UGC ads for social meetups mobile app

Hi, We are launching a social meetups mobile app soon, and want to create around 10-15 videos a month to have around 10k~15k users in the next couple of months. We want organic videos that feel less like an ad and more like an excitement or awareness about the product. This number of videos is to try what works in content form, what doesn't. So its a plus if you are creative with ideas until one or two hit. This could be long term also.
