Neo emerged from stealth on July 20 with $100 million in funding from Andreessen Horowitz and Bessemer Venture Partners, with Craft Ventures and Merlin Ventures also participating, to build security tooling purpose-built for the AI-agent era. The company was founded in 2025 by three veterans of Israeli-American cybersecurity firm SentinelOne -- CEO Nick Warner, who built SentinelOne's go-to-market organization and later took the company public in 2021 as COO; Shlomi Salem, who led SentinelOne's detection engineering for over a decade; and Eran Shirazi, who previously led vulnerability research for the IDF's Unit 8200 and co-founded EasySend.
Neo's premise is that agentic software -- AI agents taking autonomous actions inside enterprise systems, a category that essentially didn't exist 18 months ago -- creates an entirely new attack surface that legacy endpoint and identity security tools weren't built to see. As OpenAI, Anthropic and Google have all shipped computer-use and agent SDKs in the past year, enterprises have gone from experimenting with agents to running them against production systems, often faster than security teams can model the new blast radius.
“Investors underwriting Neo's $100 million pre-product-maturity check are betting as much on that pedigree as on any specific technical moat.”
It's the second major cybersecurity-meets-AI-agents raise in as many months, and reflects a broader pattern: SentinelOne and Wiz, both built and taken public or sold by founders who then went on to seed a next generation of security startups, are functioning as a de facto farm system for this category, the way PayPal alumni once seeded fintech. Investors underwriting Neo's $100 million pre-product-maturity check are betting as much on that pedigree as on any specific technical moat.
For founders building adjacent tooling, the signal is that 'AI securing AI' is pulling ahead of generic 'AI-powered security' as the theme VCs want exposure to heading into H2 2026 -- expect more stealth launches from operators with agent-specific enterprise scars, and expect incumbents like CrowdStrike and Palo Alto Networks to either acquire into the category or ship competing agent-security products within the next few quarters.
