Top Private Equity Firms in South Korea
South Korea's private equity market has come a long way since its 2005 reopening.
Committed capital reached KRW 136.4 trillion by the end of 2023. Korean PE firms raised an estimated KRW 70 trillion in new capital through 2024 alone.
Private equity now accounts for a meaningful share of total M&A deal value in the country. Combined with the market's concentration in Seoul, and its split between large-cap control deals and a deep venture and growth ecosystem, that scale makes firm selection more consequential than it might look from outside.
The directory tool above lists every PE firm Private Equity List tracks for South Korea, filterable by industry, stage, region, and check size. What it can't tell you is how a firm was built, what its track record actually looks like, or how it differs from three others chasing the same sector.
The profiles below fill that gap, covering ten of the most active and best-documented firms in the database. Read the full directory first to narrow your list, then use the context here to understand what you're actually choosing between.
1. MBK Partners
The largest independent private equity firm in North Asia by AUM, MBK Partners was founded in March 2005 by Michael ByungJu Kim and five other founding members, and now manages approximately $33 billion in assets. Its geographic mandate is deliberately narrow: Korea, Japan, and China only, with no ambition to build a pan-Asian platform beyond those three markets.
That focus, combined with a typical investment size of $300 million to $1 billion per deal, means MBK is not a firm that a growth-stage founder will encounter. Its relevance is to large Korean corporates considering a carve-out, succession-driven family business owners, or investors benchmarking the top end of the domestic buyout market.
The firm's own website describes its AUM as over $30 billion, consistent with the 2026 Wikipedia figure of $33 billion. By either measure it sits in a different weight class from every other firm on this page.
2. Hahn & Company
Hahn and Company was founded in 2010 by Scott Hahn, who came from Morgan Stanley, making it one of the newer entrants among Korea's established buyout firms. In the fourteen years since, it has invested in over 38 companies and deployed over $31 billion across its funds. Fund III had a target of $2.5 billion (2019), and Fund IV targeted $3.25 billion when it was in market in early 2024, which reflects consistent fund-size growth across its short history.
The firm focuses on control investments, which separates it from the growth-minority players further down this list. Its sector coverage is broad, including B2B services, media, and transportation, so the common thread is control-oriented deal structure rather than a single industry thesis.
For a company that has reached the scale where a full buyout or a majority recapitalization is the right next step, Hahn and Company is one of two firms on this list, alongside MBK Partners, that is structurally set up for that transaction type.
3. IMM Private Equity, Inc.
IMM Private Equity describes itself as backed by more than 15 investors, which the firm characterizes as the broadest LP base of any PE firm in Korea. Founded in 2006, it has grown to approximately KRW 6.9 trillion in total AUM, and its flagship RoseGold fund series has been running since RoseGold I closed in 2008 at USD 272 million. RoseGold II followed in 2012 at USD 657 million, representing more than a doubling of fund size across a single cycle.
The firm's minimum ticket size is $100 million with a typical hold period of three to five years, which positions it firmly in the mid-to-large buyout and growth equity space rather than venture. A founder raising a Series A will not fit IMM's mandate, but a company at the stage where it is considering a significant institutional partner for a major growth push or ownership transition will find IMM one of the more institutionally credentialed options available domestically.
4. STIC Investments
STIC started in 1999 as a venture capital firm and launched its private equity business separately in 2006, which gives it an unusual dual heritage. The buyout and growth capital practice that most people refer to today when they use the name STIC sits on top of that earlier VC foundation, and the firm has grown to an accumulated AUM of KRW 8.8 trillion (approximately USD 6.5 to 6.7 billion) as of early 2024. With 43 investment professionals and over 110 invested companies, the team is comparably staffed to firms managing similar AUM internationally.
That venture capital origin still shapes how the firm evaluates growth businesses, even within its PE mandate. Companies that have scaled past venture territory but retain characteristics more associated with growth equity than pure buyout will find STIC's analytical background relevant.
5. Korea Investment Partners
Korea Investment Partners has been operating since 1986, making it the oldest firm on this list by a significant margin. It is a subsidiary of Korea Investment Holdings, which gives it institutional backing that most independent GPs cannot match. The firm manages USD 4 billion across 58 active funds, and online sources record 1,208 total investments, a figure that reflects nearly four decades of consistent deployment across early and growth-stage companies.
The track record on liquidated funds is concrete: since 2001, 18 funds have been fully returned with an average multiple of 2.0x and an IRR of 16.7 percent. For LPs or founders trying to assess Korea Investment Partners against newer alternatives, those numbers are the right starting point. The firm targets early- to growth-stage investments, which means its deal size and entry point differ substantially from the large buyout firms earlier in this list.
