Dive Insight:

Poshmark isn’t the only fashion re-selling platform getting attention and funding these days — the RealReal garnered $40 million in a recent funding round as well. But Poshmark’s approach of keeping sellers and buyers in direct contact, eBay-style, and its democratic all-comers policy, which doesn’t limit it to luxury items, may both be key to its ability to scale.

Both have led to flexibility that is allowing sellers to develop consignment-boutique-like presence, says CEO-founder Manish Chandra. Chandra also says the company’s mobile-first profile enables a social aspect that also fosters growth and that enables the algorithms that helps match buyers and sellers who are meant for each other. The Apple Watch will only continue all this, Chandra says.

“Anything that increases the efficiency of communication and information…has the opportunity to be a killer platform,” he told TechCrunch.
