Private Equity Executive Maintains Hands-On Role After 32 Years
Private Equity Executive Maintains Hands-On Role After 32 Years
Most private equity founders transition to advisory roles within two decades of launching their firms. Sami Mnaymneh has taken a different path. After 32 years leading HIG Capital, he continues serving as founder, executive chairman and CEO, personally approving every investment the firm makes.
HIG Capital now manages $70 billion across seven investment strategies, operates 19 offices worldwide and employs over 1,000 people. The firm has invested in more than 400 companies since Mnaymneh and Tony Tamer established it in 1993.
Mnaymneh’s continued operational involvement in a firm of this scale represents an unusual management approach in an industry where founders typically delegate investment authority as organizations grow.
Educational Background
Before entering finance, Mnaymneh completed extensive academic training. He graduated first in his class at Columbia University, earning a B.A. summa cum laude. He then attended Harvard University, where he earned both a J.D. from Harvard Law School and an M.B.A. from Harvard Business School, receiving honors in both programs.
The combination of legal and business education provided tools for structuring complex transactions. Private equity deals require navigating corporate law, securities regulations, tax structures and contractual arrangements. Many practitioners hold either business degrees or law degrees. The dual credential offered advantages in understanding transactions from multiple perspectives.
Following graduate school, Mnaymneh joined Morgan Stanley in New York, working in the investment bank’s private equity activities. He subsequently moved to The Blackstone Group, serving as a managing director. The experience at Blackstone, one of the industry’s pioneering firms, exposed him to sophisticated investment practices and portfolio management approaches.
Identifying Market Gaps
Working at major financial institutions gave Mnaymneh insight into market dynamics. Large private equity firms in the early 1990s focused primarily on transactions with enterprise values exceeding $500 million. Middle-market companies with values between $50 million and $500 million received limited attention.
This segment appeared underserved despite representing thousands of businesses needing growth capital, recapitalization or ownership transition solutions. Less competition for middle-market deals suggested better entry valuations might be available. Middle-market companies often had significant operational improvement potential compared to mature, well-managed larger corporations.
However, middle-market investing required different capabilities than large-cap transactions. Smaller companies typically lacked sophisticated management teams, robust financial systems and operational best practices. Creating value required working directly on business fundamentals rather than relying solely on financial engineering.
In 1993, Mnaymneh partnered with Tamer to launch HIG Capital, targeting this market segment. The firm would provide both equity and debt capital to middle-market companies, with investment professionals who combined financial expertise with operating experience.
Platform Development
HIG Capital began as a traditional leveraged buyout fund targeting manufacturing and service businesses. The firm gradually expanded to include seven distinct investment strategies over three decades.
The platform now encompasses private equity, growth equity, direct lending, real estate, infrastructure, special situations debt and growth-stage healthcare. Each strategy addresses different opportunities within the middle market.
Growth equity targets businesses not ready for buyouts but needing capital to scale. Direct lending provides flexible debt solutions as banks reduced middle-market lending. Real estate focuses on value-add properties requiring repositioning. Infrastructure investments target essential service providers with stable cash flows.
The diversified approach allows HIG Capital to provide multiple forms of capital to companies at different stages. A business might receive growth equity initially, later refinance with HIG Capital debt, then pursue a management buyout backed by the private equity funds.
Multiple strategies also generate more consistent cash flows to limited partners than relying solely on buyout exits. Debt funds produce regular income. Real estate and infrastructure generate periodic distributions. Buyout funds return capital through exits concentrated in later fund years.
Direct Lending Growth
WhiteHorse, HIG Capital’s direct lending arm, has grown into one of the firm’s largest strategies. The platform launched to provide middle-market companies with flexible debt capital as traditional bank lending contracted following the 2008 financial crisis.
WhiteHorse has invested approximately $18 billion in 285 companies since inception. The platform targets senior secured loans to both sponsor-backed and non-sponsor borrowers with EBITDA between $30 million and $100 million.
In August 2025, WhiteHorse closed its fourth fund at $5.9 billion, one of the largest middle-market lending funds raised that year. The successful fundraising demonstrated institutional investor demand for the strategy.
