Horizon3.ai Secures $100M Funding to Expand AI-Powered Cybersecurity Solutions

San Francisco-based cybersecurity startup Horizon3.ai is raising $100 million in a new funding round, with at least $73 million already secured, according to a recent SEC filing.

The round is being led by NEA(New Enterprise Associates), marking its second big cybersecurity investment this month, following Veza’s $108 million raise.

Founded in 2019, Horizon3.ai offers autonomous penetration testing and AI-powered threat detection tools. The company is known for its team of former U.S. Special Operations cyber experts and experienced tech leaders, including co-founder and CEO Snehal Antani, who was previously the CTO at Splunk.

According to a source, the company’s worth more than $750 million, with around $30 million in recurring revenue. In August 2023, Horizon3.ai raised $40 million in a Series C round led by Craft Ventures, bringing total funding to $78.5 million before this latest round.

The new funding aims to accelerate product development, expand the engineering team, and grow its federal business — especially after recently achieving FedRAMP authorization. The company also reported over 100% year-on-year revenue growth and surpassed 150% of its Q4 pipeline targets.

As AI-driven cyberattacks continue to rise, Horizon3.ai is positioning itself as a leader in next-gen cybersecurity with autonomous solutions that help businesses stay ahead of evolving threats.
