Yesterday at eTail West 2014, I got the chance to sit down with Manish Chandra, CEO and Founder of Poshmark.

Poshmark began as a mobile-only fashion marketplace where customers can buy and sell items from their own closet. They are an end-to-end solution provider for women (or men), so once you make a sale of an item in your closet to another Poshmark member, they send you a pre-paid shipping label, making selling your items a seamless experience.

Though the main goal was to set up a commodity marketplace, Poshmark has also been able to create a sense of community between its members with the creation of Posh Parties, buying and selling parties that can take place either online or in person!

Though 85% of transactions on Poshmark happen via the mobile app, Poshmark has extended its platforms from only a mobile app, to a tablet app and responsive sites for mobile, tablet and desktop in order to make it easier for any customer using any platform to share their clothing items.

Poshmark is also extremely active on social media with a presence on Facebook, Twitter, Tumblr and Pinterest. In fact, due to Poshmark’s innovation on Pinterest, they were featured on Pinterest’s homepage as a ‘how-to’ case study for other retailers.

Manish’s company and their mobile innovation garnered them the attention of their retail peers, which led to their nomination as finalists in the eTail Best-in-Class Awards in the mobile/tablet category. As such a innovative mobile expert, what does Manish think the most important to keep in mind is when creating a mobile site or app? Making sure you think through every possible error! There is no point in creating a beautiful mobile app or site if your customer is going to encounter problems every time they try to use it. A combination of simplicity, elegance and innovation are the keys to successful mobile integration.
