Gili Raanan is the founder and Managing Director of Cyberstarts, an early-stage venture fund he launched in 2018 to accelerate cybersecurity solutions, following nearly nine years as a General Partner at Sequoia Capital where he led Israeli cybersecurity investing. His investment thesis is narrowly focused exclusively on seed-stage cybersecurity companies, rejecting growth rounds and diversification into other sectors like enterprise SaaS or climate tech. Cyberstarts has raised over $720 million across five funds and made 28 investments, with the firm typically leading early rounds in this specialized niche. Notable portfolio companies include Wiz, Armis, Fireblocks, Island, Cyera, and Transmit Security, which collectively represent a portfolio valuation exceeding $55 billion. Raanan is distinguished by his background as an engineer and the inventor of CAPTCHA, a widely used security algorithm, which informs his deep technical perspective on the industry. While specific check sizes are not publicly detailed, his firm’s seed-only focus and high returns—over 100% IRR on early funds—highlight a disciplined, founder-centric approach to early cyber investing [4
