Over the last decade, we’ve seen the marketplace model evolve and grow, and this year a16z is back with our fourth edition of the Marketplace100 – a ranking of the top private marketplaces by GMV – giving a unique window into what may be to come.

This year’s list features nearly three dozen newcomers, including marketplaces for refurbished electronics, precious metals, and sustainably raised meat. And in this episode, we break down key trends from the report together with a16z’s Consumer partners Connie Chan, Olivia Moore, and Zach Cohen.
