Marketplace 100
Earlier this month Andreessen Horowitz released Marketplace 100.
“Marketplace 100, a ranking of the largest and fastest-growing consumer-facing marketplace startups and private companies.”
Food, travel & groceries dominate the list.

And celebrity shout out services are a thing, and at number 67.
“By offering celebrities an easy way to make money and build rapport with their fans, Cameo (#67) unlocked a tidal wave of demand among consumers yearning to purchase celebrity shout-outs for friends, family, even themselves.”
“The Marketplace 100 reveals a number of themes—the strength of network effects, differentiated supply, consumer behavioral tailwinds, defensible distribution channels, and more—that fuel a business’s long-term viability and allow certain marketplaces to flourish.”
