OpenTalk: The secure and sovereign Open Source Alternative to Zoom.

Most businesses default to Zoom or MS Teams without thinking. But if you actually care about where your confidential discussions live and who has the keys to watch them, that default choice is a liability.

Whether you are a freelancer, a startup, an SME, a large enterprise or a government agency this isn't just a technical risk; it is a ticking compliance and data privacy time bomb.

Enter OpenTalk.

The Berlin-based counter-weight to the US video oligopoly. It is not a feature-bloated clone, it is a platform designed to strictly follow EU law, rather than just finding workarounds for it.

💼 Strategic Value: Why should you care?

⚠️ The Friction Point: There is currently no native mobile app (iOS/Android are on the roadmap). It runs via mobile browsers (PWA).

🎯 Verdict:

A "Strong Buy" especially for Government, Defense, and Legal sectors requiring an air-gapped or strictly European stack. A "Wait" for mobile-first teams.

Autonomy on paper.

Switzerland's CHF 7 billion government cloud tender, read against the goals Parliament set in 2024. The goals written as conditions survived; the ones left as wishes faded. And the right to take over the private cloud is only worth the team inside government that could use it.
