OfferUp

OfferUp was created in 2011 by Nick Huzar, former co-founder and CTO of Konnects, Inc., and Arean van Veelen. OfferUp is a mobile-driven local marketplace that competes with companies such as eBay, Craigslist, and Facebook Marketplace.

In 2015, OfferUp was named one of the Hottest Startups by Forbes, citing the company's explosive growth between funding rounds throughout the year, and was speculated to take over Craigslist's share of the C2C marketplace. Since then, the company has become a large marketplace for buyers and sellers and was named one of "The 7 Most Innovative Startups in Seattle" by Inc. OfferUp was in the Top 50 most downloaded free apps on Apple Appstore and Google Play and has been praised for being more user-friendly to list products on than sites like eBay.

OfferUp is based out of Bellevue, Washington and is currently used in several major cities across the United States, with plans to expand internationally. The company moved into a new office space in 2017 which was furnished only with items found on the platform.

The OfferUp platform, offered for iOS, Android, and the web, facilitates buying and selling of used goods. The marketplace, which is primarily optimized for smartphones, features large photos of products for sale via an infinite scroll interface. For buyers, products are featured based on the geo-location closest to the buyer to help encourage face-to-face user interactions, but can also be filtered by category, price, and distance. On the seller side, products are listed immediately by uploading a photo from a user's smartphone or computer; the platform makes it easy to sort inbound inquiries by the highest bid before contacting prospective buyers to agree upon a price and meeting place.

OfferUp currently offers a "bump" feature, which allows users to move their item to the top of the queue for increased visibility at a fee. Transactions are completed using cash or through OfferUp's in-app payment platform.

OfferUp conducted surveys about marketplace opportunities and saw that women, in particular, were hesitant because of safety concerns. Profile features for customization include verification badges, positive review attributes, average response time, trusted connections, and personalized background images.

The app includes messaging features for buyers and sellers to connect directly, without giving up personal information like an email address or phone number.
