Horizon3.ai Series E

Cybersecurity startup Horizon3.ai has secured a $250 million Series E funding round at a $2 billion valuation, more than tripling its valuation in 14 months. This round, led by returning investors NightDragon and NEA, comes as the company reported approaching $100 million in annual recurring revenue with 120% year-over-year growth last year. Horizon3 plans to leverage these funds to further develop its AI-powered continuous security validation platform, NodeZero, amidst escalating AI-driven cyber threats.
