The officials and investors of Xbow have confirmed that the AI security start-up has reached a valuation of more than $1 billion following its latest funding round, giving the company “unicorn” status.
The Washington-based cybersecurity company raised $120 million in a Series C financing round. The round was led by DFJ Growth and Northzone, with participation from new investors Alkeon Capital and Sofina, as well as existing backers including Sequoia Capital, Altimeter Capital, and NFDG Ventures. The fresh capital will be used to accelerate product development, expand enterprise sales, and support international growth amid rising demand for AI-driven security solutions.
Xbow’s technology leverages large-scale artificial intelligence to automate the detection and remediation of software vulnerabilities, supplementing traditional manual security testing. The company describes this approach as autonomous offensive security, enabling organisations to continuously probe applications for weaknesses at machine speed.
Founder and Chief Executive Officer Oege de Moor said the company’s tools are already deployed in enterprise environments, helping clients identify and address vulnerabilities more efficiently. “Our AI thinks like a hacker but works at machine speed, helping defenders stay ahead of evolving cyber threats,” Moor said.
Industry experts note that AI-driven security solutions are increasingly critical as cyber threats grow more sophisticated and software delivery cycles accelerate. Xbow’s valuation reflects growing investor confidence in technologies capable of delivering automated, scalable, and comprehensive cybersecurity protection.
