Amsterdam-based cybersecurity startup Oneleet has raised $33 million in Series A funding, bringing its total capital to $35 million and positioning itself as one of Europe’s most ambitious new players in the security technology space. Founded in 2022, Oneleet is tackling one of cybersecurity’s biggest pain points: tool fragmentation. Its integrated platform aims to replace the clutter of multiple third-party vendors with a single, streamlined solution that provides attack surface management, code scanning, cloud posture monitoring, penetration testing, and compliance automation — all built and managed in-house.
The round, led by Dawn Capital with participation from Y Combinator and other investors, will fund engineering expansion, AI-driven development, and global go-to-market scaling. CEO Bryan Onel describes Oneleet’s mission as building “a single pane of glass for cybersecurity,” offering full-stack visibility and automation across code, infrastructure, and endpoint environments.
By consolidating these capabilities under one roof, Oneleet is addressing a growing industry frustration: the inefficiency and risk caused by juggling multiple security tools that rarely integrate smoothly. The platform’s ability to plug directly into cloud providers, repositories, and identity platforms enables organizations to automate protection, ensure regulatory compliance, and maintain continuous monitoring with minimal operational friction.
Oneleet’s AI roadmap stands out as a key differentiator. With end-to-end visibility across its own ecosystem, the company plans to leverage proprietary datasets to train predictive models capable of anticipating vulnerabilities before they emerge — a goal that traditional, siloed vendors can’t easily achieve.
The $33M Series A marks a milestone not only for Oneleet but for the broader cybersecurity industry, signaling a shift toward platform consolidation as companies seek simplicity, automation, and proactive defense. With its new funding, Oneleet is doubling down on the vision of a unified security stack, built to scale with the complexity of modern digital environments.
