The Medallion fund is considered to be one of the most successful hedge funds ever. It has averaged a 71.8% annual return, before fees, from 1994 through mid-2014. The fund has been closed to outside investors since 1993 and is available only to current and past employees and their families. The firm bought out the last investor in the Medallion fund in 2005 and the investor community has not seen its returns since then. About 100 of Renaissance's 275 or so employees are what it calls "qualified purchasers", meaning they generally have at least $5 million in assets to invest. The remaining are "accredited investors", generally worth at least $1 million.
