New from Stack Consulting AI

A managed AI workstation. We run your business’s AI — you never touch the tools.

One machine, set up by us with the AI tools and automations your business needs, then maintained every month. Not another subscription you have to figure out alone.

A Mac Mini on a desk beside an Apple keyboard and display — the kind of machine a Stack AI OS ships on
The reality

You’ve got eight AI tools and a shoebox of logins.

Every week there’s a new AI tool you’re told you need. You sign up, poke at it, and it joins the pile. Nothing is connected, nothing is maintained, and none of it actually runs your business. An AI OS is the opposite: one machine, the right tools, wired together and kept running by us.

What is an AI Operating System?

Your business runs on people and software. An AI OS adds a third layer that does the work.

One machine we set up and maintain. Like a tireless employee who lives in a box on your desk and never quits.

1 — We set up the machine

A Mac, Windows, or Linux box, configured by us with the AI tools your business actually needs. It arrives working.

2 — Built for your business

We wire in the automations and integrations that kill your busywork — answering calls, drafting, research, the recurring tasks you do by hand today.

3 — We keep it running

We monitor it, update the models and tools, and maintain the automations. You never touch the tech. That's the whole point.

What’s inside

Real tools, named. No black box.

Agentic toolchain

Claude Code and Codex, installed and configured to your business — the same tools we build with.

Automation runtime

The automations we build run as code on a scheduler, watched, with an alert when something breaks.

Integrations

MCP connectors into Google Workspace, QuickBooks, and your CRM — so the AI works with the tools you already use.

Voice receptionist

Optional tie-in to our FreeSWITCH + OpenAI Realtime agent that answers and books calls.

Private models (Sovereign)

On Sovereign, models run on the box itself. Client data never leaves your building.

The Care plan

Monitoring, model and tool updates, automation maintenance, and support. This is the product.

Pricing

Pick a brain. Pick a body.

The tier is the brain — what the AI OS can do. The machine is the body — same brain, cheaper body if you want. The monthly Care plan is what keeps it all running.

Efficient, open source, best for Foundation

Windows mini$1,000

Best for MS Office / QuickBooks heavy stacks

Add-on: Office Rebuild

We rebuild and refresh the PCs already in your office into AI-ready machines that talk to your AI OS. $350 per seat, or bundle it into your Care plan.

Care covers setup, monitoring, maintenance, and support. Cloud model usage (OpenAI / Anthropic API tokens) is billed at cost on top — we don’t resell tokens or mark them up. On Sovereign, models run on your box, so there are no per-token cloud charges.

When local matters

For law, medical, and finance: nothing leaves the building.

Most businesses are best served by frontier cloud models — better answers, lower cost, nothing to maintain. But if you handle privileged or regulated records, the Sovereign tier runs the models on the machine itself. We already build for privacy-sensitive clients like Dr. Robert Woods’ psychiatry practice; Sovereign makes that the default.

Proof

We already run this for real businesses.
