There are so many potential titles to support by going down this route.
Yep - having Mx is great. Do they also support Lord, Judge, MP, MBE, QC, or EUR ING (European Engineer - yep, this is a legal title!) and all the others?
What if your choice is not to be identified by a title at all?
No idea - But this is the follow up:
As far as I understand it, Monzo just automatically use Mx for everyone.
We have no internal concept of titles at all.
Iāve never really understood the need for titles! 
I think @GalaxyMergirl would be happy with this one, I have read some grumbles about it back in the days 
The searches from Monzo on my credit report show āMxā before my name. Where is that coming from - Monzo, credit agency or Noddle?
I have Mx on the searches but no title at all on the financial accounts bit for Monzo
Itās a good question, and Iām not too sure - @rika or @richardcadman may know the answer.
What I can confirm is that our internal customer tooling has zero concept of a title.
So, when I pull up a customers details, there are no titles anywhere in the tooling. Same if you requested all the details we hold on you, there wouldnāt be any reference to a title anywhere. From the looks Iāve had into some of the raw unprocessed data that we have before it gets formatted or parsed into our tooling interface, the concept wasnāt there either (although I havenāt spent a huge amount of time looking into our codebase since IANAP)
If itās something that the credit agency or Noddle require, then I would imagine it might come from them, unless itās a situation whereby weād be completely prevented from sending data to them with an incomplete required field, in which case it could be an ad-hoc append when that data gets sent out.
Starlingās response is that some systems require a title, and they considered internally using āMxā where needed, but they went this route.
I honestly feel the Monzo approach is better for those who this matters to. Thereās a huge amount of possible titles and the lack of flexibility offered just isnāt going to satisfy everyone.
I had both when Monzo searched me earlier this year - Mx and Mr.
I wonder if the Administration Review search was taken from my passport ID as it included my middle name and the Quotation Search didnāt.
Iām sure I read before that if something requires a title Monzo uses Mx. But I think it was on the diversity thread and Iām not going there to check 
But I like being Dr Rev Dave
Some really good discussion going on on the Starling forum on the Monzo vs Starling thread- features, diversity chat and all. Whoever he is, this guy is absolutely cracking me up.

I also did not know this was a feature. Pretty cool.

Youāll have to head over to their forum yourself to find out the result of that die roll. 
The wife part 
Same here
On my āadministration review searchā its mr with my middle initial
On my āquotation searchā itās mx with no middle initial
Aww, heās gone now. I was enjoying that.
That was bizarre 
I was literally LOLing. Though at the same time feeling bad for Starling. To lose a poll on your own forum like thatā¦ 
Hope not I prefer being a miss to a mx.
