Investors rally behind Horizon3.ai's AI threat readiness platform with $100M funding
Horizon3.ai is raising $100 million to expand its AI-driven threat mitigation platform.

Cybersecurity firm Horizon3.ai is raising $100 million, with $73 million already secured per an SEC filing, signaling strong investor confidence in its AI-driven penetration testing platform.
Veteran vantage: Founded in 2019 by a team that includes former U.S. Special Operations cyber operators and ex-Splunk CTO Snehal Antani, Horizon3.ai helps organizations proactively find and fix security weaknesses. Before co-founding the company, Antani's experience included leading teams within the U.S. Military’s Joint Special Operations Command.
FedRAMP and figures: The startup recently secured FedRAMP High Authorization, opening its NodeZero platform to U.S. federal agencies. This followed a February update touting 101% year-on-year revenue growth, with one source telling TechCrunch current annual recurring revenue is around $30 million.
Capital gains: This new funding follows a $40 million Series C in August 2023, which lifted Horizon3.ai's total capital raised to $78.5 million at that point, and pushes its valuation toward $750 million, according to multiple sources. The company said those proceeds are intended to fuel growth in its R&D, channel operations, and engineering teams.
The bottom line: NEA's backing of both Horizon3.ai and identity security firm Veza points to a clear trend: investors are betting big on AI-powered platforms to combat increasingly sophisticated automated cyber threats.
Reading recap:
Meanwhile, in AI security: The broader trend shows a clear interest in companies with FedRAMP authorization, making them attractive for both investment and potential acquisition, as firms able to secure federal clients gain an edge.
