Capstone Capital, LLC was founded in 2003 by Randall A. Hack to invest in private companies, with a special focus on wireless telecommunications. From 2003 through 2014 Capstone invested both for its own account and in partnership with Berkshire Partners, a Boston-based private equity firm with over $8 billion under management. Mr. Hack served as an Advisory Director of Berkshire from 2002-2014. In that capacity he assisted Berkshire in identifying and assessing private companies seeking to raise capital.
Mr. Hack began his career in 1972 with Corporate Property Investors, a private REIT which invested in commercial real estate throughout the U.S. In 1979 he founded RH Development Company to acquire and develop properties in Connecticut and New Jersey. RH Development’s principal activity was the development of a major light industrial and office park at Exit 8A of the New Jersey Turnpike. Mr. Hack sold his interest in RH Development in 1988, and it operates today as Matrix Development Company.
From 1990 through 1994 Mr. Hack served as the President of The Princeton University Investment Company, which oversees Princeton University’s endowment and currently has $22 billion of assets under management. In that role Mr. Hack built a team of two-dozen professionals who conceived and implemented a series of global investment initiatives in such areas as domestic and international equities, hedge funds, private equity, venture capital, and other private market assets such as real estate, oil and gas holdings, and timber.
In 1995, with the support of Princeton University’s Board of Trustees, Mr. Hack founded Nassau Capital, LLC, a private investment firm which he served as Senior Managing Director. Nassau Capital and its principals invested in privately held companies and assets solely on behalf of Princeton University’s endowment. Over a period of six years Nassau invested in one hundred and fifty specialized limited partnerships, both domestically and internationally, in such areas as private equity, venture capital, real estate, timber and energy assets. The market value of Nassau’s aggregate positions in these investment funds exceeded $2 billion at the peak of this investment program. During this same period, Nassau also invested over $500 million directly in three-dozen private companies in these same specialized asset classes, producing a gross IRR of 31% over the twelve years from inception of this direct investment program.
Mr. Hack is a 1969 summa cum laude graduate of Princeton University and a member of Phi Beta Kappa. In 1972 he received his MBA from Harvard University. He has served on numerous corporate boards, both private and publicly traded, including Crown Castle International [NYSE: CCI], the second largest owner and operator of cellular towers in the United States. Mr. Hack also serves as a Director of Tower Development Corp (“TDC”), a private company created in 2008 with backing from Berkshire Partners.
