How did you get your first 10 sellers for a two sided marketplace? i will not promote

hey all, bit of a newbie question so bear with me i'm building a marketplace for digital products, things like ui kits, design systems, website templates and coded components. over the last month or so i've spoken to 50+ creators one on one, mostly over linkedin messages, and honestly the conversations have been really good. people are curious and a few have already said yes to listing once we're live but i'm stuck on the classic chicken and egg thing. creators want to know there are buyers before they put in effort, and buyers obviously won't come to an empty shelf what i'm doing right now is giving the very first few sellers a better deal than everyone after them, talking to every creator personally instead of mass messaging, and keeping it non exclusive so nobody has to leave wherever they sell today what i'm not sure about: is 10 good sellers enough to start, or do you need way more supply before opening to buyers? did you seed the buyer side yourself somehow, or let sellers bring their own audience at first? anything you did early that you'd never do again? would love to hear from anyone who's built a marketplace, even if it didn't work out. failure stories are probably more useful for me tbh
