The round was led by Dawn Capital, with additional support from Y Combinator and several angel investors, and it will help the Amsterdam-based cybersecurity startup to expand its engineering team, invest further in AI capabilities, and scale its go-to-market efforts.

Founded in 2022, Oneleet provides a platform that combines attack surface management with code scanning to identify forgotten assets, exposed services, and vulnerabilities before production, while also offering penetration testing and audit preparation. The company says its solution connects with existing stacks, enabling policy management, risk tracking, vendor discovery, and automated compliance across cloud providers, repositories, identity platforms, and productivity tools.
