Brief

a16z announced it led Neo's Seed round on 2026-07-20, arguing that AI agents now run directly on endpoints with user-equivalent privileges and thus invalidate assumptions behind EDR, DLP, and Zero Trust. Neo aims to provide agentic software controls; its founders—Nick Warner, Shlomi Salem, and Eran Shirazi—bring extensive SentinelOne and startup experience, and WSJ reports a $100M raise.

Why it matters

a16z announced it led Neo's Seed round (post dated 2026-07-20), backing Neo to build 'agentic software control' for AI agents running on endpoints with the same privileges as the users they serve.

Key details

  • The authors claim legacy controls—EDR, DLP, and Zero Trust—'break' once systems cannot distinguish actions taken by a human versus an AI agent, since agents can act continuously and often outnumber humans.
  • Neo's founding team: Nick Warner (scaled SentinelOne through its IPO), Shlomi Salem (ran threat research at SentinelOne for 11+ years), and Eran Shirazi (co‑founder and former engineering lead at EasySend); WSJ reports Neo raised $100 million from stealth investors.
Source evidence

We're excited to lead Neo's Seed round.

AI agents now run directly on the endpoint with the same privileges as the user they serve.

Every control built on the old assumption (EDR, DLP, Zero Trust) breaks the moment it can no longer tell whether an action came from the person at the keyboard or the agent acting in their name.

@neoaisecurity is pioneering agentic software control for a world where AI agents act continuously, often outnumbering the humans they serve.

Neo's founders are as strong as they come in security. Nick Warner scaled SentinelOne through its IPO. Shlomi Salem ran threat research there for 11+ years. Eran Shirazi previously co-founded and ran engineering at EasySend.

Congrats, Nick, Shlomi, Eran, and the Neo team.
