What ION Asset Management does
ION Asset Management is a privately held Israel-based investment management firm founded in 2006 by Stephen Levey and Jonathan Half, headquartered at 89 Medinat Hayehudim St., Building E, 13th and 14th Floor, Herzliya Pituach, with a US subsidiary (ION Macro Management LLC) at 23 East 73rd Street, New York. The firm manages approximately US$2 billion in assets under management across five separately managed strategies: ION Long/Short Fund (Israeli public equities, 2006), ION Tech Fund (technology-focused, 2015), ION Crossover Partners I and II (growth equity in Israeli tech companies, 2018 and 2019/2021), ION Macro Fund (NYC-based discretionary global macro, launched September 2024 under portfolio manager Michael Shaoul), and ION Private Equity (buyout fund for Israeli mid-market businesses, established 2026). ION positions itself as the only firm in Israel offering both public-equity and private-company investment funds, with 21 investment professionals and a self-described bottom-up, fundamental-research approach grounded in a local Israeli network of business leaders and operators.
The firm serves accredited investors only, including institutional investors, endowments, family offices, and high net-worth individuals, distributing exclusively through direct relationship-based sales supported by dedicated investor relations staff and per-fund investor portals. Revenue is generated through management fees and performance fees (carry) on the funds managed. Distribution is relationship-led via three regional heads of business development covering Israel (Shimrit Ben Hamu, joined 2017), North America (Glenn Sapadin, joined June 2023, based in Los Angeles), and EMEA (Monica Won, joined 2026, based in London).
The portfolio reflects a deep Israel-tech focus. ION Crossover Partners' disclosed portfolio includes SimilarWeb (NYSE: SMWB), Fiverr (NYSE: FVRR, exited), monday.com (NASDAQ: MNDY), Amwell (NYSE: AMWL), Taboola (NASDAQ: TBLA), BlueVine, Aqua Security, Cato Networks, Infinidat (acquired by Lenovo), Perimeter 81 (acquired by Check Point), Via (NYSE: VIA), Innovid (acquired by Mediaocean), Lusha, At-Bay, WSC Sports, Seeking Alpha, Cycode, Guardio, Eleos Health, Twill (acquired by Dario Health), and Resident (acquired by Ashley Home). ION Private Equity's disclosed investments are ScanMaster (automated ultrasonic inspection) and Izotest (testing, inspection, and certification for construction/infrastructure). The firm has no disclosed parent company, is not publicly traded, and reports no funding rounds.

ION Asset Management competitors and assessment
Company assessmentBroad incumbents
- Millennium Management: One of the largest multi-strategy hedge fund platforms globally. Competes for the same institutional allocator dollars as ION Long/Short and ION Tech, though at vastly larger scale and without a private-markets crossover/PE arm.
- Point72 Asset Management: Large multi-strategy alternative asset manager with discretionary long/short, macro and private equity capabilities. Overlaps with ION on long/short equity and macro strategy structure, though at much greater scale and broader geographic mandate.
Direct peers
- Viola Group: Israeli technology-focused investment group running growth, venture and credit funds. ION Crossover Partners and Viola target the same Israeli tech growth ecosystem with similar investor base, making Viola the closest comparison for ICP's growth equity mandate.
- Altshuler Shaham: Major Israeli asset manager running mutual funds, hedge funds, pension and provident fund mandates. Comparable to ION in scale, Israeli footprint, multi-strategy structure, and institutional/HNW distribution, with strong overlap on public equity and alternative strategies.
- Platinum Asset Management: Israel-based investment manager focused on equities and alternatives. Directly comparable to ION's Israeli equity-focused long/short and tech strategies with an overlapping LP universe of Israeli institutions and family offices.
- Psagot Investment House: Israel's largest independent asset manager, distributing hedge funds, mutual funds and pension mandates to institutions and households. Directly comparable to ION as an Israeli multi-strategy asset manager serving institutional and family-office clients, with overlapping competition for allocator mandates.
- Jerusalem Venture Partners (JVP): Long-standing Israeli venture and growth investor in deep-tech and enterprise software. Comparable to ION Crossover as an Israeli-centric tech growth investor, with overlap on enterprise and cyber names like Aqua Security / Cato Networks.
- FIMI Opportunity Funds: Israel's largest homegrown private equity firm running buyout funds focused on Israeli mid-market industrial and tech companies. Directly comparable to ION Private Equity (IPE) given overlapping buyout focus on Israeli mid-market industrials, IT, and business services.
- Ansonia Holdings: New York-based long/short equity manager historically focused on telecoms and tech, including Israeli-linked names. Comparable to ION Tech Fund's public-equity tech mandate and overlap on Israeli/Israel-adjacent technology coverage.
- Arison Capital / Amar S.&S. Family-office anchored Israeli asset and investment platform running long/short and growth strategies. Comparable to ION in size, Israeli LP concentration, and mixed public/private mandate.
