After limited beta testing, the Berlin based digital challenger bank is now launching in the US with open registration. It has also announced Shares Spaces which lets users share sub-accounts with other users in just a few taps (essentially an N26 joint account).
Sending an invite is the equivalent of granting a power of attorney on a Space. The admin of the Shared Space is the only person who can add and remove participants to the Shared Space. So it’s not technically a joint account, as joint accounts have multiple owners.
