Le Carillon (network of solidarity shopkeepers)
Network of neighbourhood shopkeepers (boulangerie, café, hairdresser etc.) who pledge specific small services to homeless people - a glass of water, toilet access, a phone charge, a free haircut. Identified by visible Carillon sticker on the window; mapped per arrondissement.
Tracked and listed by arrondissement / city - each arrondissement (and now city) has its own count of pledged carilloneurs, creating implicit area-vs-area participation rankings and a roll-out leaderboard as new districts join.
Within an arrondissement, shopkeepers, residents and local associations coordinate to recruit new businesses, run district 'maraudes' (street outreach), and run conviviality events with homeless neighbours. Strong neighbourhood-scale collective identity.
A non-app, network-based example of explicit *area-by-area roll-out* with strong intra-area solidarity. Demonstrates that BelongHub's catalog should include *offline* hyperlocal networks, not just apps. Excellent illustration of pledge-based participation aggregated to a district unit.
