XBOW has closed a $35M Series C extension round led by NVIDIA, Samsung, Accenture, and SentinelOne, bringing its total Series C to $155M.
The company is valued at over $1 billion, and its total funding exceeds $270M.
XBOW was founded by Oege de Moor, the engineer who created GitHub Copilot, one of the most widely used AI coding tools in the world.
Seattle-based XBOW has raised an additional $35 million in a Series C extension, bringing its total Series C to $155 million and its overall funding to more than $270 million.
The round was backed by a group of strategic investors, including Accenture Ventures, DNX Ventures, Liberty Global Tech Ventures, NVentures, Samsung Ventures, and SentinelOne S Ventures, several of whom are also active users of the platform.
Founded in 2024 by Oege de Moor, the engineer who created GitHub Copilot, Microsoft’s AI coding assistant used by millions of developers, XBOW builds software that finds security weaknesses in applications the way a real attacker would.
Instead of relying on traditional penetration tests conducted by human teams at fixed intervals, the platform runs continuously, probing systems around the clock and validating whether vulnerabilities can be exploited.
The company now serves more than 100 customers globally, including Moderna and Seznam. Competitors in the autonomous security testing space are Pentera and Node.js-based platforms like Cobalt, but XBOW’s continuous validation approach and its founder’s profile set it apart.
The company has grown to more than 250 employees and is continuing to hire across engineering, go-to-market, and operations. The fresh capital will fund XBOW’s international expansion, with a particular focus on the Asia-Pacific region.
