American-Israeli cybersecurity startup Neo emerged from stealth mode on Monday with $100 million in funding for a platform that enables enterprises to control and secure AI software.
Neo received the investment across seed and Series A funding rounds from Andreessen Horowitz, Bessemer Venture Partners, Craft Ventures, and Merlin Ventures. The company will use the money to grow its engineering and go-to-market teams.
Neo’s platform serves as a control layer that governs AI agents, AI-enabled applications, and traditional software across enterprise environments.
Security operations teams can use the system to maintain a continuous catalog of active elements, such as agents, models, extensions, and MCP servers. Additionally, the solution evaluates these discovered assets to identify excessive access privileges and configuration vulnerabilities.
The product includes real-time attribution mechanisms that trace individual software actions directly back to the originating human user, automated agent, or specific application identity. It can natively enforce granular policies for tool calls, data movement, agentic workflows, and API access.
Security teams can restrict unauthorized activities or pause suspicious operations for manual review.
Neo was founded by Nick Warner, Shlomi Salem, and Eran Shirazi. Warner serves as the company’s CEO, having previously held leadership roles at SentinelOne (president and COO), Cylance, McAfee, and Forepoint.
Salem (CPO) previously led detection engineering at SentinelOne, while Shirazi (CTO) co-founded customer experience firm EasySend.
“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,” said Warner. “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.”
