Offensive security startup Novee today emerged from stealth mode with $51.5 million in funding raised over three rounds.
In May 2025, the company raised $8.5 million in seed investment. In September, it raised $33 million in Series A funding, and in December it bagged another $10 million in venture debt financing.
The startup has built an AI-driven penetration testing platform that enables businesses to uncover novel vulnerabilities through simulating real-world hacking tactics.
The platform, Novee says, can uncover complex business logic flaws and offers exploit validation and automated retesting, in an end-to-end loop that ensures critical issues are completely addressed.
Specifically designed for offensive security, Novee’s proprietary AI model is trained on real-world attack techniques, tools and workflows.
By reasoning like a real-world hacker, the solution continuously looks for novel attack paths to deliver personalized fixes.
According to Novee, its platform is amplifying human pentesters by handling the testing across all assets and allowing the security teams to focus on more sophisticated operations.
The company is now looking to expand its solution into a full offensive security platform that would cover infrastructure, cloud, mobile application, AI application, and other types of penetration testing.
Novee has offices in Tel Aviv and New York City and says it is serving mid-size and large enterprises.
The company was founded in May 2025 by Israeli army offensive cyber veterans Ido Geffen (CEO), Gon Chalamish (CPO) and Omer Ninburg (CTO). It has 32 employees, including multiple Talpiot graduates, IDF cyber veterans, and renowned bug bounty and vulnerability researchers.
“Novee is built by a team that has spent decades operating at the highest levels of offensive cyber and critical infrastructure defense. They understand how real attackers think because they have done this work themselves, at scale and under real-world constraints,” YL Ventures managing partner Yoav Leitersdorf said.
