Depop started as a simple app to post photos of clothes and offer them for sale. But it has become a cultural phenomenon with millions of users, a vibrant community and even some superusers making a living from the platform. That’s why I’m excited to announce that Depop CEO Maria Raga is joining us at TechCrunch Disrupt Berlin.

Many have tried to merge a social app with a shopping experience, but few have succeeded. Depop is one of them. If you’re an Instagram user, the app looks familiar with its outline icons. But instead of following brands and sometimes buying new items, Depop is all about vintage items, rare sneakers and things you simply can’t find on a regular social network.

Depop users can follow other users, discover items from their favorite brand, get personalized recommendations and, of course, buy and sell items. It’s a social experience that works particularly well on mobile and makes shopping more personal.

Selling something on Depop is as easy as posting photos on a social app. You enter a description, a location, a brand and a price and you’re good to go. After that, other users can buy stuff directly from the app. You can then ship your items and get your money on your PayPal account.

And it’s been a massive success. There are currently more than 13 million users — the vast majority of them are under the age of 26. The company has handled more than $500 million of gross merchandise value since its launch.

Interestingly, some superusers thrived on the platform. Those users are talented when it comes to spotting and acquiring limited-edition clothes, sneaker drops and other valuable items. They sell them on Depop, with some of them generating as much as $100,000 of revenue per year.

Under Maria Raga, Depop has raised more than $100 million. Earlier this summer, the company announced a $62 million funding round led by General Atlantic. It’s clear that Depop is now thriving as both a social app and a marketplace. And I can’t wait to hear how Maria Raga did it.

Buy your ticket to Disrupt Berlin to listen to this discussion — and many others. The conference will take place December 11-12.

In addition to panels and fireside chats, like this one, new startups will participate in the Startup Battlefield to compete for the highly coveted Battlefield Cup.
