问HN：如何解决双边市场的冷启动问题？
我正在建立一个P2P众包运输市场，基本上就像BlaBlaCar，但用于包裹而不是乘客。旅行者在城市或国家之间移动时，会为需要寄送物品的人携带包裹。
我们即将推出最小可行产品（MVP），但面临经典的“鸡和蛋”问题。
旅行者在没有包裹可携带的情况下不会注册，而寄件人在没有可用旅行者的情况下也不会发布信息。每个市场创始人都说“先专注于一方”，但没有人具体说明他们是如何做到的，尤其是在你无法像使用SaaS着陆页那样伪造供应的情况下。
对于那些建立过P2P平台或双边市场的人：在你们的前50-100笔交易中，实际有效的方法是什么？你们是手动匹配人吗？对一方进行补贴吗？限制在一条路线或城市吗？

I'm building a P2P crowdshipping marketplace, basically BlaBlaCar but for packages instead of passengers. Travelers going between cities/countries carry items for people who need to send stuff.<p>About to launch the MVP and hitting the classic chicken-and-egg problem.<p>Travelers won't sign up without packages to carry, senders won't post without travelers available. Every marketplace founder says "focus on one side first" but nobody gets specific about how they actually did it, especially when you can't fake supply like you can with a SaaS landing page.<p>For those who've built P2P platforms or two-sided marketplaces: what actually worked for your first 50-100 transactions? Did you manually match people? Subsidize one side? Constrain to one route/city?
