There haven’t been any recent updates, but I was heartened to read this in the recent article shared by @Dunsford:
Monzo has even hit the one milestone that previously seemed impossible in financial services; women now make up 40% of the bank’s leadership.
It’s more important to be doing meaningful work internally to improve diversity and inclusion than to be publicity seeking on the topic without doing the work. I hope this is an indication that that is what’s going on at Monzo. Of course, once they get their house in order, they should also publicise it as a way to show others that it can and should be done.
