Echo Raises $35 Million in Series A Funding

Echo today announced raising $35 million in a Series A funding round that brings the total raised by the company to $50 million, according to SecurityWeek. The round was led by N47, with additional support from Notable Capital, Hyperwise Ventures, and SentinelOne’s S Ventures. Tel Aviv-based Echo uses AI agents to build Docker images that eliminate vulnerabilities at the source, stripping open source images of non-essential components to reduce the attack surface while maintaining functionality.

Echo’s CVE-free container base images are designed as drop-in replacements for standard Docker images, and the company says they can be used by modifying a single line of code in Dockerfile. The firm was founded in 2025 by Eilon Elhadad and Eylam Milner, who also founded Aqua Security-acquired Argon, and previously raised $15 million in seed funding this summer.
