US beta · Limited spots
Bumbei is opening in the US with a small group of early users. Leave your email and we’ll send you an invite to the app. Withdraw from 1 sat with zero fees: what you earn is what you get. Joining the beta is free. Separately, up to 20 selected Founding Members earn bonus sats for helping us test.
By joining you agree to our Terms and Privacy Policy. We'll only email you about Bumbei.
