Upside (formerly GetUpside) is a U.S.-based marketplace for in-person purchases at gas stations, grocery stores, and restaurants. Its two-sided platform connects consumers looking to earn cash back on everyday purchases with businesses looking to grow by attracting new customers and driving repeat visits. Consumers earn cash back that they can easily cash out to a bank account or their choice of gift cards at any time. Retailers pay only for proven incremental transactions, not for impressions or clicks. The app is free to download with no subscription required. To date, consumers have earned over $1 billion in cash back, and retailers have earned $3 billion in incremental profit.
