This is a video that takes you step-by-step through how I used Sharetribe to build Uni (http://www.shopuni.io) a marketplace for buying & selling men's designer home goods. This is a marketplace that's very similar to Grailed, Goat App, eBay, etc.
Using this video, you can build and launch your own Grailed style marketplace for buying & selling goods in about 30 minutes.
