Figaro Bros, the company, was formed in February 2018.
The Figaro Brothers, the characters of The Big Top, were introduced in the 2015 incarnation, which was also notoriously well known for including many Derren Brown Easter Eggs. The brothers were the Ringleader, Kenny the Clown and Big Baby. The Ringleader and Big Baby were characters within the maze. Kenny the Clown was a nod to Paul McKenna, a hypnotist who Derren once was friends with, but had a falling out with. The name Figaro came from the name of one of Derren's pet parrots, as did the name for Madame Mephisto. I believe the Ringleader, who had a bit of an Eastern European accent in adverts and announcements, was to be called Rasputin, after Derren's third parrots, but that was never formally announced... Anyway, I digress...
What it likely is is that this newly formed company is made up of a former employee(s) of Thorpe who has decided to work on their own projects now. They're probably using their work at Thorpe as an example to help get their exposure up. It happens regularly enough - people get experience at a large company, then use that experience and the contacts they make to start up their own company, or join a startup company, with a greater say in things.
