Novee, a Tel Aviv, Israel‑based AI offensive security startup, emerged from stealth with $51.5 million in total funding.

Backers included YL Ventures, Canaan Partners and Oren Zeev (Zeev Ventures).

The company intends to use the funds to expand operations and its development efforts.

Founded in May 2025 by Ido Geffen (CEO), Gon Chalamish (CPO) and Omer Ninburg (CTO), Novee provides an AI penetration‑testing platform to secure constantly changing environments against attackers operating at machine speed. Its purpose‑trained AI reasons like a real attacker, uncovers novel attack paths continuously, and delivers precise, personalized fixes so teams can stay one step ahead of hackers.

The company says that its proprietary AI model outperformed frontier LLMs such as Gemini 2.5 Pro and Claude 4 Sonnet by over 55 % on constrained web‑exploitation challenges, achieving up to 90 % accuracy where general‑purpose models typically plateau at around 65 %.
