How it works

Place a postbox at a location that matters to you.

Invite friends — only they can leave messages for you.

Visit the spot to collect the audio left in your postbox.

Privacy first

Only friends can send messages to your postbox, ensuring your personal audio space remains private.

Location-based

The physical collection of a message from a location makes it more valuable, more intentional and more meaningful.

Imbue place

Meaningful messages make places meaningful in and of themselves. Pick a place of existing importance or bring meaning to somewhere new.

Creating Personal Audio Connections

Our postbox feature brings more meaning to how we communicate through location-based audio messages. By allowing the creation of a personal collection point, connections between friends and family can become more meaningful, place-specific and enjoyed over time.
