Eve Security raises $4.5M extension to seed round targeting malicious AI agents

Led by Run Ventures with Dreamit, Blu and LiveOak Ventures participating, the round lifts the runtime security startup's seed total to $7.5 million.

Eve Security Inc., a startup focused on runtime security for artificial intelligence, has secured $4.5 million in new capital to advance its mission of halting AI agents that turn dangerous while in operation. Announced Tuesday, the round was led by Run Ventures, with Dreamit Ventures, Blu Ventures and LiveOak Ventures all taking part. The injection lifts the company's total seed funding to $7.5 million.

The company's premise is that intervention must occur while an agent is actively running. Rather than screening models or prompts ahead of deployment, runtime security is designed to catch a misbehaving or malicious agent at the point of execution — in effect stopping it mid-flight before an action can be carried out to completion. Eve Security is building around that window, where the risk posed by agentic systems is at its most immediate.

The fresh $4.5 million sits on top of capital already raised, pushing Eve Security's seed round to $7.5 million overall. The structure — an extension rather than a new financing stage — suggests continued investor conviction, with Run Ventures taking the lead position and three additional firms, Dreamit Ventures, Blu Ventures and LiveOak Ventures, joining the syndicate. For seed investors, the thesis is that agent security is becoming a required control as organizations weigh how much autonomy to grant AI systems.

Agent-based systems have shifted from demonstrations to real enterprise workflows, exposing execution-time risks that perimeter and endpoint defenses were not built to address. For AI buyers and infrastructure teams, Eve Security's enlarged seed war chest is a signal that the runtime defense layer is starting to draw early institutional money. Whether the startup can translate that backing into tooling enterprises trust enough to place inline with their agents will define what this round was ultimately worth.
