Isn’t that the point though? They couldn’t cover the costs of something they promised, because they weren’t/aren’t making enough money.
People criticise Starling for not pumping out features like Monzo is doing, but Starling should have a business model which is sustainable, and guarantees the customer doesn’t suffer.
I’m impressed by the rate of new features coming out of Monzo in the past few months - But facts are facts - Customers were lured in with a promise (free international withdrawals), and then when people were on board, they changed the rules.
