Mentimeter, a rapidly growing engagement tool used by over 280 million people worldwide, has enhanced its platform by integrating Knock's notification infrastructure to support collaborative presentations. Initially focused on perfecting real-time presentation interactions, Mentimeter shifted towards enabling team collaboration, recognizing the need for effective communication features. By adopting Knock, Mentimeter implemented cross-channel notifications, including in-app and email alerts, in just two weeks, avoiding the significant investment and time required for an in-house solution. This decision allowed them to maintain focus on core product development while providing users with seamless collaboration experiences without notification fatigue. Knock's advanced routing capabilities, analytics tools, and user preference management have enabled Mentimeter to enhance user engagement and plan further expansions, such as integrating notifications with Slack and MS Teams. The partnership with Knock has been pivotal in supporting Mentimeter's growth, allowing them to rapidly deploy new features and improve user interaction without the burden of managing complex notification systems internally.
