Ocean, an agentic email security platform, secured $28M in funding led by Lightspeed Venture Partners. The startup targets AI-powered phishing attacks with technology developed by a founder with backgrounds in both cybersecurity and defense systems.

Ocean addresses a growing threat: phishing attacks enhanced by artificial intelligence. The platform uses agentic technology—autonomous AI systems that take independent action—to detect and neutralize email-based threats. The startup's founder brings uncommon credentials to the problem. A former teen hacker, they later worked on Iron Dome, Israel's air defense system, before turning to commercial cybersecurity. Email remains a primary attack vector for enterprises. Traditional security tools struggle against AI-generated phishing content that mimics legitimate communications. Ocean's agentic approach aims to match sophistication with sophistication, autonomously analyzing and blocking threats. Lightspeed Venture Partners led the round, signaling investor confidence in the company's approach. The funding positions Ocean to expand its team and product capabilities as phishing attacks grow more sophisticated.
