Novee is a cybersecurity startup that has raised $51.5 million in Seed and Series A funding within just four months. The funding rounds were led by YL Ventures, Canaan Partners, and investor Oren Zeev through Zeev Ventures.
The company is building an AI-powered platform that helps protect organisations using advanced cybersecurity techniques usually used in hacking and cyber-attack testing.
Novee works in the same cybersecurity space as Tenzai, another company that recently raised $75 million.
Novee was founded in May 2025 by Ido Geffen (CEO), Gon Chalamish (CPO), and Omer Ninburg (CTO). All three are experienced cybersecurity professionals.
They previously worked in top Israeli government and military cyber units, including Unit 8200, the Talpiot program, and special teams linked to the Prime Minister’s Office, where they handled advanced cyber operations.
The Novee team also includes experts who have worked on national cyber defence, including a former leader of Israel’s Red Team that protected major systems like Iron Dome, and specialists in cyber and AI security.
Gefen said the speed of the fundraising reflected both market demand and the company’s technical approach. “I’ve been involved in several startups, including Orca and Oasis,” he said. “We raised our Seed round with YL Ventures and Canaan Partners in May, and within three to four months we closed a Series A.”
Gefen said the founders’ experience in uncovering security vulnerabilities, particularly in applications, led them to identify what he described as a persistent gap in the market. “Until now, this work has largely been done manually,” he said. “Automated tools don’t perform at a sufficiently high level, and many existing solutions fail in real-world conditions.”
According to Gefen, Novee trains its own proprietary model, enabling it to detect complex breaches embedded in an organization’s business logic. “We don’t just identify problems, we help solve them,” he said. “That combination is difficult to replicate. We are a cybersecurity company, but we are also very much an AI company.”
Cyber threats are changing as attackers now use AI to automatically collect information, scan systems all the time, and find weaknesses much faster than traditional security tools can handle.
However, security testing in most companies is still done only occasionally, manually, or with limited automation, making it harder to keep up with these fast-moving threats.
