BirdyChat has become the first European chat app to achieve interoperability with WhatsApp under the Digital Markets Act. This allows users to exchange messages across platforms without forcing contacts to switch apps, removing a major adoption barrier for work-focused communication. The rollout is currently underway across the European Economic Area.

The integration uses WhatsApp's official Third-Party Chats interface, ensuring all communication is end-to-end encrypted. Users can start 1:1 chats using a contact's phone number, send files, and maintain work conversations within BirdyChat while their contacts stay on WhatsApp. This addresses a long-standing fragmentation issue in professional messaging.

Availability is gradual, requiring both parties to be in the EEA. Currently, only 1:1 chats are supported, with group chat interoperability planned for a future update. BirdyChat remains invite-only as it scales access, offering a potential solution for separating work and personal communications without sacrificing reach.
