How One Private Equity Firm Turned Middle Market Focus Into a Multi-Decade Competitive Edge
When H.I.G. Capital opened its doors in Miami in 1993, the mainstream private equity world was focused elsewhere — on large-cap buyouts, marquee brands, and headline-generating transactions. H.I.G. went in a different direction.
Its co-founder and CEO, Sami Mnaymneh, had a specific thesis: that mid-sized companies, the kind generating between $30 million and a few hundred million in annual revenue, were being systematically underserved by the capital markets. They needed not just money, but operational expertise, credit sophistication, and hands-on ownership. H.I.G. was built to provide all three.
More than 30 years later, that thesis has produced a firm with $70 billion in capital under management, more than 400 completed investments, and a current portfolio generating combined revenues north of $53 billion.
The Background of Sami Mnaymneh
Mnaymneh’s path to private equity ran through some of the most demanding academic programs in the country. He graduated first in his class at Columbia University, earning his undergraduate degree summa cum laude, then completed both a law degree and an M.B.A. — both with honors — at Harvard. He launched his finance career at Morgan Stanley before joining The Blackstone Group as a Managing Director.
That combination of legal training and investment banking experience proved useful in private equity, where deal structuring, credit underwriting, and portfolio management often require navigating complex regulatory and contractual terrain. At H.I.G., those skills became embedded in the firm’s approach to every transaction.
H.I.G.’s credit platform reflects that DNA. H.I.G. WhiteHorse Middle Market Lending Fund IV closed at $5.9 billion, drawing capital from pension funds, sovereign wealth funds, endowments, and family offices across multiple continents. The fund focuses on senior secured loans to companies with EBITDA generally between $30 million and $100 million — the same tier H.I.G. has targeted since its founding.
Staying Disciplined While Scaling
One of the more interesting questions about H.I.G.’s growth is how it has managed to preserve its middle market focus while building a platform that now spans seven distinct investment strategies and 19 global offices. Firms that grow quickly often drift upmarket, chasing larger transactions with higher fees and more visible returns.
H.I.G. has resisted that drift, at least in its core equity and credit businesses. Its middle market LBO Fund IV continued the same investment strategy the firm has applied since the 1990s: operationally intensive buyouts of companies that benefit from hands-on ownership.
Recent transactions illustrate the breadth of sectors H.I.G. operates in — from home warranty services to healthcare technology to European logistics. The firm sold its water equipment portfolio company to Berkshire Partners in a transaction covered by financial media, one of dozens of portfolio exits completed in recent years.
Mnaymneh, who has served on academic boards at both Columbia and Harvard Law, has built H.I.G. into one of Florida’s most prominent financial institutions. His name frequently appears on rankings of Florida’s wealthiest residents, a reflection of how thoroughly H.I.G.’s success has tracked his own.
