# Bain Capital

Bain Capital is a global private investment firm founded in 1984, managing $185 billion in assets. It invests across private equity, venture capital, credit, and real estate, and has increasingly focused on artificial intelligence opportunities.

Bain Capital, LP is an American private investment firm headquartered in Boston, Massachusetts, with approximately $185 billion in assets under management. The firm specializes in private equity, venture capital, credit, public equity, impact investing, life sciences, crypto, technology opportunities, and real estate, operating across multiple industry sectors and geographic regions. Founded in 1984 by partners from the consulting firm Bain & Company, Bain Capital has grown into one of the world's largest alternative asset managers, ranked 13th in Private Equity International's PEI 300 ranking in June 2023.

Since its establishment, Bain Capital has invested in or acquired hundreds of companies, including AMC Theatres, Burger King, Domino's Pizza, Dunkin' Donuts, Hospital Corporation of America (HCA), Staples, Toys "R" Us, Warner Music Group, and The Weather Channel. The firm's actions during its first 15 years became a subject of political and media scrutiny due to co-founder Mitt Romney's later political career, particularly his 2012 presidential campaign.

## History and Founding

Bain Capital was founded in 1984 by Bain & Company partners Mitt Romney, T. Coleman Andrews III, and Eric Kriss, after Bill Bain offered Romney the chance to lead a new venture that would invest in companies and apply Bain's consulting techniques to improve operations. The early team included Fraser Bullock, Robert F. White, Joshua Bekenstein, Adam Kirsch, and Geoffrey S. Rehnert. Romney initially served as president and managing general partner, later becoming managing director and CEO, and was the sole shareholder of the firm.

The founders spent a year raising $37 million in initial capital, with Bain partners contributing $12 million of their own money and sourcing the rest from wealthy individuals. Early investors included Boston real estate mogul Mortimer Zuckerman, New England Patriots owner Robert Kraft, and members of elite Salvadoran families such as Ricardo Poma, whose capital fled the country's civil war. These Latin American investors contributed $9 million, primarily through offshore companies registered in Panama.

Although founded by Bain & Company executives, Bain Capital was a completely separate company, not an affiliate or division. Initially, the two firms shared offices at Copley Place in Boston and a similar approach to improving business operations, but they implemented protections to avoid sharing information and allowed Bain & Company executives to veto investments that posed potential conflicts of interest.

## Early Investment Strategy

The Bain Capital team was initially reluctant to invest its capital. By 1985, things were going poorly enough that Romney considered closing the operation and returning investors' money. The partners saw weak spots in so many potential deals that by 1986, very few had been completed.

At first, Bain Capital focused on venture capital opportunities. One of its earliest and most notable venture investments was in Staples, Inc., the office supply retailer. In 1986, Bain provided $4.5 million to two supermarket executives, Leo Kahn and Thomas G. Stemberg, to open an office supply supermarket in Brighton, Massachusetts. The fast-growing retail chain went public in 1989; by 1996, it had grown to over 1,100 stores, and by fiscal year-end January 2012, Staples reached over $20 billion in sales, nearly $1.0 billion in net income, 87,000 employees, and 2,295 stores. Bain Capital eventually reaped a nearly sevenfold return on its investment, and Romney sat on the Staples board of directors for over a decade.

Another successful investment occurred in 1986 when $1 million was invested in medical equipment maker Calumet Coach, which eventually returned $34 million. A few years later, Bain Capital invested in the technology research firm Gartner Group, which returned a 16-fold gain. By 1989, Bain's first fund of $37 million had been deployed across twenty companies, generating an annualized return in excess of 50 percent. The second fund, raised in 1987, deployed $106 million into 13 investments.

## Expansion and Affiliates

In the 1990s, Bain Capital started several affiliates that supported its private equity and other asset classes. The long-short equity hedge fund Brookside Capital was founded in 1996, and Sankaty Advisors, the company's fixed income affiliate, was started two years later. Building affiliates for the firm was directed by three conditions: that it leveraged its core skills, that one of its managing directors had a leadership role, and that the new business invested in an attractive asset class.

Beginning in 1989, the firm adjusted its strategy from venture capital to focus on leveraged buyouts and growth capital investments in more mature companies. Their model was to buy existing firms with money mostly borrowed against their assets, partner with existing management to apply Bain methodology to their operations, and sell them off in a few years. Existing CEOs were offered large equity stakes in the process, owing to Bain Capital's belief in the emerging agency theory that CEOs should be bound to maximizing shareholder value rather than other goals.
