On 29 November 2017, Eurazeo invested close to €100 million in Rhône Group, a US and UK investment firm, for 30% of the company's capital. One month later, on 29 December 2017, Eurazeo announced the acquisition of a 70% interest in Idinvest Partners, thereby doubling the amount of its assets under management, from €8 billion to €16 billion. These two large-scale acquisitions coincided with Virginie Morgon's full assumption of office at the head of the company on 19 March 2018. Patrick Sayer had led Eurazeo for fifteen years.