Direct lending has grown more attractive as interest rates have risen. Senior secured floating rate loans offer compelling returns while providing downside protection through their senior position in capital structures. The strategy appeals to investors seeking current income with lower volatility than equity investments.
Centralized Control
Mnaymneh maintains personal approval authority over all capital commitments HIG Capital makes. This centralized decision-making is uncommon for firms managing $70 billion. Most private equity platforms delegate investment authority to fund managers or investment committees at this scale.
The approval requirement means Mnaymneh reviews transactions across seven strategies, 19 offices and multiple continents. Each transaction requires understanding industry dynamics, assessing management quality, evaluating competitive positioning and determining appropriate capital structures.
Centralized decision-making ensures consistency in investment criteria and risk management. It prevents individual teams from pursuing transactions that don’t align with firm-wide standards. The process forces disciplined due diligence and strategic analysis.
However, the structure also creates potential constraints. Investment professionals must coordinate with Mnaymneh’s schedule to present opportunities. Time-sensitive deals may face delays. Competitors with distributed authority can sometimes execute faster.
Three decades of results suggest Mnaymneh believes the benefits outweigh the costs. The firm has continued growing while maintaining this management structure.
International Expansion
HIG Capital operates affiliate offices across five continents. European locations include Hamburg, London, Luxembourg, Madrid, Milan and Paris. Latin American offices span Bogotá, Rio de Janeiro and São Paulo. Additional offices in Dubai and Hong Kong provide presence in the Middle East and Asia.
Geographic diversification provides access to deal flow beyond U.S. markets. European middle-market private equity faces somewhat less competition than U.S. markets in certain sectors and geographies.
Recent transactions demonstrate the global platform’s activity. Investments in 2025 included Finnish waste management company Fluo Group, Spanish occupational health provider Avanta Salud, German machine tool manufacturer HELLER Group and French textile services business France Workwear.
International expansion required building local teams with regional expertise. European deals involve different legal systems, tax structures, labor regulations and banking relationships than U.S. transactions. HIG Capital developed capabilities in each market rather than attempting remote management.
Secondaries Initiative
HIG Capital announced plans in late 2025 to raise $1.5 billion for a vehicle focused on GP-led continuation funds. The initiative represents entry into the growing secondaries market.
The strategy involves investing in continuation vehicles other private equity firms create to extend ownership of high-performing assets. These structures allow sponsors to retain ownership beyond typical holding periods while providing liquidity to original limited partners.
Continuation funds have grown popular as traditional exit options have become constrained. Elevated interest rates have curtailed both IPO activity and strategic acquisition volumes. Continuation vehicles provide alternative liquidity mechanisms for private equity firms and their investors.
To build this capability, HIG Capital recruited four executives from Morgan Stanley’s private equity secondaries team. Managing Director Dan Wieder leads the group, which brings decades of combined experience in secondaries investing.
HIG Capital plans to invest at least $50 million in approximately 20 single-asset continuation vehicles, focusing on middle-market companies across sectors including business services, industrials, healthcare and consumer businesses.
Recent Activity
HIG Capital’s transaction activity in 2025 demonstrates the range of opportunities the firm pursues. Investments included destination management companies 360 Destination Group and CSI DMC, Microsoft cloud solutions provider Quisitive, revenue cycle management company GetixHealth and home warranty provider Rely Home.
The firm also completed several portfolio company exits. Sales included Soleo Health to Court Square Capital and WindRose Health Investors, SoldierPoint Digital Health to GovCIO, United Flow Technologies to Berkshire Partners and EYSA Group to Tikehau Investment Management.
Exit timing depends on portfolio company development and market conditions. Extended holding periods have become common as traditional exit markets have slowed. Many private equity funds now hold portfolio companies seven years or longer, compared to historical averages of four to six years.
Performance Measures
Private equity firms rarely disclose detailed performance data. However, certain indicators suggest HIG Capital has generated competitive returns. The firm successfully raised successively larger funds over three decades. Institutional investors allocate capital based on track records rather than marketing materials.
The ability to attract $5.9 billion for a single lending fund demonstrates investor confidence. Pension funds, endowments and other institutional investors conduct extensive due diligence before committing capital. Large allocations reflect conviction in strategy and execution.
