A New Era of Secure Application Infrastructure: Why We Invested in Echo

The way modern software is built has fundamentally changed. Cloud-native development, open source dependencies, and the explosion of AI-generated code have dramatically increased the speed and complexity of application delivery. But the infrastructure supporting it all hasn’t kept up, and it’s cracking under pressure.

echo is changing that.

We’re thrilled to lead echo’s $15M Seed investment and partner with second-time founders Eilon Elhadad and Eylam Milner on their mission to make cloud-native infrastructure secure by design. Not through more scanning or overhead, but by eliminating risk at the source. 

What stood out most about echo is the founders’ clarity and conviction. Before writing a single line of code, Eilon and Eylam spent months in deep conversations with dozens of security leaders, including over 50 CISOs at Fortune 500 companies they’ve worked with for years. They weren’t validating a feature idea—they were excavating the foundation of a fractured system. They listened, mapped the pain, and built accordingly. As the founders of Argon Security (acquired by Aqua Security) and execs at the company, they’ve been in the trenches of cloud-native security and know what it takes to move the industry forward.

At the heart of echo’s platform is an AI-powered image factory that builds clean container base images from the ground up. These intelligent agents analyze each open source image and reconstruct CVE-free, minimal versions from scratch that mirror the exact functionality of the original. These images are continuously patched using intelligent backporting, ensuring they remain clean without disruptive version updates, and they’re compatible with all major Linux distributions like Ubuntu, CentOS, and Debian. Developers can easily drop echo images in using a single line of code, without needing to change workflows or tooling. 

With echo, cross-functional friction is eliminated, dashboards reflect a clean security posture, and companies have a secure foundation that scales with their infrastructure. Customers can reduce their average patch time from 30 days to under 24 hours and cut total vulnerabilities by over 99%. The platform also accelerates FedRAMP compliance with ready-to-deploy, FIPS-validated images, turning a slow, costly process into a streamlined part of the development lifecycle.

In our recent survey of security leaders, 100% said they need a solution like echo—either now or in the next six months. CISOs have budget in hand for infrastructure that’s trusted by their teams, fast to implement, and built to evolve. And with many paying enterprise customers even before launch, the demand for a solution like echo is clearly here. 

We’re proud to back Eilon, Eylam, and the incredible echo team as they build the foundation for secure-by-design infrastructure across every cloud-native environment.