6. Aju IB Investment
Founded in 1974, Aju IB Investment is the oldest firm in this group, predating Korea's modern PE market by decades. Its longevity shows up in its operational data: 168 recorded investments, 141 portfolio companies, and 46 fully liquidated and exited funds by the end of 2025. Total AUM stands at over KRW 2.5 trillion against a capital base of KRW 53.9 billion (approximately USD 48 million).
Fifty years of continuous operation across multiple Korean economic cycles, including the 1997 Asian financial crisis and the global financial crisis of 2008, is a different kind of track record than a firm that has run two or three fund cycles in a post-2005 market. For companies or LPs who weight institutional continuity and Korea-specific cycle experience, Aju's history is the distinguishing factor.
7. Stonebridge Capital
Stonebridge Capital was founded in 2008 and has accumulated $3 billion in AUM as stated on the firm's own site, with 167 recorded investments across 128 portfolio companies. Its sector focus is life science and healthcare, which makes it one of the more narrowly specialized firms on this list.
That specialization matters for founders in healthcare-adjacent categories. A generalist PE firm evaluating a Korean medtech or biopharma company will apply a generic framework; Stonebridge has built its portfolio around that category specifically. The firm is Seoul-based, so it operates in the same geographic concentration as the rest of the market, but its investment thesis is considerably more defined by industry than most of its domestic peers.
8. LB Investment
LB Investment has been operating since 1996 and has made 233 total investments according to Superscout data, with approximately $1.2 billion in AUM. The firm's sector targets span biotech and life science, business services, and clean tech, a combination that reflects a science and technology orientation rather than pure industrials or consumer.
LB Investment Fund No. 20 raised 541.5 billion KRW when it closed in 2014, which gives a sense of the fund sizes the firm has operated at in its PE business. The clean tech inclusion is notable given how few Korea-focused PE firms explicitly include it as a primary target, and for companies operating at the intersection of life science and environmental technology, LB's mandate covers more relevant ground than most domestic alternatives.
9. Smilegate Investment
With 252 recorded investments and 203 portfolio companies, Smilegate Investment has one of the highest investment counts among the firms on this list relative to its AUM, which sits at approximately KRW 1.1 trillion (around USD 800 to 850 million depending on the source). Founded in 1999, the firm operates from Gangnam in Seoul and deploys through both venture capital and buyout strategies, with sector coverage that includes environmental businesses alongside more conventional technology and services categories.
The high investment count relative to fund size indicates a portfolio construction approach that skews toward smaller individual positions across a wider set of companies, rather than concentrated control deals. That makes Smilegate's profile more relevant to small and mid-sized businesses looking for institutional backing without giving up majority control, and to LPs seeking broad Korean market exposure through a single vehicle.
10. InterVest
InterVest was founded in 1999 and has been recognized as a ten-year consecutive A-rated venture capital investor, a designation that reflects consistent performance scoring by Korean regulators over a full decade. AUM figures across sources range from $580 million to $1.2 billion as of 2021, with the firm headquartered in Seoul and focused on information technology, healthcare, and financial services.
The regulatory performance rating is a differentiator worth taking at face value. In a market where many firms are privately held and limited in what they disclose, a sustained decade of top-rated assessments by an external body provides a form of third-party validation that most LP due diligence processes would otherwise have to reconstruct from first principles.
Let’s Recap
The ten firms above represent a wide range of strategies. Pairing them against each other makes the differences clearer than reading each one in isolation.
MBK Partners and Hahn and Company are structured around large control buyouts, with minimum deal sizes that exclude most growth-stage businesses by design. IMM Private Equity sits just below that tier, with a $100 million minimum ticket and a multi-LP institutional model giving it scale comparable to a regional fund. STIC Investments covers similar AUM territory but brings a venture capital heritage that shapes how it evaluates earlier-stage businesses moving into PE territory.
Korea Investment Partners and Aju IB Investment have the longest track records, with fund-liquidation data that supports genuine historical analysis rather than extrapolation from a short run. Stonebridge Capital and LB Investment are the clearest sector specialists, in healthcare and life science respectively, with LB also covering clean tech. Smilegate Investment and InterVest operate at lower per-deal concentration, with meaningful regulatory or performance benchmarking behind them, making them more accessible entry points for smaller companies or LPs building first exposure to Korea.
The most useful filters to apply, in sequence:
- Check size: below the $100 million threshold, the buyout-oriented firms at the top of this list aren't practical options regardless of sector overlap.
- Deal structure: if you need a control deal, that narrows the field to MBK and Hahn and Company specifically.
- Sector: if specialisation is the priority, Stonebridge, LB, and InterVest each have defined theses that produce a fundamentally different diligence process than a generalist firm.
