Neo launches with $100M to secure agentic software
Former SentinelOne executives launch Neo with $100M to govern the permissions and actions of AI-enabled enterprise applications.
AI agents are turning ordinary business software into systems that can act, connect data and execute tasks. Neo is launching with an unusually large war chest to secure that new layer.
What happened
Boston-based Neo emerged from stealth with a combined $100 million seed and Series A. The company was founded by former SentinelOne executives Nick Warner and Shlomi Salem, with backing from Andreessen Horowitz, Bessemer Venture Partners, Craft Ventures and Merlin Ventures.
Neo is building security software for enterprise applications that are gaining agent-like capabilities. Its platform is designed to help companies understand what these applications can access, which actions they are allowed to perform and where those permissions create risk.
The company is entering a market where businesses are rapidly adding AI copilots and autonomous workflows to software that was originally designed for human users.
Why it matters
Traditional security models are built around people, devices and conventional applications. AI agents complicate that structure because they can move across systems, retrieve sensitive information and carry out actions without a person approving every step.
That creates a new control problem: companies need to know not only who has access, but also what an AI system can do with that access. Neo’s large launch round suggests investors expect agent governance and application-level controls to become a major cybersecurity category.
The bigger picture
As enterprises move from AI assistants to AI operators, security will need to shift from monitoring static permissions to supervising behaviour. The winners in this market may become the control layer between autonomous software and the systems it is allowed to touch.
