Launching a marketplace tips and strategy 💡

Hey everyone, I've been part of the Product Hunt community since its inception in 2014, and I've launched over 25 products, all of which reached the top 5. However, this time, I need your insights! We're embarking on a new journey with digital design products, moving to marketplaces. Instead of selling finished products this time we created a marketplace and we’re inviting designers to sell their design assets and connecting them with end users who want to purchase these assets. What strategies would you recommend for this approach? Your advice and ideas would be greatly appreciated! Check out the project here: https://www.producthunt.com/products/vectopus
