ION Crossover Partners

Jonathan Kolber and Gilad Shany, the firm's co-founders and Managing Partners, jointly lead investment decisions. Kolber's background includes a partnership at Israel Growth Partners, where he spent over a decade investing across the Israeli technology landscape. The firm operates with a lean senior team, meaning most investment committee decisions involve the two managing partners directly.

ION's sourcing advantage comes from its physical presence in Herzliya and its partners' multi-decade networks across Israeli technology. Unlike visiting crossover funds from the US, ION maintains continuous engagement with Israeli founders, venture investors, and investment banks that underwrite local IPOs. The firm's concentration on Israel-only deals means it competes on relationship depth rather than speed of term sheet issuance.

ION operates as a dedicated crossover fund, not a traditional venture capital firm. The firm targets companies that have already achieved significant revenue scale — typically $30M to $100M in ARR — and are within 12 to 24 months of a liquidity event. Unlike venture firms that lead Series A and B rounds, ION enters at the pre-IPO stage and frequently holds positions through public listing, behaving like a crossover investor with a growth-equity entry point.

ION deploys capital almost exclusively through direct equity investments in late-stage private companies. The firm does not publicly operate a fund-of-funds program or make commitments to other venture capital or private equity managers. The concentrated nature of its portfolio — often fewer than 15 positions — reinforces the direct-investment model.

ION concentrates on enterprise-facing technology companies and has not disclosed investments in consumer-facing marketplaces outside of select insurtech positions like Lemonade. The firm does not invest in hardware, semiconductors, or deep-tech verticals such as quantum computing or aerospace. Its deal history shows no exposure to ad-tech beyond the ironSource position, which was held prior to its acquisition by Unity.

ION's portfolio includes several companies that completed initial public offerings or high-profile M&A events. Riskified listed on the New York Stock Exchange in 2021. WalkMe went public on Nasdaq in 2021 before its acquisition by SAP in 2024. ironSource listed via SPAC in 2021 and was later acquired by Unity. Lemonade completed its NYSE IPO in 2020. The firm's strategy of holding through the listing means returns are correlated with post-IPO stock performance.

Most Israeli growth-stage managers — such as Qumra Capital or Viola Growth — operate as traditional late-stage venture funds that exit before or at IPO. ION explicitly positions itself as a crossover vehicle, meaning it competes with global crossover giants like Tiger Global and Dragoneer rather than local venture peers. This crossover posture changes ION's holding period, diligence lens, and relationship with public-market investors who buy shares post-listing.
