Bump

One Bump identity

One Bump number for the plans your groups make everywhere.

Mention @bump to turn a busy group chat into a clear plan, useful recap, reminder, or next step. Your Bump number stays the identity people recognize across the places you choose to connect.

BumpHere’s the shape: Friday-night arrival, two nights, and a Sunday-evening return. Still to decide: flights, hotel, and one group dinner. I can compare options next.

One identity, clear connections

Your number is the anchor. Each place connects honestly.

Where a phone number is supported and verified, people can reach Bump through that number. Telegram uses a bot mapped to the same Bump identity. Slack uses a mapped app. They do not send through the phone number.

The number

Available only where verified

Your durable Bump identity. A number-addressed channel uses it literally only after that exact connection is verified.

Telegram

Mapped bot

A Telegram bot can represent the same Bump identity. Telegram messages do not travel through your Bump number.

Slack

Mapped app · Not available yet

A Slack app can map to the same Bump identity. It does not use your Bump number to send or receive messages.

WhatsApp Groups are unavailable. Saving interest does not provide access or a launch date.

Context you control

Bring the useful part—not your whole chat history.

You choose a saved preference or detail, the exact group that can use it, and when access ends. Revoke it anytime. Each group keeps its own memory, and Bump stays mention-only unless an admin explicitly changes that setting.
