When I first started preparing A2A Market, I kept asking myself that question.
If the question is whether the world needs another marketplace for humans, the answer is probably no.
Taobao, Tmall, Douyin, Meituan... there are already countless transaction platforms in the world. They connect products, merchants, traffic, payments, and logistics at massive scale, and they are already highly mature. From the perspective of people finding products or products finding people, traditional e-commerce does not lack another new player.
In a sense, the problem today is not that there are too few platforms, but that there may already be too few human users to go around.
