In an investment landscape marked by volatility and shifting investor expectations, firms that thrive often owe their resilience to disciplined leadership. Few examples are as clear as H.I.G. Capital, the Miami-headquartered private equity powerhouse founded in 1993 by Tony Tamer and Sami Mnaymneh. Over three decades, the duo has transformed H.I.G. capital from a middle-market specialist into a global multi-strategy manager with nearly $70 billion in assets under management. Their stewardship has positioned the firm not merely as a survivor of cycles but as an architect of growth across turbulent markets.

Building beyond the early blueprint

From the outset, Tamer and Mnaymneh saw opportunity where others did not. While mega-funds were targeting high-profile leveraged buyouts in the 1990s, the co-founders identified untapped value in the lower and middle markets. These companies—too small for Wall Street’s largest players, yet too complex for traditional lenders—presented fertile ground for an investment approach that emphasized flexibility, operational insight, and patience.

That contrarian thesis remains embedded in H.I.G.’s DNA. Today, the firm’s portfolio spans more than 100 active companies generating over $53 billion in annual revenue. What has changed is the scope: alongside its flagship private equity business, H.I.G. now operates platforms in direct lending, distressed credit, real estate, infrastructure, and growth equity. This diversification reflects a consistent philosophy—balancing opportunism with discipline, while ensuring that the firm’s model adapts faster than the market around it.

Recent fundraising momentum

The past year has reinforced the strength of that model. In October 2024, H.I.G. closed Capital Partners VII, a $2 billion vehicle targeting the U.S. lower middle market. The fund was significantly oversubscribed, underscoring investor appetite for H.I.G.’s differentiated sourcing and value-creation strategies. More recently, in August 2025, the firm’s WhiteHorse affiliate announced the close of Middle Market Lending Fund IV at $5.9 billion—the largest direct lending fund in H.I.G.’s history. Together, these raises mark an inflection point: they demonstrate the firm’s ability to scale while retaining credibility with limited partners who prize both consistent returns and conservative stewardship.

Such fundraising achievements are not merely financial milestones. They are also reflections of the trust investors place in Tamer and Mnaymneh’s leadership. In a market where some peers have struggled to meet targets, H.I.G.’s oversubscriptions signal both alignment with investor priorities and confidence in its execution.

Strategic moves in a shifting landscape

Beyond capital formation, H.I.G. is also positioning itself for the industry’s next phase. One area of focus is the growing market for GP-led continuation vehicles. These structures, which allow fund managers to extend ownership of high-performing assets while offering liquidity options to existing investors, have emerged as an important tool in reconciling long investment horizons with shorter LP needs. For Tamer and Mnaymneh, the exploration of secondaries reflects a pragmatic recognition: private equity’s future will be defined as much by liquidity solutions as by traditional buyouts.

The firm’s deal activity also speaks to its breadth. In mid-2025, H.I.G. realized strong returns on a consumer investment while committing fresh capital to Canadian energy infrastructure, underscoring the range of sectors and geographies in which it can create value. This flexibility—shifting between retail, industrials, and financial services without diluting focus—remains a competitive edge.

Leadership with depth and reach

What makes Tamer and Mnaymneh’s partnership particularly durable is its balance. Tamer, who cut his teeth at Bain & Company and holds graduate degrees from Stanford and Harvard, brings an analytical rigor honed in strategy consulting. Mnaymneh, a Columbia and Harvard graduate who rose to managing director at Blackstone, adds transactional fluency and global dealmaking experience. Together, they have fostered a culture where entrepreneurial judgment and institutional discipline coexist.

Their impact, however, extends beyond investment returns. Both leaders are active philanthropists and board members. Tamer and his wife endowed the Tamer Center for Social Enterprise at Columbia Business School, while his civic commitments span institutions such as the Museum of Modern Art and New York Presbyterian Hospital. These engagements broaden the co-founders’ influence into education, culture, and healthcare—areas where their contributions reinforce a legacy that transcends finance.

A long-term compass

The resilience of H.I.G. under Tamer and Mnaymneh underscores a broader lesson for private markets: scale is important, but adaptability is essential. With offices across North America, Europe, and Latin America, the firm now operates on a global stage while retaining the nimbleness of its early days. As macroeconomic pressures from interest rates to geopolitical uncertainty test investor patience, H.I.G.’s emphasis on operational improvements, careful underwriting, and diversified strategies may prove more valuable than ever.

For Tony Tamer and Sami Mnaymneh, the mission has remained consistent since 1993: find opportunities overlooked by others, build enduring businesses, and align success with long-term value creation. Three decades later, that vision has not only endured but expanded—reshaping H.I.G. Capital into one of the most influential players in the middle market and beyond.
