Investment Thesis

“Focuses exclusively on early-stage cybersecurity startups, providing hands-on support to build category-defining security companies.”

Leadership Team

Gili Raanan is the founder and is the sole named director on every Cyberstarts fund Form D from 2018 through 2025. The bench listed on the firm's site is Raanan, Lior Simon, Pete Chronis, Hila Zigman, Adam Aarons and Dor Knafo.

Cyberstarts positions itself as a day-one partner rather than a conventional seed fund. Its stated method is a systematic process for surfacing the most urgent unsolved problems in cybersecurity, validated through an extensive network of chief information security officers before a company is built, which it credits for rapid product-market fit. It also selects for management teams that have faced significant adversity. The firm hosts Cybersparx, a Miami gathering for security operators launched in 2025 with more than 200 attendees, as a channel for that CISO network.

A Form D is the notice a fund files with the SEC when it raises money in a private offering. Feeder funds, parallel funds and SPVs each file their own, so the count measures filing activity, not the number of flagship funds.

Vehicles are matched to Cyberstarts by fund name and checked against the sponsor address and named principals on each filing; offering amounts are not shown.
