Microsoft Copilot Alternative for Medium-Sized Businesses
Microsoft Copilot is powerful, but not the right choice for everyone. What Copilot actually costs, where the sovereignty gap lies, and what really matters when looking for an alternative.
Microsoft Copilot brings AI directly into Office — practical, but not without drawbacks: high license costs, dependency on the Microsoft ecosystem, and open questions regarding sovereignty. And the need for alternatives is real: According to Bitkom (September 2025), 93% of companies would prefer German or European AI providers; 48% cite data protection requirements as a brake on AI adoption.
What Copilot actually costs
The often-cited price of 30 USD per user per month is only the add-on. Copilot requires a qualifying Microsoft 365 license (E3/E5) — all-in, Copilot Enterprise ends up at around 66–90 USD per user per month. For medium-sized businesses, the Business add-on is currently available from 18 USD (promotional price), plus the base license. Anyone calculating should look at the total cost of ownership (TCO), not the list price of the add-on.
The Sovereignty Gap
Microsoft emphasizes that Copilot does not train foundation models with customer data and complies with the EU Data Boundary. However, two limitations remain: Certain models (Anthropic) are explicitly "out of scope for the EU Data Boundary" according to Microsoft, and requests from customers outside the EU may be processed in the USA. Above all, US jurisdiction remains. Before the French Senate, Microsoft could not guarantee, that data would never reach US authorities:
"No, I cannot guarantee that…"
Analyst Mike Small from KuppingerCole puts it bluntly: localization reduces risk but does not eliminate the legal basis for US access. Data Residency is not Data Sovereignty — more on this in our post on the US CLOUD Act.
What matters for an alternative
A good Copilot alternative does not score with a single feature, but with the overall package:
Multi-model instead of lock-in
Copilot only unfolds its value through deep Microsoft Graph integration — the deeper the tie, the higher the switching costs. The counter-trend according to McKinsey (State of AI 2025): companies are consolidating on platforms with access to multiple models — the right one for each task, with central governance and without vendor dependency.
Kasimir bundles several AI models under one interface, operated in a German data center — GDPR-compliant, without lock-in, with predictable costs.
Conclusion
Copilot is a good choice for corporations deeply embedded in Microsoft. Medium-sized companies are often better off with an open, sovereign platform. Our [guide/article/etc.] shows you how to select and implement such a platform.Guide to the AI Platform for Medium-Sized Businesses.
