XBOW has raised $35m in an extension to its Series C round, with the fresh capital coming from a group of strategic investors that includes several of the firm’s own customers and ecosystem partners.
The extension was backed by Accenture Ventures, DNX Ventures, Liberty Global Tech Ventures, NVentures (NVIDIA’s venture capital arm), Samsung Ventures and SentinelOne S Ventures.
The raise builds on XBOW’s previously announced $120m Series C and signals a notable trend: large enterprises are not merely deploying the platform, but committing capital to it as they look to defend against increasingly sophisticated, AI-driven threats.
XBOW currently counts more than 100 customers across the world, including some of the strategic investors in this round, as well as industry names such as Moderna and Seznam. The company recently passed 250 employees and is continuing to scale across its go-to-market, engineering and operations functions to keep pace with growing enterprise demand.
The new funding will be used to accelerate XBOW’s international growth strategy. Through DNX Ventures’ regional expertise and networks across Asia Pacific, and Samsung’s role as a preferred reseller in South Korea, XBOW is broadening its distribution channels and partner ecosystem to drive adoption in that market.
XBOW’s platform uses AI to continuously identify and exploit vulnerabilities in applications in the same manner as a real-world attacker would, rather than conducting one-off point-in-time penetration tests. It produces validated findings with a low false-positive rate, and is also capable of confirming the exploitability of issues flagged by other security tools, helping security teams focus on genuine threats rather than noise. As software development cycles accelerate, continuous offensive testing is becoming a foundational element of enterprise security operations, with XBOW positioning itself as a way for organisations to proactively stay ahead of adversaries rather than responding to them after the fact.
XBOW founder and CEO Oege de Moor said, “We’re learning in real time from teams operating at massive scale, and using that insight to build faster for defenders on the front lines. The strongest alignment is when your customers are also in the trenches with you as investors and partners.”
SentinelOne director of corporate development and ventures Alex Krongold said, “The attacker’s point of view is foundational to defense, but difficult to operationalize. XBOW changes this by surfacing exploitable and novel findings at machine speed. Each XBOW agent operates like an extension of our in-house red team, allowing us to scale offensive testing with speed and depth that was previously out of reach.”
A Samsung Ventures America representative said, “We’re seeing accelerating demand for XBOW as organizations look for continuous, intelligent security testing. As a customer, we’ve experienced the platform’s ability to surface real-world risks with speed and precision. XBOW stands out in a crowded market, and we’re excited to now back this talented team as both a partner and investor.”
