When I wrote its game on afterMondobecame the last of the four British challenger banks to secure a banking license earlier this month, I didnt think competitor Starling Bank would take my words quite so literally. But thats just happened in the form of a domain name prank following Mondos announcement that it has changed its name to Monzo aftera trademark dispute forced the young company to rebrand.

As Monzo co-founder and co-CEO Tom Blomfield (who previously founded GoCardless) was unveiling the new name yesterday evening at an event held at the startups London office and live streamed on YouTube, little would he haveknown that somebody at rival Starling Bank had registered the domain name getmonzo.co.uk a domain unfortunately similar to the startups existing getmondo.co.uk.

A visit to the getmonzo.co.uk address reveals a message from Starling Bank founder and CEO Anne Boden congratulating Monzo on its rebrand and promoting the startups own wares, including the slogan: Anything is possible.

What most visitors wont be aware of is that the latter is a bit of an in-joke between Monzos Blomfield and Starlings Boden, since Starling Bank itself changedits name from BankPossible and the two challenger bank founders have history.

Blomfield previously teamed up with Boden to help start Starling before tensions led him to venture out on his own, taking three of Starlings team with him, according to a report in the FT. One of those is also Monzo co-founder and CCO/Head of Product Jason Bates.

When we heard the rumour [of thenew name], we checked whether the trade mark was registered and found that it was at preregistration, explains Boden. We then checked the domain and found that a few Monzo Bank domains had not been registered. We were quite surprised. It was too good to be true and we couldnt resist having some fun.

And fun the Starling team had, with lots of self-congratulatory re-tweets appearing as fintech industry watchers and Monzo users, who were actually asked to crowdsource the new name, began to notice the prank.Fans of Monzo and Starling joined in. Its a great community doing something exciting, adds Boden.

As for what will happen to the getmonzo.co.uk domain next, Im told Starling Bank plans to auction it off for charity and match the resulting donation.Stay classy.
