I made the mvp, not public yet because i am adding the Business partners to the platform first to propose enough items to the final customers, the Business partners onboarding part includes few interactions that i should have with them plus the content creation part (them sending me pictures of their products or me helping them create content about it), I am just wondering if anyone who did already this kind work publicly documented the process so i can learn and apply it faster else i am already working on it. And yes, totally agree with you on attracting the buyers and focusing on them, i am dedicating a part of my time for that too to be ready for after.
