Anybody know anything about letsescape.co.uk? Just bin asked to go to a business mtg don't know wot its about

I want to set up a business of some sort but don't really know what. I've been offered a chance to go to a business meeting for this company but neither the people who asked me nor the web site tell me much about it. Has anybody been involved with it? and it genuine? Is this some sort of pyramid? Do you only make money at the top?
