Just three months after raising $40 million in a Series B funding, German HR and recruiting platform Personio is announcing that it has acquired Rollbox, the Spanish startup that offers an API-based payroll solution. The two companies had already been working together but now Personio is bringing Rollbox’s tech and team in-house.

The full terms of the deal remain undisclosed. However, I understand the acquisition consists of a combination of cash and equity. This sees a number of Rollbox’s investors being issued shares in Personio while others have exited entirely.
