Neo raises $100M led by a16z, Bessemer to secure AI agents

Legacy endpoint tools can't tell if an action came from an employee or the AI agent using their login.

• Neo emerged from stealth with $100M in combined funding: a $75M Series A led by Andreessen Horowitz and Bessemer Venture Partners, following a previously undisclosed $25M seed round from 2025.
• Founded by former SentinelOne, Wiz and Palo Alto Networks executives, Neo builds a real-time control layer that inventories and governs AI agents, AI-enabled apps, browsers and digital identities inside enterprises.
• The platform provides real-time attribution, tying every software action back to a specific human, agent, application or identity, and can natively block risky agentic activity without handoff to another tool.
• Neo currently employs 50 people, including 40 based in Israel, reflecting its dual Boston-Israel operating structure.
• Andreessen Horowitz argues that EDR, DLP and Zero Trust systems -- built for an era when only humans clicked and ran programs -- break down once agents inherit the same permissions and credentials.
• As AI agents get embedded into browsers, dev tools and SaaS platforms with valid user permissions, distinguishing agent action from human action becomes a foundational enterprise security problem rather than a niche feature.
