startup is like that. if they got an idea that can be executed asap without too much risk they would go at it. low credibility is still a credibility it's better than being remembered as a crap companyGiven they are asking 50,000 Yen per person, and AR glasses cost around 30,000 Yen at the lowest end, My assumption is that they are just supplying the software and intend to buy the AR glasses for the event. If they mostly get returned afterwards, then it's a large one time investment.
Really, the more interesting unspoken thing is how the two people giving lessons (since the other two are sales) are supposed to scale to execute a 2,000 person conference. Maybe the goal is just to provide the glasses for existing Expo's, but then I don't understand how the Cram School gets them the credibility.
