Tenzai

Tenzai is an AI-native cybersecurity company building an autonomous, agentic AI "hacker" for the enterprise. Its AI agents continuously discover, chain, and exploit hard-to-find vulnerabilities across enterprise software and validate them in production the way a human red team would, aiming to bring nation-grade offensive security to every engineering organization. Founded in 2025 by Guardicore founders Pavel Gurvich and Ariel Zeitlin together with Ofri Ziv, Itamar Tal, and Aner Mazur, the Tel Aviv-based company launched out of stealth in November 2025 with a $75M seed round (one of the largest in cybersecurity) led by Greylock Partners, Battery Ventures, and Lux Capital at a reported $330M valuation. Tenzai targets the penetration-testing market with continuous, AI-driven offensive validation. As of this profile the company exposes a marketing site, a research blog, careers, and a SOC 2 Type 1 trust center, but no public developer or API surface.
