Harel Hertz Investment House
Harel Hertz Investment House is a Tel Aviv-based single-family office investing across Israeli venture and US real estate.
Harel Hertz Investment House
The Harel Hertz Investment House reflects a dual-pillar strategy combining direct technology investments in Israel with hard-asset real estate exposure in the United States. While the exact founding date remains unpublicized, the office maintains a presence in Tel Aviv, Herzliya, and New York, suggesting transatlantic capital flows that are common among Israeli family offices seeking to diversify beyond the local startup ecosystem. The wealth origin has not been publicly disclosed by the principal. The office's investment activity spans early-stage Israeli venture deals alongside direct US commercial real estate acquisitions. This combination allows the firm to balance high-upside technology exposure with the yield and appreciation profiles of American property markets. Geographic focus is concentrated in Israel's tech corridor and major US gateway cities, including New York. The firm does not publicly disclose its total assets under management or aggregate deployment figures, which is consistent with a single-family office that avoids regulatory registration triggers. Harel Hertz, the named principal, runs an operation that appears lean, with no publicly listed team size or additional named professionals. The New York office provides an on-the-ground presence for sourcing and managing US real estate assets, a common setup for Israeli family offices targeting Manhattan office, multifamily, or retail properties. The firm has not publicized recent fund closes or specific portfolio company names, maintaining a low profile that suggests a preference for proprietary deal flow over marketed transactions. The structural differentiator lies in the portfolio construction itself: marrying illiquid US real estate with Israeli venture capital in a single-family office removes the pressure to mark-to-market liquid positions, allowing for multi-decade hold periods on both the technology and property sides. This patience-oriented mandate, free from external LP demands, is the defining feature of the architecture.

Frequently asked questions
What investment mandate does Harel Hertz Investment House operate under?
The firm operates a dual mandate targeting Israeli technology ventures and US commercial real estate. This structure provides natural diversification away from the concentrated tech risk profile common among Israel-based family offices. The office maintains a presence in both Tel Aviv and New York to execute this transatlantic strategy.
Does Harel Hertz take external capital or is it strictly a single-family office?
The firm is structured as a single-family office for Harel Hertz and does not publicly market to external limited partners. There are no indicators of it operating as a multi-family office or offering fund structures to outside investors. Its discretion and lack of public filings are consistent with a proprietary capital base.
How does the firm source its technology deals in Israel?
Given the principal's base in Tel Aviv and Herzliya, deal flow likely originates from the dense Israeli venture network of founders, angel investors, and venture capital firms. The absence of a large public team suggests reliance on direct relationships rather than a formalized institutional sourcing apparatus.
What types of US real estate does the office target?
Specific property types have not been publicly disclosed. The New York office location implies a focus on gateway-city assets, which for Israeli family offices often includes Manhattan office buildings, multifamily residential, and retail properties. These assets typically serve as long-duration inflation hedges within the broader portfolio.
Is Harel Hertz related to any publicly known operating company or prior liquidity event?
The source of the family's wealth has not been disclosed in public records. Unlike many Israeli single-family offices with visible exits from companies like Check Point, Wix, or Mobileye, Harel Hertz has not publicized a specific liquidity event or operating-company background.
