Beautiful design btw.
Hey, I've spent a lot of time on social marketplaces from p2p and b2c over the past two years. I can share with you some insights as to the obstacles/marketing challenges you will face.
I've done everything from p2p white-label partnerships with institutions or fb ads to ppc to on-the-ground (spent 100,000+ on various efforts); built every functionality under the sun. at the end of the day, your business is going to be based on a true growth marketing strategy that will work with core features that resonate with users.
Let me know if you want to chat.
