Horizon3.ai is currently seeking new funding. The cybersecurity startup aims to raise $100 million. It has already secured at least $73 million. This was revealed in an SEC filing this week. Venture capital firm NEA reportedly led this new funding round. The startup’s valuation is believed to be quite high. It is estimated to be upward of $750 million. Some sources believe the full $100 million will be sold. The company currently generates about $30 million in annual recurring revenue. Horizon3.ai and NEA have not yet commented publicly.
This deal marks NEA’s second recent major cybersecurity investment. They also invested in the startup Veza in April. Veza raised $108 million in that funding round. Horizon3.ai itself previously raised $40 million. This was its Series C funding round in August 2023. Craft Ventures led that particular investment round. SignalFire also participated in the Series C then. That earlier round brought its total fundraising to $78.5 million. Those funds aimed to expand research and development efforts. They also planned to grow their engineering team significantly.
Horizon3.ai was founded in the year 2019. Its core team possesses a unique, strong background. It includes former U.S. Special Operations cyber operators. Experienced entrepreneurs and cybersecurity experts are also part of it. Co-founder and CEO Snehal Antani has notable prior experience. He previously served as the CTO at Splunk. He also led specialized teams within U.S. military special operations. The San Francisco-based startup focuses on emerging AI threats. AI-powered automated cyberattacks are currently on the rise globally. Horizon3.ai provides autonomous threat detection tools. These tools help organizations protect against such advanced attacks.
The company achieved important FedRAMP authorization recently. This significant milestone occurred earlier this month, in May 2025. This authorization allows sales of its products to federal agencies. This development opens up a substantial new market. Horizon3.ai also announced very strong growth in February. It reported 101% year-on-year revenue growth. The company exceeded 150% of its Q4 pipeline targets. However, specific detailed financial numbers were not shared publicly. These recent achievements clearly show positive company momentum. This new funding will likely fuel even further expansion.
