A few years ago I have gotten a joint account with my wife over at GLS. Not as Internet savvy company but finally Apple Pay for their credit cards. They are investing in a lot of green tech, small businesses. Probably they have invest in some esoteric shenanigans but as a customer of that bank you can actually choose where your Money gets invested.
"Hip" is really the last thing I want in a bank, the N26 advertising totally misses the mark for me. Their technology seems to be kind of crap, too. Security holes due to gross incompetence. https://media.ccc.de/v/33c3-7969-shut_up_and_take_my_money
DKB rejects applications unless you have German PR or citizenship and it is mainly in German.
Here is a DKB subsidiary https://www.dkbcodefactory.com/ advertising as a start-up.
That seems like a highly dubious way to evaluate a bank.
Personally I use Monzo for personal banking, and Starling for business. Though starling has a personal banking product too.
