NXMH

NXMH was established in 2011 by Jung-Ju Kim, co-founder of the Korean online-gaming company Nexon. Kim died in February 2022; control of the balance sheet passed to his wife Yoo Jung-hyun, who also chairs NXC Corporation. The office maintains an evergreen structure funded entirely by the Nexon liquidity event. Capital is allocated across private equity buyouts, early-stage venture, digital assets, and direct real-estate holdings. Confirmed positions include stakes in Korbit and Bitstamp, a partnership interest in Collaborative Fund, and commercial properties at 347 Bowery and 738 Broadway in New York. The firm also holds the Central Pangyo mixed-use development in South Korea and maintains exposure to European consumer and luxury sectors. Geographic reach covers Europe, North America, and Asia. The team consists of investment professionals based in Brussels with additional oversight from NXC Corporation in South Korea. Frédéric Lammens serves as Managing Director; Hendrik Ghys acts as Investment Manager and co-founder of Thalex. In the last twenty-four months the office has continued to hold its Korbit and Bitstamp equity positions without new public fundraises. Adjacent vehicles include the Nexon Foundation and the C Program philanthropic entities. NXMH differs from typical single-family offices through its hybrid mandate that blends Asian LP relationships with European direct-control investments. The structure permits majority ownership of operating companies rather than minority fund commitments, and it maintains an internal cryptocurrency desk alongside traditional private-equity activity.

Frequently asked questions

Who runs investment decisions at NXMH?

Frédéric Lammens serves as Managing Director. Investment Manager Hendrik Ghys and NXC Corporation CIO Alexander Iosilevich also participate in decisions. Yoo Jung-hyun holds ultimate oversight as family principal.

How does NXMH source proprietary deal flow?

The firm pairs Asian networks from the Nexon ecosystem with local European relationships. It frequently sources through direct outreach rather than intermediaries.

Does NXMH participate in fund commitments or only direct deals?

NXMH executes direct co-investments and SPVs. It also holds a partnership interest in Collaborative Fund but does not run a broad fund-of-funds program.

What investment stages does NXMH typically target?

The office covers early-stage venture, growth equity, and middle-market buyouts. It maintains flexibility across seed through control transactions.

Where does the underlying wealth come from?

The capital originates from Jung-Ju Kim’s founding stake in Nexon, the Korean online-gaming company. Kim liquidated a portion of that stake prior to establishing NXMH in 2011.

Does NXMH maintain philanthropic structures?

Yes. The Nexon Foundation and C Program operate separately from the investment office. Both entities focus on education and social-impact initiatives in South Korea and Europe.

What is NXMH’s known posture on co-investments alongside external GPs?

The firm prefers direct control positions but has joined external syndicates such as Collaborative Fund. It evaluates co-investments on a case-by-case basis when governance rights align with its long-term holding period.
