Collaboration Platforms
Collaboration platforms combine document editing, messaging, video calls, and project management into integrated productivity environments. They are the operational backbone of distributed teams. European alternatives to Google Workspace and Microsoft 365 exist but face an adoption gap — the key differentiators are offline capability, third-party integrations, and the depth of real-time co-editing features.
