OK, having looked through it, here is my feedback.
Custom Monzo.me urls used to be free for everyone if they contacted CS (as long as it was a variant of your name). This feels a tad tight to now include this behind a paywall, although if I can have monzo.me/batman, I may reconsider (other Superhero/Cartoon names also accepted…)
Monzo Plus cards are a nice touch, but again… They don’t add anything to my life (or anyone’s life), apart from those who really want to distinguish between personal and joint cards (it wasn’t dubbed the Monzo Fan package for nothing).
There are already free Monzo socials, and you can buy swag from the shop? If you started making swag available to Plus customers only, it would look petty… Making socials exclusive to plus customers comes across the same IMO.
So as of right now, I don’t see how someone could justify the cost, but I appreciate people will want a different coloured card, and that may be enough.
The insurance is an unknown add on, and until we know the cost, it’s impossible to judge.
The extra foreign ATM limit is just going to raise even more comparisons with other banks who offer an unlimited withdrawal limit for free (we are going to get the whole “Monzo charge for this, XXX bank don’t”.
Appreciate it’s extremely early days, and so much can/will change.
But that would be my initial feedback on what is available as of right now
