Neo has emerged from stealth with $100 million in funding to help enterprises govern the rapid expansion of AI agents across their software environments.
The funding round was led by Andreessen Horowitz and Bessemer Venture Partners, with participation from Craft Ventures and Merlin Ventures. Neo plans to use the new capital to accelerate the expansion of its engineering and go-to-market teams as businesses increasingly focus on securing the growing adoption of agentic software.
According to the company, enterprise software environments are evolving faster than traditional security programmes can adapt. Employees are increasingly introducing new AI tools into their workflows, while established software vendors are adding agentic capabilities to applications already approved for use within corporate environments.
As a result, security operations teams are increasingly responsible for autonomous software operating inside sanctioned business applications, often without sufficient visibility or control over how those systems behave.
Neo cites Gartner research indicating that only 5% of enterprise applications had agentic capabilities in 2025. That figure is expected to rise to 40% by the end of 2026.
Traditional security architectures were designed around deterministic applications, human operators and predictable data flows. AI agents challenge these assumptions by acting autonomously, mimicking user behaviour, inheriting permissions, connecting multiple tools and moving through workflows in ways that can appear legitimate to security systems designed for earlier generations of software.
Neo’s solution is a real-time control layer designed for constantly changing software environments.
The company’s platform provides five core capabilities. Its Neoverse-powered inventory creates an overview of AI agents, AI-enabled applications, plugins, extensions, MCP servers and traditional software that has gained agentic functionality. This inventory is supported by Neo’s continuously updated knowledge base.
Its capability and risk intelligence helps organisations understand what software can do, which systems and data it can access, and whether its configuration presents security risks. Real-time attribution creates an audit trail that connects each action to the responsible human, AI agent, application or identity.
Neo also provides granular software controls that allow organisations to apply policies at the group or identity level. These policies can govern tool calls, API access, data movement and agentic workflows.
The platform also includes native enforcement capabilities, allowing organisations to block potentially dangerous activity and malicious models, as well as redirect prompts that fall outside approved boundaries without requiring a separate security tool.
Neo’s founding team brings extensive experience in cybersecurity and enterprise technology.
CEO and co-founder Nick Warner previously built SentinelOne’s go-to-market organisation and later served as its COO, helping lead the company through its 2021 public listing. His earlier experience includes senior roles at Cylance, McAfee and Forcepoint.
Co-founder Shlomi Salem led detection engineering at SentinelOne for more than a decade and co-led the company’s internal threat research unit.
Co-founder Eran Shirazi previously co-founded customer experience company EasySend and led major enterprise research and development programmes after heading vulnerability research at the IDF’s Unit 8200.
