But your own agent does.

The Problem

Why “just use ChatGPT” doesn’t cut it anymore.

Four reasons a consumer subscription is the wrong tool for a serious business.

Four Paths, Compared

Four real ways to run AI inside a business.

From zero setup to maximum data sovereignty. These are the four options that actually come up in conversations with mid-market clients—compared honestly.

Consumer ChatGPT Plus Vendor Cloud ChatGPT Teams What We Recommend Your Server + API LLM Maximum Sovereignty Your Server + Ollama
Where your data lives US (OpenAI) US (OpenAI) Your server in Germany Your server in Germany
Used for model training? Opt-out required No (contract) No (DPA with LLM vendor) No—everything stays local
GDPR posture Borderline on sensitive data Workable with Enterprise DPA Clear with standard DPA Maximum—nothing leaves your network
Conversation audit trail Barely visible Limited (admin panel) Full, on your side Full, on your side
Swap models? Locked to GPT Locked to GPT Claude, GPT-4, Mistral—one click Llama, Mistral, Mixtral—one config
Typical cost (10 users) €240/month €220/month €150–400/month €200–500/month + GPU server
Setup effort None Account admin, ~1 day We handle it, ~1 week We handle it, ~2 weeks
Fits teams that are Solo users, experimental team Standard teams, non-sensitive data Mid-market, GDPR-conscious Legal, pharma, government

The consumer Plus tier is rarely the right answer for businesses—it's in the table for orientation because many teams start there. The jump to Teams or a self-hosted setup usually happens around 5–10 regular users.

From the Founder

Why I use this myself.

I’m Alexander. I run Digital Domination and Jetzt Übersetzt.

Eighteen months ago I started using Claude every day across both companies. Three problems, fast: re-briefing the AI every morning, pasting sensitive stuff onto US servers, and zero control over when someone might pull the plug.

So I built my own—a server in Germany, Claude and GPT-4 over API. For context: my notes, my calendar, my key contacts, my Trello board, my to-dos. Plus selected data from my fitness tracker.

Now my “Klaus” (that’s what I named my agent) has the full picture—and actually takes work off my plate instead of getting re-briefed every morning.

What I built for me, I now build for other founders. Dealing with similar issues? Let’s talk.

FAQ

What clients ask most.

How much does a self-hosted AI solution cost per month?

Setup for 10 users typically runs €150–400/month (server + maintenance + model usage). Often cheaper than ChatGPT Teams at ~€220/month—and your data stays in Germany instead of on OpenAI's US servers.

Is a self-hosted AI worth it, or is ChatGPT Teams good enough?

ChatGPT Teams is legit. But: everything lives at OpenAI, models are locked, and leaving is painful. Your own setup keeps every conversation yours, lets you swap models, and stays portable.

Is a self-hosted AI setup GDPR-compliant?

Yes, when set up right. Servers in Germany, Article 28 GDPR data processing agreement, your content isn't used for model training. We deliver every document your DPO needs. The legal call is theirs—we supply the material.

Which AI models can I run on a self-hosted setup?

Claude (Anthropic), GPT-4/5 (OpenAI), Mistral, Gemini, Llama. All behind one unified API—swap models with one click, every conversation and every doc stays put.

Where is my data stored with a self-hosted AI solution?

On your own server in Germany (Hetzner Falkenstein). Not on OpenAI's US servers. At project end you get full server access, backups, docs, and a written handover—complete data export on request.

Does a self-hosted AI scale from 10 to 100 users?

Yes. The 10-user setup grows with you transparently. Past 50 users we add a second server—you won't notice beyond "it keeps working."

Are prices shown gross or net? How is EU VAT handled?

All prices shown are net B2B excluding taxes. Invoices are issued as follows:

  • EU customers with a valid VAT ID number are invoiced via the reverse charge method under EU VAT rules (e.g. Article 196 of Council Directive 2006/112/EC)—no VAT is added to the invoice.
  • EU customers without a VAT ID (private individuals, schools, public bodies, small businesses) are invoiced with VAT at their country’s standard rate, which Digital Domination declares quarterly via the EU One-Stop Shop in Ireland.
  • Customers outside the EU receive invoices without any tax applied at all.
