Sphera Funds Management

Sphera Funds Management

Sphera Funds Management was founded in 2004 by Doron Breen, Ron Senator, and Israel Mor, who died in 2023. The firm operates out of Tel Aviv and claims the longest track record among hedge fund managers in Israel. Its investor base includes large Israeli pension funds, insurance companies, financial institutions, family offices, and high-net-worth individuals — a distribution structure unusual for a firm of its size. The firm runs multiple long/short equity strategies and a real estate private equity fund. Its investment philosophy is fundamentals-driven, with a research team of over 15 analysts. Sphera's portfolio targets consistent risk-adjusted returns across market cycles; confirmed asset classes include public equities and real estate. The firm does not disclose specific portfolio holdings or deal sizes. Geographically, it focuses on Israel and global markets. Sphera employs over 20 professionals, with a management team of eight managing partners and a research team of ten analysts led by Head of Research Joshua Lipman. The firm has one office — in Tel Aviv's TOU Towers — and does not list additional offices elsewhere. No recent operational event (within 24 months) surfaced in the firm's public materials. Sphera's structural differentiator is its position as the longest-track-record hedge fund manager in a small market — Israel — where it serves large institutional clients that typically invest internally or via global managers. That local anchoring gives it a distribution advantage among domestic pension funds and insurers. The firm's governance relies on a flat partnership structure with eight managing partners, no single dominant principal.
