hello beautiful humans
Nick here from Shopify. Really great questions!
I spoke to our theme partners team about them and they said the Shopify Theme Store is not like other theme marketplaces, as we do not accept individual theme submissions for listing. Instead, we look for Theme Partners to work with us on providing the themes for the store. As the Shopify Theme Store has an extremely high level in terms of requirements and criteria, it is vital to us that we find the correct Theme Partners to supply those themes. We aim to work with the chosen Theme Partners on a long-term basis to create the themes we feel are relevant for our merchants using Shopify.
