San Francisco-based Horizon3.ai is in the process of raising a $100 million funding round, having already secured at least $73 million, according to a recent SEC filing.
The round is reportedly led by NEA, marking the firm’s second major cybersecurity investment this quarter after backing Veza’s $108 million round.
Growth signals and FedRAMP approval
Founded in 2019 by Snehal Antani—former Splunk CTO and U.S. military cyber operator—Horizon3.ai develops autonomous penetration testing and threat detection software. The company, which has surpassed $30 million in annual recurring revenue, recently received FedRAMP authorization, allowing it to serve U.S. federal agencies.

Investor confidence and market momentum
Valuation discussions place the company at over $750 million, though it’s unclear whether that figure is pre- or post-money. Horizon3.ai last raised $40 million in a Series C led by Craft Ventures in 2023, which brought its total raised to $78.5 million at the time. It also boasts 101% YoY revenue growth and surpassed 150% of Q4 sales pipeline goals earlier this year.
The ongoing $100 million round is expected to fuel further growth in a cybersecurity landscape increasingly shaped by AI-driven threats—and the tools to defend against them.
