London-based private equity firm IK Partners has closed its tenth mid-cap fund, Fund X, having reached its hard cap of €3.3bn, making it the largest fund the firm has raised to date.
IK’s previous mid-cap fund, IK IX, raised €2.85bn in 2020.
According to the firm, the new fund attracted significant interest from institutional investors across Emea (64%), Asia (20%) and the Americas (16%), with a record amount of capital raised from limited partners investing in IK funds for the first time.
The announcement follows a period of record activity for the Firm which saw IK invest in 20 new companies and exit 11 since the start of 2024.
IK X has already made seven investments to date and will continue investing in established European mid-market businesses valued above €200 million across four core sectors of business services, healthcare, consumer and industrials.
Christopher Masek, CEO and founder of IK Partners, said: “We are grateful to have once again secured the support of our investors to continue delivering on the strategy of our flagship fund, supporting exceptional businesses in the European mid-market to achieve their full potential.
“After a record year of activity in 2024 and strong start to 2025, we look forward to maintaining this momentum and driving value across the entire IK platform.”
