Why trust this list

Ranked by public deal data.

Karine Regev runs MktAccel's capital practice, which works with cyber and deeptech founders on their fundraising story and investor list. The ranking comes from public deal data, not from our preferences.

How we built it: we started from Israel Rounds' 2026 league table (rounds joined and led, 1 January to 9 November 2026, all stages and sectors). We kept funds that lead or join seed rounds in cyber or deeptech, and checked them against Velo Labs' count of 56 Israeli early-stage rounds from November 2025 to October 2026. The 2026 counts include later rounds in portfolio companies, so read them as overall activity, not seed checks alone.

What the numbers show

Three things founders should know.

Seed checks are big. TLV Partners' stated first check of $4M–$8M often covers most of a round. Below $1M, the published options are short: Fusion ($150K), Fresh Fund ($500K–$1M) and TAU Ventures (up to $1M).
Global funds come in at seed. Index Ventures joined 10 Israeli rounds in 2026, Accel 8 and Sequoia 7. Founders increasingly pair an Israeli specialist with a US fund in one seed round.
Deeptech has its own short list. Entrée, StageOne and Grove are the most active funds here that back hardware, AI infrastructure and frontier tech at seed.
