XBOW Accelerates the Expansion of its Autonomous Hacker Platform

XBOW, transforming application security with AI-powered continuous offense, led by Oege de Moor, Nico Waisman, Niroshan Rajadurai, Jonaki Egenolf, and others, has raised $120 million in Series C financing led by DFJ Growth and Northzone, valuing the company at over $1 Billion. As part of DFJ Growth’s investment, Ramin Sayar will join XBOW’s board, bringing experience to scale enterprise growth. The round also includes Sofina, Alkeon Capital, and existing investors Altimeter, NFDG Ventures, and Sequoia Capital.

As AI removes traditional constraints on attackers, threats now operate continuously at scale, while development cycles accelerate beyond the limits of human-led security testing.

“When XBOW was founded in 2024, the idea of AI thinking like a hacker at machine speed was uncertain,” said Oege de Moor. “That capability is now proven, with top rankings on HackerOne and deployments at leading security-focused companies, enabling defenders to match the speed of AI-driven attackers.”

Cybersecurity enters the autonomous era.

Security testing is shifting from periodic manual pentests to continuous, AI-driven coverage that mirrors real-world attackers. XBOW applies AI reasoning and adversarial workflows to detect and validate vulnerabilities at machine speed, uncovering deeper exploits with fewer false positives.

“XBOW proved that large language models can power offensive security at scale, combining AI reasoning with real-world adversarial expertise,” said Barry Schuler.

With adoption already underway across Fortune 500 and global enterprises, XBOW is emerging as a category leader in autonomous security, added Sanjot Malhi.

Proof achieved. Now scaling.

Over the past year, XBOW has demonstrated that autonomous security systems can operate safely in live production environments. The new funding will accelerate enterprise expansion, product innovation, and global growth.

Founded by Oege de Moor, alongside engineers from GitHub Copilot, the company combines AI systems with elite human hackers to train its “autonomous hacker” to think like real adversaries. Security leadership is reinforced by Nico Waisman, who built a world-class team to guide safe deployment.

To support scaling, XBOW has expanded its leadership with key hires across marketing, legal, revenue, and international operations, including regional expansion into South Korea.
