GameChanger is a mobile app and website that provides an easy scorekeeping solution for amateur sports teams, allowing coaches to save time and provide customized alerts to families and fans via text messages sent through Twilio SMS. The company initially focused on baseball, signing up over 45,000 amateur teams, but now sends nearly two million SMS updates a month. Choosing Twilio's API and service was critical in GameChanger's ability to scale, allowing the platform to handle increasing volumes and switch seamlessly between regular telephone numbers and short codes required for high-volume messages. With Twilio's international and voice capabilities, GameChanger plans to expand into overseas markets, including basketball and other amateur sports, with the goal of reaching billions of people across 150 countries.