HIG Capital’s portfolio scale provides another measure. Managing over 100 active investments requires consistent deal flow and effective portfolio management. The firm must generate sufficient exits to return capital to limited partners while maintaining steady deployment rates.
Academic Involvement
Mnaymneh has maintained connections to educational institutions throughout his career. He has served on the Board of Columbia College and the Dean’s Council of Harvard Law School.
These advisory roles involve meeting with university leadership, providing input on curriculum and helping institutions adapt to changing business environments. Board members typically contribute financial support alongside their time and expertise.
Academic involvement serves multiple purposes. It maintains connections to alma maters, supports educational missions and provides recruitment opportunities. Many private equity firms draw talent from universities where partners maintain relationships.
Leadership Questions
Mnaymneh and Tamer remain actively involved more than 30 years after founding HIG Capital. This longevity raises questions about succession planning and leadership transition.
The firm has developed senior management across regional offices and strategy-specific funds. Managing directors operate with substantial autonomy, though Mnaymneh retains ultimate approval authority. This structure balances operational independence with centralized oversight.
HIG Capital has not publicly addressed succession timing or transition plans. The development of deep leadership ranks suggests preparation for eventual change, though timing remains unclear.
Succession planning presents challenges for many private equity firms. Founders often establish distinctive investment approaches and organizational cultures that can prove difficult to maintain through leadership transitions. Balancing continuity with necessary change requires careful planning.
Market Environment
The private equity industry faces challenges entering 2026. Interest rates remain elevated compared to the previous decade, increasing borrowing costs and reducing leverage multiples that historically amplified returns. Exit markets have slowed as both strategic buyers and public markets show restraint.
These conditions create performance pressure. Private equity has traditionally relied on multiple expansion and financial leverage to generate returns. With purchase price multiples high and debt expensive, operational improvements must contribute more to value creation.
The middle market where HIG Capital operates may face somewhat different dynamics than large-cap transactions. Smaller companies have limited access to public capital markets, creating consistent demand for private capital regardless of broader market conditions. Competition for deals remains intense but may be less extreme than for transactions attracting numerous mega-funds.
Mnaymneh and his team have managed through multiple downturns. The firm navigated the dot-com bust, the 2008 financial crisis and the COVID-19 pandemic while continuing to raise capital and complete transactions. This experience provides perspective that newer firms lack.
Current Portfolio
HIG Capital’s current portfolio exceeds 100 companies with combined revenues above $53 billion. Portfolio companies span diverse sectors including healthcare, technology, business services, consumer products, industrial services and real estate.
Portfolio company performance ultimately determines returns to investors. Middle-market companies face challenges including labor shortages, supply chain disruptions, regulatory changes and technological disruption. HIG Capital’s operational resources aim to help portfolio companies navigate these issues.
The firm employs over 500 investment professionals, many with operating backgrounds in addition to finance expertise. This operational focus distinguishes HIG Capital from purely financial buyers. The firm works directly with portfolio companies on initiatives including sales force expansion, supply chain optimization, add-on acquisitions and management team development.
Future Direction
As HIG Capital approaches its 35th anniversary, Mnaymneh continues pursuing growth opportunities. The secondaries initiative, ongoing European expansion and fundraising across multiple strategies indicate sustained ambitions.
Whether a $70 billion platform can continue growing depends on market conditions and execution quality. Larger firms face challenges deploying capital efficiently while maintaining return standards. Some private equity firms have struggled after growing too large to execute their original strategies effectively.
HIG Capital’s multi-strategy approach provides flexibility but requires coordinating complex operations. Managing seven investment strategies across 19 offices demands sophisticated systems and communication processes.
The personal approval requirement Mnaymneh maintains may become increasingly difficult to sustain as transaction volumes grow. At some point, centralized decision-making could constrain the firm’s ability to pursue opportunities across multiple strategies and geographies simultaneously.
Three decades of results suggest Mnaymneh has built a durable organization. The firm survived multiple market cycles, raised substantial capital across strategies and maintained investor confidence through changing conditions.
How much longer Mnaymneh maintains his current operational role remains unclear. The executive who identified middle-market opportunities in 1993 and built a global platform continues leading one of the industry’s most active firms after 32 years.
