- Ent
Participated · Seed · Jun 2026
Ent operates an intent-aware Workspace Security platform that observes behavior across browsers, applications, workflows, data movement, and local runtimes to evaluate human and AI agent intent in real time. The platform runs as a lightweight agent hosted in the customer’s cloud, applies customer-defined policy, and performs configurable, just-in-time interventions to stop risky actions before they become incidents. Ent is generally available for Windows, macOS, Linux, and via a browser extension and is deployed with Global 2000 customers across hospitality, financial services, and defense. The company was founded by Elias Manousos and Brandon Dixon, founders of RiskIQ and contributors to Microsoft Security Copilot, and includes advisors with senior security and intelligence backgrounds. Ent plans to use new funding to hire across engineering and go-to-market teams and to accelerate product roadmap items including AI governance, threat prevention, security integrations, and multimodal endpoint intelligence. The company positions its technology as a preventive layer at the workspace to address AI-era, fast-moving attacks by bringing AI reasoning directly to endpoints.

Armada builds and delivers modular AI infrastructure — including Galleon manufacturing systems, Leviathan megawatt-scale modular data centers, and Triton portable units — for high-density training, inference, sovereign neo-cloud and multi-tenant compute environments. The company has documented rapid commercial traction, reporting 540% customer bookings growth in FY25–26 and a 2000% bookings increase in Q1 FY27 year-over-year.

Armada is expanding manufacturing capacity with Galleon Forge One, a planned up-to-400,000-square-foot factory in Arizona expected to create about 500 jobs, enabled by a framework agreement and investment from Johnson Controls. The company has built an ecosystem and marketplace with partners including Microsoft, NVIDIA, Palantir and Dell Technologies to accelerate customer deployments and maintain control over sensitive data and models. Armada has raised capital totaling nearly half a billion dollars to date and is using that funding to scale production, meet accelerating global demand, and support new initiatives.
