About IMM Investment
IMM Investment Corp. is a prominent multi-asset alternative investment firm based in Seoul, South Korea. Founded in September 1999, the firm manages approximately USD 7.7 billion in assets as of 2025. It is recognized as a pioneer in the Venture Capital and Private Equity sectors in Korea, offering a diversified asset strategy among Korean general partners.
The company focuses on five main alternative asset classes: Venture Capital, Growth Equity, Infrastructure, Real Estate, and Fund of Funds. IMM Investment provides multi-stage investments to support innovative entrepreneurs from early deve
IMM Investment was founded in 1999 and is headquartered at the Gangnam Finance Center in Seoul. No source I found names the founders. The firm also has offices in Hong Kong and Tokyo. IMM HK, its overseas arm, was established in 2019. Its flagship funds there include a Clean Energy Transition Fund series for North America and venture and private debt funds covering MENA and Asia. Tracxn lists a team of 71 people, and IMM HK's LinkedIn page cites 80+ dedicated professionals across four countries. The only named executive tied to AI-related investing in the sources is Kim Byung-hun, Head of Infrastructure, who commented on the SK Horizon deal. The firm does not publish a named AI team or a list of AI partners.
IMM invests in AI through two routes. In venture, it joins Korean AI rounds, sometimes leading and often as a co-investor. In infrastructure, it takes large equity stakes in AI data center assets. In August 2026, SK Telecom announced SK Horizon, a new AI data center company spun out of SK Broadband. SKT signed a definitive agreement with KKR funds and the IMM Investment-Stonebridge consortium for a combined KRW 3.08 trillion (about US$2.2 billion) equity investment. After all phases close, KKR is expected to hold 29% and the IMM consortium 20%, while SKT keeps 51% and management control. In May 2026, IMM took part in the $31.4M (KRW 47 billion) seed round of Asteromorph, a Seoul AI research lab building what it calls scientific superintelligence. BonAngels Venture Partners led that round.
IMM describes its investing as multi-stage, from early stage to pre-IPO. The AI rounds above range from seed to Series A, plus a very large infrastructure equity deal. IMM does not publish a check size policy. One third-party database, Private Equity List, gives a typical range of $10M to $50M and lists Seed through late stage. Founders should treat that range as unverified and as covering the whole firm, not only AI. IMM also does not publish whether it leads or follows in a given round. Tracker data shows it leading MangoBoost's Series A and co-investing in other AI rounds.
