Everything Marketplaces was recently started in 2020 by Mike Williams (Yoroomie) and has quickly grown to become what has also been referred to as the "go-to" & most helpful community for marketplaces founders & teams.
Everything Marketplaces is also a community with hundreds of marketplace contributors, which includes those who are bootstrapping marketplaces, pre-Series A, to even founders & leaders from some of the largest online marketplaces like Airbnb, Uber, Turo, eBay, RigUp, Thumbtack, Yelp Grailed, Hipcamp, and others. The group also includes marketplace domain experts contributing & sharing insights, such as former (and some current) partners at a16z, Greylock, and Benchmark.
