A former teen hacker turned cybersecurity expert has secured a significant funding round to develop advanced AI solutions aimed at thwarting sophisticated phishing threats.
Eliav Cohen, the founder of Ocean, an agentic email security platform, has raised $28 million in a Series A funding round led by Insight Partners. The investment underscores growing market demand for robust defenses against AI-driven phishing attacks, which are becoming increasingly prevalent and sophisticated. Cohen’s journey from a teenage hacker to a leading cybersecurity researcher highlights the evolving landscape of digital threats and the innovative solutions required to combat them.
Cohen's background is as unique as it is compelling. As a teenager, he was known for his hacking skills, but over the years, he transformed this expertise into a force for good. He became a prominent researcher at Iron Dome, where he focused on developing advanced cybersecurity technologies. This experience laid the foundation for Ocean, which aims to use AI to thoroughly analyze the context of every incoming email, detecting fraud and impersonation attempts with high accuracy.
The rise of AI in phishing attacks has created new challenges for businesses and individuals alike. Traditional security measures are often insufficient against these sophisticated threats, which can bypass conventional detection methods. Cohen’s platform leverages machine learning to identify subtle patterns and anomalies that human analysts might miss, providing a more comprehensive defense.
According to recent studies, the cost of phishing attacks is projected to reach $10 billion by 2026, up from $3.8 billion in 2021. The financial impact on businesses can be severe, including direct monetary losses, reputational damage, and operational disruptions. Ocean’s AI-driven approach offers a proactive solution that could significantly reduce these risks.

The $28 million funding round is a strong endorsement of Cohen’s vision and the potential of Ocean’s technology. Insight Partners, known for its strategic investments in high-growth technology companies, sees significant market opportunity in this space. The firm’s involvement not only provides financial resources but also valuable industry connections and expertise.
For investors, the cybersecurity sector remains a promising area with strong growth prospects. According to Gartner, global spending on information security and risk management is expected to exceed $172 billion by 2025. Ocean’s innovative approach to email security aligns well with this trend, positioning it as a potential leader in the market.
The funding will be used to accelerate product development, expand the team, and enhance marketing efforts. Cohen plans to integrate additional AI capabilities and improve user experience, making the platform more accessible to businesses of all sizes. As phishing attacks continue to evolve, Ocean’s ability to adapt and stay ahead of emerging threats will be crucial for its long-term success.
Eliav Cohen’s journey from a teen hacker to a cybersecurity entrepreneur is a testament to the transformative power of technology. With significant financial backing and a clear mission, Ocean is well-positioned to make a meaningful impact in the fight against AI-driven phishing attacks. Investors and businesses alike should keep an eye on this promising startup as it navigates the rapidly changing landscape of digital security.

About the author
Marcus began tracking AI's market implications in 2016, noticing AI-related patent filings accelerating ahead of earnings upgrades before most of the sell-side had caught on. A former fixed-income quantitative analyst, he spent two decades building models that priced risk across emerging markets before pivoting to cover the economic impact of AI full-time. His writing translates opaque technical developments into clear risk/reward terms — and he's rarely diplomatic about the gap between AI valuations and underlying fundamentals. He believes most market participants still underestimate AI's long-run deflationary effect on knowledge work.
