Cybersecurity startup Echo has raised $15 million in seed funding to build secure-by-design infrastructure for modern applications. The round was led by Notable Capital and Hyperwise Ventures, with participation from SVCI. Echo’s founding team, Eilon Elhadad and Eylam Milner—both alumni of Israel’s elite Unit 8200 and previously co-founders of Argon (acquired by Aqua Security for $100M)—aim to eliminate software vulnerabilities at the source using AI.
Rethinking Vulnerability Management
Unlike most cybersecurity platforms that detect and prioritize known vulnerabilities, Echo’s technology proactively rebuilds open-source components using AI agents. These agents analyze functionality, strip out flaws, and continuously patch as new threats emerge. This creates a hardened foundation for running containers securely—preventing issues before they materialize.
With software development accelerating through AI, traditional reactive models struggle to scale. Industry reports cite a 61% surge in new vulnerabilities and a 34% rise in exploit attempts this year alone. Echo’s preventative approach stands out by targeting the root cause of risk rather than managing its symptoms.
Enterprise Traction and Industry Alignment
Echo's platform is already in use by organizations like Vectra AI, Port, UiPath, and Varonis, and integrates with leading security vendors such as Wiz, Orca, Aqua, Mend, and Anchor. The company currently employs 25 people across Israel and New York and will use the new capital to expand its engineering team, accelerate product development, and scale go-to-market operations.
“Today’s tools rank thousands of issues. We’re rewriting code so those issues don’t exist,” said CEO Elhadad. “The market has been forced to accept risk as a byproduct of speed—Echo changes that.”
Market Opportunity
The vulnerability management industry is valued at $17 billion, but as Notable Capital’s Oren Junger notes, Echo is unlocking a path to significantly reduce both operational costs and breach fallout by delivering infrastructure that’s secure by design.
Echo enters a crowded but growing space, competing with incumbents like CrowdStrike and Palo Alto Networks, but its AI-driven rebuild model offers a radically different security posture—designed for the software velocity of today’s AI era.
