AI That Knows Your Business

# ChatGPT doesn’t know your business. 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.

- ### You’re briefing it every morning

  ChatGPT doesn’t know your business. It never will. An AI with access to your docs doesn’t need re-briefing every morning.
- ### Your team’s using it behind your back

  People paste customer data and contracts into personal ChatGPT accounts. When your DPO asks, you have nothing to show.
- ### Your data lives on someone else’s server

  ChatGPT logs every conversation for up to 30 days. Fine for jokes. Not fine for contracts or payroll.
- ### You can’t leave

  Every conversation, setting, and user lives at OpenAI. With your own setup, all of that’s yours. Switch models anytime.

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.

| Criterion | 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, ChatGPT, Gemini—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.

ChatGPT prices are in euros.

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 ChatGPT 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 about 220 euros a 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), ChatGPT (OpenAI), Gemini (Google), Mistral, 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 are net; VAT is added only where it applies. We work with businesses, public bodies and nonprofits, not consumers:

- EU businesses, with or without a VAT ID, and organizations with a VAT ID: reverse charge (Article 196 of the EU VAT Directive). You account for the VAT; our invoice shows none.
- EU public bodies and nonprofits without a VAT ID, such as schools and associations: hosting and Website Maintenance carry your country’s VAT, which we report through the non-Union OSS (Ireland). Website builds, migrations, audits, the Fix Pack, the sprints and Managed Visibility carry no VAT (place of supply: United States, § 3a(1) UStG). AI agents: the one-time setup carries no VAT; the monthly hosting or maintenance fee carries your country’s VAT through the non-Union OSS, like Website Maintenance. You pay by invoice and bank transfer, not through Stripe.
- We check any VAT ID you give in VIES. If VIES doesn’t confirm it, we treat it as not given.
- Customers outside the EU pay no VAT.

## 30 minutes. Free. No strings.

We listen, and tell you straight up whether your own setup fits—or whether ChatGPT Teams is enough. Instant AI reply, human follow-up within 24 hours.
