Carlyle Group Inc.
A global investment firm that manages money for institutions and wealthy clients, buying and growing companies through its private equity, credit, and AlpInvest businesses. Founded in 1987 in Washington, D.C., by five partners including David Rubenstein, it grew from a boutique firm into one of the world's largest asset managers. Its name comes not from any founder but from The Carlyle Hotel in New York, where early meetings were held — a name the hotel itself borrowed from the philosopher Thomas Carlyle.
