The experience

From nearby to hello — without the swipe loop.

BonjourB helps people notice who is nearby, make a low-pressure first move, and decide together whether to continue the conversation.

01

Nearby Radar

See who is genuinely nearby, with clear controls over when you are visible and what other people can discover.

02

Say Hello

Make a small first move. If the feeling is mutual, exchange cartes de visite and open a private conversation.

03

Local games

Events and communities can add playful goals and rewards while the real point stays the same: meeting people around you.

Coming next

Bonjour,
Lausanne.

We are preparing a focused 2026/2027 pilot around Lausanne’s university community: enough people in the same places to make nearby discovery feel useful from day one.

Join the pilot

What we want to learn

  • Whether nearby discovery feels welcoming and safe
  • Where Radar is most useful on a normal day
  • What makes someone comfortable sending a Hello
  • Which introductions become real conversations
  • What brings people back to their Entourage
