Zenity's $125M Series C: Norwest Bets on Security for Autonomous AI Agents
Norwest led Zenity's $125M Series C with SoftBank Vision Fund 2, Hitachi, and LG — enterprises need intent-aware controls as agents act on critical systems.
Model-layer security is yesterday's problem. Agents that act — open tickets, move money, rewrite code, touch SharePoint — are today's. Zenity raised $125 million Series C led by Norwest Venture Partners on August 3, 2026, to own that layer.

Who uses the product — and why they pay
Zenity sells AI agent security and governance to large enterprises that already deployed copilots and custom agents into production. Customers span regulated industries; SoftBank Corp's CISO publicly cites Zenity for visibility and control as agent use grows.
Coverage claim that matters for buyers: one control plane across Microsoft Copilot, ChatGPT Enterprise, Gemini, Claude/Codex/Cursor coding agents, and custom stacks on Bedrock/AgentCore, Microsoft Foundry, Vertex AI.
Mechanism (editorial summary of company claims): understand intent, then deterministically allow / modify / block before the action lands — not only prompt filters after the fact.
Why now
Enterprises finished the pilot theater. Agents now touch SaaS, local coding tools, browsers, and cloud infra. Prompt inspection alone cannot govern tool use. Zenity Labs research (AgentFlayer, Copilot Studio issues, document-poisoning paths) made the threat model concrete for boards that already approve agent rollouts.
Company-stated growth signal: revenue tripled each of the past two years, with another triple in sight for 2026 — treat as management-reported, not audited.
Why Norwest — and why SoftBank/Hitachi/LG sat in
Norwest leads growth-capable enterprise rounds ($10M–$30M venture checks scaling into larger growth equity). Partner Assaf Harel framed Zenity as early-mover with Fortune 1000 implementations — classic Norwest "category leader at scale" underwriting.
Strategic participants map to distribution, not vanity:
- SoftBank Vision Fund 2 + SoftBank Corp as customer → reference + Asia expansion.
- Hitachi Ventures / LG Technology Ventures → industrial and enterprise channels where agents meet OT/IT risk.
Likely founder reasons to take this syndicate:
- Growth lead that has done enterprise security software before.
- Corporate-strategic capital that doubles as design partners in APAC.
- Category crowning while Gartner already named Zenity "the company to beat" in AI agent governance (April 2026 report — vendor race commentary, not a ranking we invent).
Competitive map
| Approach | Limitation |
|---|---|
| Model safety / red-teaming | Stops at the model, not tool actions |
| DLP / classic CASB | Weak on agent intent and multi-tool chains |
| Zenity-class agent governance | Purpose-built for autonomous actions |
When not to extrapolate
- Agent platforms bake equivalent controls into the OS of Copilot/ChatGPT and compress the independent market.
- Revenue triples prove uneven across a few whale logos.
- Israel–US GTM complexity slows the Europe/APAC push the round funds.
Practical takeaway
CISOs: Budget for agent runtime policy the way you budgeted cloud CSPM five years ago. Investors: The wedge is pre-action enforcement across heterogeneous agent frameworks — not another prompt firewall.
