Rumgr is a mobile app that brings the garage sale experience to the palm of your hand. Take a picture, and your item is for sale to everyone around you. Founded in fall of 2011 by the top mobile and web development talent at Zappos.com, and backed by Tony Hsieh among other angel investors, the company has quickly grown a vibrant community of 5,000 loyal buyers and sellers.
No descriptions, no tags, and no location details are needed. Rumgr uses the features endemic to mobile (camera, GPS, messaging, push notifications) to make posting an item for sale quick and easy.
The buying experience is just as seamless and can even be fun. Just as you would browse a garage sale, users "rummage" in the app in their spare time, while waiting on line or hanging out at home. Items appear in the image feed in order of proximity, so the top items could be as close as 200 feet away.
New features launched in summer 2012 allow for Facebook integration, tools for faster communication, more control over items for sale, and transaction history. Rumgr has also just introduced Groups, which are smaller, more intimate marketplaces based around a common location, such as a workplace or university.
