Nstream
A faster way to build streaming data applications
Upside gives local merchants a way to attract new customers and compete with e‑retailers. When restaurants, grocery stores, gas stations, and convenience stores join Upside, the company uses anonymized transaction data to create personalized cash-back offers, which are delivered via the Upside mobile app and partner apps. Individual consumers are tracked against a control group to measure Upside’s effect on their expected spending, and merchants only pay when they earn profit they would not have seen otherwise.
