OC’s Wealthiest 2025: Joseph Edelman

THE MONEY: In 1999, founded New York-based hedge fund firm with focus on life sciences and biotechnology. Website motto: “We think and act like scientists.” $8B AUM. Invested in Irvine-based Beta Bionics, a diabetes medtech that went public in January at almost $1B valuation.

RECORD BREAKER: Paid in 2021 $70M for an oceanfront mansion in the exclusive Laguna Beach enclave of Abalone Point in the Irvine Cove community, home to 12 oceanfront homes.
