Echo Raises $35 Million Series A to Build AI‑Native, Vulnerability‑Free Cloud Infrastructure
Echo, the New York and Tel Aviv‑based AI‑powered secure software infrastructure startup, has raised a $35 million Series A funding round, bringing its total fundraising to approximately $50 million in just ten months since its launch. The investment marks a major vote of confidence in the company’s mission to build an AI‑native operating system that delivers secure, vulnerability‑free container base images for cloud applications — a foundational need for modern enterprise infrastructure.
The $35 million Series A was led by N47, a global venture capital firm focused on early‑stage enterprise technology companies. Participation in the round came from existing backers Notable Capital and Hyperwise Ventures, both of which also supported Echo’s earlier seed round, as well as SentinelOne’s S Ventures, the strategic investment arm of cybersecurity firm SentinelOne. This investor mix combines enterprise software and security expertise with strategic backing from a major cybersecurity player, giving Echo a solid foundation to scale its technology and market reach.
Echo was co‑founded in early 2025 by Eilon Elhadad and Eylam Milner, veterans of Israel’s elite 8200 technology unit with deep experience in cybersecurity and cloud infrastructure. The company’s core product uses purpose‑built AI agents to autonomously generate container base images from scratch that are free of known vulnerabilities — eliminating risks before workloads are deployed in production. Rather than patch vulnerable open‑source images, the AI‑driven system continuously maintains hardened images, researching new vulnerabilities, developing fixes and applying updates automatically, a process that traditional methods struggle to keep pace with.
The Series A funding comes just months after Echo’s $15 million seed round, which was led by Notable Capital and Hyperwise Ventures with support from SVCI. That initial capital was aimed at building the company’s secure infrastructure platform and enabling broader deployment of its vulnerability‑free container images across enterprise environments. The rapid succession of these funding rounds underscores strong investor belief in Echo’s technology and the escalating demand for proactive security solutions in cloud‑native environments.
Echo’s infrastructure is already being used to secure workloads for enterprise customers across multiple industries, with high‑profile users including Varonis, EDB and UiPath. The company’s approach responds to a pervasive challenge in modern software development: most container base images, such as standard Docker stacks like Python, Node.js and Go, contain hundreds or thousands of known vulnerabilities that organizations inherit before writing any code. Echo’s AI‑native system effectively replaces these images with clean, secure equivalents, reducing the attack surface and enabling secure‑by‑design application deployment.
The company plans to use the Series A funding to expand its development and engineering teams, refine its AI and automation capabilities, and accelerate adoption of its secure operating system by enterprise customers. Echo executives have described the capital as critical to scaling operations and broadening the reach of their platform as more organizations seek security solutions that can keep pace with the rapid evolution of cloud technologies and AI‑driven development practices.
Demand for robust cloud security solutions continues to grow as enterprises rely increasingly on containerized applications and distributed architectures. Traditional vulnerability management tools often struggle to keep up with the sheer volume of emerging threats and open‑source components in modern software stacks. Echo’s preventive model — which eliminates vulnerabilities at the source — represents a shift in strategy from reactive detection and patching to proactive risk removal. Investors in the Series A round have emphasized this strategic distinction as a key reason for their backing.
Industry analysts see Echo’s rapid growth and substantial funding as indicative of broader trends in cloud security and AI integration. As enterprises navigate complex security landscapes, solutions that automate threat mitigation while maintaining compliance and performance are in high demand. Echo’s AI‑native infrastructure not only strengthens security postures but also positions the company at the intersection of two major tech waves: AI‑powered automation and secure cloud computing.
With its strengthened investor base, expanding customer roster and momentum from back‑to‑back funding rounds, Echo is poised to accelerate the adoption of secure, vulnerability‑free infrastructure across enterprise environments, redefining how organizations build and deploy cloud applications in an increasingly digital and threat‑dense world.
