years. The supplied material identifies no regulator, filing, formal review or legal decision connected with the deal. It therefore provides no basis to characterise the transaction as approved, under investigation or subject to a particular regulatory stage.

What the announcement establishes

Personio, an HR and payroll platform founded in Munich in 2015, says it has acquired Circula. Personio’s stated aim is to bring HR, payroll and spend management together. The announcement presents the acquisition as a new phase in that product direction, while leaving the deal’s financial terms undisclosed.

Circula is described as a German platform for spend management, including expenses, corporate cards, accounts payable and tax-optimised benefits. More than 3,000 European mid-market businesses use its services, according to the supplied account. The companies’ joint work predates the acquisition, and hundreds of shared customers already use their integration.

What was in place before the acquisition?

Personio’s platform serves more than 16,000 companies employing 1.6 million people, according to the source material. Personio and Circula have served many of those customers together. Their existing connection synchronises employee data between Circula’s spending service and Personio’s HR platform, Circula co-founder Nikolai Skatchkov said.

The source describes each company as having developed compliance and tax expertise in its own area. Personio’s focus has been payroll, while Circula’s has been expenses and benefits. Skatchkov said a remaining challenge involved separate tax logic on the expense and payroll sides, which had been built by different companies.

What have the companies said will continue?

Skatchkov said the DATEV connection, the existing integration and Circula’s expertise would remain for customers after the acquisition. Personio chief executive Hanno Renner said spending on employees, including payroll, expenses and benefits, is intended to come together under one platform. These are the companies’ stated plans and commitments; the announcement does not document a completed technical merger.

Personio says expenses are intended to flow into payroll through payroll integrations and its native payroll engine. The material does not give implementation dates, describe migration arrangements or specify whether customer contracts and prices will change. No response from a regulator or other authority is included because none is named in the supplied reporting.

Which points still lack public detail?

The supplied account leaves the acquisition price, contractual terms and any regulatory process unspecified. It also does not say when customers will receive any new combined functionality. The companies’ statements describe product direction and continuity, rather than a timetable or a legal finding.

Circula had raised a €15 million Series A in 2025, while the acquisition announcement refers to broader investment in European software during 2026. The source lists selected funding rounds, but does not connect those rounds to the acquisition’s financing. Further company statements would be needed to clarify product rollout, customer arrangements and any formal legal steps.
