Exploding onto the scene about a decade ago, groupbuying service companies have become a force in the eCommerce space. Enticing customers with exclusive deals and discounts on goods and services from cell phone cases to all-inclusive resorts, these timesensitive deal websites have made their mark on their industry. For one such company, the secret to their success is data. Real-time location sharing gives an opportunity to display geographically relevant deals; historic transactional data allows past purchases to dictate what offers show up in emails; and customer behaviors are tracked, noting which offers are browsed and purchased. The data collected and analyzed helps their engineers to build the ultimate experience for their customers—and all of it depends on timing, technology, and delivering the right offer to the right customer to drive business.
