Heidrick & Struggles International Inc. (NASDAQ: HSII) closed on its acquisition of Atreus GmbH, a Munich, Germany-based firm that provides experienced interim C-suite-level executives. The deal was announced in January.

Atreus will constitute Heidrick’s on-demand talent segment along with US-based Business Talent Group, which Heidrick acquired in 2021.

Terms of the transaction were not announced.

“Our on-demand talent business is core to our overall growth strategy and a key client imperative that will only accelerate as companies continue to seek alternative ways to approach talent management with speed, agility and flexibility — whether it’s through on-demand access to executive leaders for interim roles or strategic project work,” said Krishnan Rajagopalan, Heidrick president and CEO.

The acquisition of Atreus is a highly complementary investment for Heidrick & Struggles, according to Rajagopalan.

“The addition of Germany, a strategically important market for the firm, along with our existing on-demand talent businesses in the United States and the United Kingdom, gives us a strong springboard to scale this powerful platform across Europe and globally,” Rajagopalan said.

Plans call for the Atreus brand to remain. In addition, Atreus’ management team, led by Harald Linné and Rainer Nagel, will remain in place.

Chicago-based Heidrick & Struggles is ranked by SIA as the second-largest retained search firm in the US.
