Exclusive: Horizon3.ai raises $100M Series D
Autonomous security startup locked up a $100 million Series D led by NEA, co-founder and CEO Snehal Antani tells Axios Pro. Why it matters: AI is making cyberattacks faster and more sophisticated — and is aiming to even the playing field. How it works: penetration testing platform — NodeZero — uses AI to find and exploit attack paths in production systems so teams can fix issues. The platform also collects training data used to improve its own algorithms and increase defenses. Zoom in: SignalFire, Craft Ventures and 9Yards Capital also participated in the round, which brings the company's total funding to $180 million. By the numbers: is experiencing 100% ARR growth year to year and is now Rule of 40-positive. The startup's platform is used by 3,000 organizations — including national defense partners — and is more than doubling its customer base annually. State of play: The penetration testing market seems to be attracting investors. Strike Security raised a $13.5 million Series A led by FinTech Collective in March. Threat level: A recent survey found that almost 74% of participants say AI-powered threats are a major challenge for their company.

Horizon3.ai Raises $100M to Cement Leadership in Autonomous Security
San Francisco, United States: , the company behind the NodeZero® Autonomous Security Platform, today announced a $100 million Series D funding round led by NEA, with participation from SignalFire, Craft Ventures and 9Yards Capital. As part of the investment, Lila Tretikov, Partner and Head of AI Strategy at NEA and former Deputy CTO of Microsoft, will join the Board of Directors. 'Over the past four years, we've proven that using AI to hack companies isn't science fiction—it's real, and it's delivering measurable results at scale. There are now over 3,000 organizations using NodeZero globally to conduct penetration tests. We're sustaining 100%+ year-over-year ARR growth, and we are now Rule of 40-positive, which means we're not just growing—we're growing efficiently,' said Snehal Antani, CEO and Co-founder of 'This raise marks the next chapter in our mission to lead the Autonomous Security category.' 'Security teams are tired of chasing CVEs, false positives, and compliance checkboxes. They want to find and fix what actually matters, verify it's resolved, and go home early,' said Antani. 'The hardest part of the job as a CIO is deciding what not to fix. The second hardest part is proving to the board that your security initiatives are meaningfully reducing risk. NodeZero plays a critical role in reducing your threat exposure over time.' Targeting an $80B Total Addressable Market: Autonomous Security The cybersecurity market is undergoing a generational shift. NodeZero successfully compromised a bank in 4 minutes with no humans required, far faster than the reaction time of the bank's security team and their best-in-class tools. Similarly, adversaries are leveraging AI to exponentially increase the sophistication, complexity, speed and scale of attacks. The thesis is simple: the future of cyber will be algorithms fighting algorithms—at machine speed—with humans by exception. This requires a fundamental rebuild of every part of the cybersecurity stack. And to do so effectively, you need a deep understanding of how attackers operate—and an AI system that can use offensive insights to drive defensive improvements. is leading this shift. ' has already realized what others are just beginning to imagine. NodeZero is a fully autonomous security system operating in live production environments—executing real attacks, uncovering real risk, and delivering real results,' said Antani. Powered by reinforcement learning, graph reasoning, and AI, NodeZero doesn't simulate adversaries—it thinks and acts like one. Each cyber attack against production systems executed by NodeZero collects training data used to improve its algorithms, creating a compounding data advantage that no other platform can match. This is the foundation for the next era of cybersecurity, where AI doesn't just find risk, but continuously improves defenses. isn't chasing the future—it's building it. Use of Proceeds: Accelerating Toward the Future With this funding, Horizon3 is accelerating across three strategic fronts: Scale through partners – Doubling down on its partner ecosystem to meet growing demand across the Americas, EMEA, and APAC. – Doubling down on its partner ecosystem to meet growing demand across the Americas, EMEA, and APAC.

Winning the federal market – Scaling its success with the Defense Industrial Base through the NSA's Continuous Autonomous Pentesting (CAPT) program, accelerating FedRAMP High usage, and expanding into Secret and Top Secret workloads to help secure the nation's most mission-critical systems. 'What drew us to is the clarity of their mission and the speed at which they're executing it,' saidAaron Jacobson, Partner at NEA. 'They are defining a new security category—autonomous security—and are already the go-to solution for red and blue teams alike. We're thrilled to lead this round and support the company's next phase of growth.' 'Snehal and the team are tackling one of the biggest problems in cybersecurity: automating both sides to ensure maximum defensibility against automated and AI-driven attacks,' said Lila Tretikov, Partner and Head of AI Strategy at NEA. 'Their customers love NodeZero, and the team has proven to operate with excellence at scale, which is why is transforming how security is done. I'm excited to join the board and help shape this next chapter.' The impact is immediate and measurable. In one recent pentest, NodeZero gained access to sensitive US aircraft carrier design data through a third-party supplier. No humans were involved in the pentest. The platform autonomously compromised the network, gained access to sensitive data, and then guided defenders on exactly what to fix to prevent a breach. 'My old boss used to say, 'don't tell me we're secure, show me, then show me again tomorrow, and again next week, because our environment is always changing and the enemy always has a vote,'' said Antani.
