Copperhelm has emerged from stealth with $7m in seed funding and the launch of what it describes as the sector’s first agentic cloud security platform.
The round was led by TLV Partners, with additional investment from toDay Ventures, ICON, and SaaS Ventures Israel. Angel investors participating in the raise include Kfir Tishbi, Or Hiltch, Guy Zipori, and Ephraim Yarmak. As part of the announcement, Shay Michel, managing partner at Merlin Ventures, will join Copperhelm’s board of directors.
The company’s platform deploys purpose-built AI agents designed to take over manual cloud security workflows. Rather than alerting security teams and leaving them to investigate, the agents autonomously monitor cloud environments, assess threats, and carry out remediation in real time — keeping human teams in control while handling the bulk of the operational workload. The platform is aimed at CISOs and security teams at large enterprises, and the company says it already counts Fortune 500 businesses among its paying customers. In one case, a Fortune 500 client used the platform to reduce 6 million raw security findings down to a few hundred evidence-backed, validated risks that teams could realistically act on.
Central to Copperhelm’s approach is what it calls the Context Lake — a real-time decision layer that structures and connects data across cloud environments to give AI agents the contextual grounding they need to act with accuracy. The company argues that connecting a general-purpose AI model to hundreds of cloud accounts produces unreliable results due to the complexity and fragmentation of cloud infrastructure. Its agents are purpose-built for this environment, capable of analysing infrastructure across hundreds of accounts, verifying genuine risk, and executing remediation with confidence. Specialised agents cover network analysis, system behaviour, adversarial simulation, and automated remediation. They connect to live workloads, inspect active processes and container images, map cloud network topology, and deploy protections such as WAF rules to neutralise threats without causing downtime.
Copperhelm was founded by Shimon Tolts, Eyar Zilberman, and Roman Labunsky, whose collective backgrounds span Unity, McAfee, and RSA. The trio brings experience in building cloud infrastructure and security products at scale, with credentials including recognition as AWS Heroes, a CNCF Ambassador, a GitHub Star, and Y Combinator alumni status.
The $7m raised will be directed towards accelerating product development, expanding the company’s go-to-market operations, and growing its engineering team.
Copperhelm CEO and co-founder Shimon Tolts said, “Engineering teams got AI years ago; security was left behind doing manual work. Copperhelm finally brings true AI to cloud security. It’s like instantly adding twenty senior engineers to your team.”
TLV Partners co-founder and managing partner Rona Segev said, “Applying AI to cloud security requires deep architectural expertise, not just generic models with integrations. Shimon, Eyar, and Roman are true cloud veterans and the right team to bring autonomous AI into this space and shape the future of cloud defense.”
