The venue Wi-Fi doesn't matter.
Convention halls, lecture blocks, dorms, and stadiums: dense crowds, concrete, and captive-portal Wi-Fi that never works. FLVSH runs on the one radio that doesn't need a password.
Every conference has the same connectivity theater: a Wi-Fi password on a lanyard, a network that collapses by the first keynote, and a group of colleagues trying to find each other across three halls on messaging apps that need what the venue can't provide.
FLVSH sidesteps the whole stack. Attendees discover each other by proximity — no exchange of numbers, no QR codes, no account linking. The hall's worth of phones relays messages across the building, and what you say stays between your keypairs.
Discover people in the room
FLVSH shows you who's nearby and running the app. Tap to exchange keys and chat — no phone numbers traded, no contact permissions granted.
Concrete-proof coordination
Basements, parking structures, and elevator lobbies are BLE territory. The mesh threads through spaces cell signal can't.
Nothing lands on the venue network
No captive portal, no shared Wi-Fi, no traffic for the venue to inspect. Your messages never touch their infrastructure.
Proximity is the address book.
