Private equity is a type of investment where professional investors raise a large fund (generally from affluent investors) and re-invest those funds in a wide range of ways seeking the biggest possible profit. Firms in this somewhat risky industry often grab headlines for large acquisitions, sometimes controversial leveraged buyouts, and occasionally going bust and losing billions of dollars. But among many of these would-be titans of finance, a handful of firms have risen to the top as the largest and most successful private equity firms.

Private equity firms earn a spot on this list by growing a large fund or funds that typically lead to consistent profits over time. Looking at fundraising over the last five years, total assets under management, and similar criteria, here are the best private equity firms operating today.
