Bommer, a former hedge fund manager, joined Blackstone in 2021 as a senior managing director when the company was overhauling its $81 billion Blackstone Alternative Asset Management hedge fund unit known as BAAM. The Blackstone Horizon platform will now be run by an investment committee led by BAAM Global Head Joe Dowling, the sources said. Before coming to Blackstone, Bommer ran hedge fund SAB Capital for 17 years investing in stocks, debt and mortgages. Bommer was the first big hire brought in by Dowling, after he joined Blackstone in early 2021 to help overhaul the hedge fund unit. Last year Tiger Global Management lost 56% while Whale Rock Capital Management ended with a 43% loss, Reuters reported previously.
