I see you guys still have only one video on your youtube channel. Please fill that space with more videos, that will definitely get you more potential users in the long run.
There are people that will only go on YT and get their info on that, so it's never smart to ignore those potential users. It doe's not have to be a big production, lower quality videos are cheap and not a big problem to produce.
Someone with a lot of followers can do wonders for promo. so the team shouldn't ignore that.
