BChat enables offline communication using Bluetooth mesh networking when internet access fails.
About the startup
What are you building?
BChat is an offline-first communication platform that allows users to send and receive messages without internet connectivity. Using Bluetooth mesh networking and a decentralized gossip protocol, messages are relayed across nearby devices, extending communication beyond direct Bluetooth range. BChat is designed for rural communities, emergencies, campuses, events, and other environments where internet connectivity is unavailable, unreliable, or congested.
Problem you're solving
Most communication platforms depend entirely on internet connectivity. When networks fail due to outages, poor infrastructure, emergencies, or congestion, communication stops completely. BChat provides a resilient offline alternative that keeps people connected even when the internet is unavailable.
