Getting Exhibitors for First to Market Expo

I’m the co-founder of a new expo in NYC, first to market in the cute industry. All things from fashion, beauty, tech , media, film etc. Been coming up against a lot of ppl who say no to exhibiting because we’re first to market. Are there any suggestions on how to get past this when it comes to finding clients for your expo? Any suggestion would be appreciated.
