You could argue this is because its a fresh new, dynamic company, and you get the chance to get in on the ground floor. But your paying £5k for the privilege.
(Note: the SIC-code (identifying the nature of their business), "none supplied". They seem unsure as to what precise function they offer. Maybe they could decide they are "trainers" and thus circumvent all their bonuses etc, by saying "we only charge for training, and any losses are your own".
Equally, their offices:

Note: "Zero upfront capital". They essentially have no assets of their own. Try a "quick quote" and ask how quickly you could disengage their services. have the company signed up for a year?? if not, what would happen if they decided to vacate the offices 6 months into the OPs year-long training?
Have a great week guys.
