Neo has emerged from stealth with $100m in funding to help enterprises govern the rapid spread of AI agents across their software estates.
The round was led by Andreessen Horowitz and Bessemer Venture Partners, with Craft Ventures and Merlin Ventures also taking part. The fresh capital will be channelled into an aggressive expansion of Neo’s engineering and go-to-market functions, as businesses race to lock down security around fast-growing agentic software adoption.
The company argues that enterprise environments are transforming more quickly than legacy security programmes can keep pace with. Staff are bringing in new AI tools from the ground up, while incumbent vendors are layering agentic features into applications that already sit inside approved corporate stacks.
This leaves SecOps teams responsible for autonomous software running within sanctioned business tools, frequently without the oversight required to police its behaviour. Gartner figures cited by the firm show that just 5% of enterprise applications carried agentic capabilities in 2025, a figure expected to hit 40% by the close of 2026.
Older security architectures assumed deterministic applications, human operators and predictable data flows. Agentic systems break those assumptions, acting on their own initiative, imitating user behaviour, inheriting permissions, chaining tools together and traversing workflows in ways that look legitimate to defences designed for earlier software generations.
Neo’s answer is a real-time control layer for shifting software stacks. Its platform delivers five core capabilities. A Neoverse-powered inventory catalogues AI agents, AI-enabled applications, plugins, extensions, MCP servers and traditional software gaining agentic functions, drawing on Neo’s continuously refreshed knowledge base.
Capability and risk intelligence reveals what software can do, what it can reach and whether its configuration is safe. Real-time attribution produces an audit trail linking every action to the responsible human, agent, application or identity. Granular software control lets organisations apply group- or identity-level policies covering tool calls, API access, data movement and agentic workflows.
Finally, native enforcement allows firms to block dangerous activity and malicious models, and redirect out-of-bound prompts, without relying on a separate tool.
The founding team brings substantial cybersecurity pedigree. CEO and co-founder Nick Warner built SentinelOne’s go-to-market organisation and, as COO, steered the firm through its 2021 public listing, following senior positions at Cylance, McAfee and Forcepoint.
Co-founder Shlomi Salem ran detection engineering at SentinelOne for over a decade and co-led its internal threat research unit. Co-founder Eran Shirazi previously co-founded customer experience business EasySend and led major enterprise R&D programmes after heading vulnerability research at the IDF’s Unit 8200.
Neo CEO and co-founder Nick Warner said, “Enterprise security was built for a world where software behaved predictably. That world is changing fast. AI agents and agentic capabilities are being embedded into browsers, developer tools, SaaS platforms, and traditional applications, giving software the ability to reason, act, invoke tools, and move through workflows with valid user permissions. Neo gives enterprises the real-time control layer they need to understand what agentic software can do, govern how it behaves, and secure adoption without slowing down the business.”
