## About

Based in Seoul, South Korea, and founded in 2018, Upstairs.Inc operates a B2B marketplace specialized for used phones, starting with the used phone price information inquiry service FONGABI and the second-hand phone price comparison service JOONGABI. As a result of analyzing transaction data, users can sell at an average price higher than the existing offline sales. When selling directly through an offline agency a commission is generated by consigning sales to a salesperson.

The company operates two platforms namely, FONGABI which provides a transaction services for both sellers and buyers of used phones through multiple quotation and price comparison services, and JOONGABI PC Manager, an inventory management program that manages information from purchase to settlement of used phone transactions. JOONGABI Mobile, was added as a mobile version of the mid-cost PC manager.

Upstairs.Inc aims to provide reliable used phone transaction information to consumers based on systematically constructed data by creating virtuous cycle structure where consumers can sell used phones at the most reasonable price based on technology.
