Horizon3.ai Secures $73M, Eyes $100M Total to Advance AI Cybersecurity
Horizon3.ai, a fast-rising cybersecurity company known for its AI-driven threat detection and autonomous penetration testing tools, is raising up to $100 million in fresh funding. The company has already secured $73 million, according to a recent SEC filing.
This new round is being led by New Enterprise Associates (NEA), according to two sources familiar with the deal. The San Francisco-based startup is reportedly valued at over $750 million, though it’s unclear if that’s pre- or post-money. One insider noted that the full $100 million target is likely to be met, and that Horizon3.ai is currently generating around $30 million in annual recurring revenue (ARR).
This marks NEA’s second major investment in cybersecurity within a month, following its recent $108 million funding of Veza, which is now valued at $800 million.
Backed by Elite Cyber Experts
Founded in 2019 by Snehal Antani, a former CTO at Splunk and cyber-operator with the U.S. Special Operations Command, Horizon3.ai was built with a core team of military veterans and security specialists. Their mission: to stop automated cyberattacks using equally intelligent autonomous defenses.
In 2023, the company raised $40 million in a Series C round led by Craft Ventures, with participation from SignalFire, pushing total prior funding to $78.5 million. That round was aimed at expanding R&D, engineering talent, and partner networks.
AI-Powered Tools + Government Trust
With the rise of AI-powered cyber threats, Horizon3.ai has positioned itself as a defender against such risks. Its platform offers automated penetration testing and vulnerability scanning, helping organizations identify and neutralize risks before they become real threats.
In a significant boost, Horizon3.ai recently received FedRAMP authorization, allowing it to serve U.S. federal agencies. Earlier in February, the company also reported 101% year-over-year revenue growth and exceeded 150% of its Q4 pipeline targets, though specific figures were not disclosed.
Scaling for the Future
This latest funding will allow Horizon3.ai to expand its customer base, improve its AI-powered security capabilities, and solidify its position as one of the fastest-growing cybersecurity companies in the U.S.
As the battle between threat actors and defenders escalates, Horizon3.ai is betting that autonomous, scalable protection is the key to staying ahead.
