About
CambridgeNexus (CNEX) is a Boston-based AI Factory operator that owns bare-metal NVIDIA GB300 NVL72 racks and leases them whole, single tenant, from an allocation of 350+ racks across Tier III facilities in six US states and Taiwan, installed within 75 to 90 days of contract.
Not a GPU marketplace and not a virtualized cloud. Customers lease full racks: bare metal, single tenant, no instances, no shared hardware. Seven operating layers run under one model: power, cooling, networking, compute, orchestration, compliance and customer workload planning.
What a customer gets:
- Full-rack NVIDIA GB300 NVL72 and NVIDIA Vera Rubin systems, from one rack upward
- Lease terms from 6 months to 5+ years
- Tier III facilities in USA and Taiwan
- Contract to installation and acceptance in 75 to 90 days
- 99.95% uptime SLA
- SOC 2 Type I, GDPR and HIPAA; ISO 27001 and FedRAMP 20x in progress

About
MacDuty rents dedicated Mac mini servers from its own racks in Romania, inside the EU. Every machine is bare metal and assigned to one customer: no virtual machines, no shared hardware.
The fleet covers every Apple silicon generation from the M1 to the 2026 M6 and M5 Pro, in 84 configurations. Machines arrive with a clean macOS install, reachable over SSH and screen sharing in minutes, with a public IPv4 and IPv6.
Billing is by the day, the month or the year, with no setup fee and no minimum term beyond the 24 hours Apple imposes on everyone. Paying yearly takes 20% off. Power is unmetered, 10 TB of traffic included.
From the client area you restart the machine, reset its password, manage SSH keys and reinstall macOS yourself. Nothing is locked down: your own Apple account, your own backups. Failed hardware is replaced the same day.
Typical uses: CI runners for Xcode and GitHub Actions, always-on dev machines reached from Windows or Linux, local language models, AI agents.
