From the outset in 1985, Schwarzman and Peterson planned to enter the private equity business but had difficulty in raising their first fund because neither had ever led a leveraged buyout. Blackstone finalized fundraising for its first private equity fund in the aftermath of the October 1987 stock market crash. After two years of providing strictly advisory services, Blackstone decided to pursue a merchant banking model after its founders determined that many situations required an investment partner rather than just an advisor. The largest investors in the first fund included Prudential Insurance Company, Nikko Securities and the General Motors pension fund.
