Belly, a Chicago-based startup offering a unique customer-loyalty program, was experiencing significant growth but wanted to maximize its mobile app installs. To address this, the company's CTO, Craig Ulliott, used the Twilio SMS API to build a small app that sent users an SMS with a link to download the Belly mobile app after they signed up for the program. This addition significantly reduced friction and increased the download rate by 200%, making it easier for customers to participate in the program.
