Vidyard, an online video platform known for serving major brands like Salesforce and Microsoft, significantly improved its notification system by transitioning to Knock, a third-party service, after finding their previous in-house system to be slow and fragmented. This shift allowed Vidyard to drastically reduce the time required to implement new notifications from several weeks to mere hours, enhancing their product-led growth strategy by expediting feature releases and reducing technical debt. The move to Knock enabled Vidyard to eliminate three internal services and improve the overall efficiency and understanding of their notification logic, which was previously a complex and time-consuming process that required coordination across multiple frontends and backend services. By leveraging Knock’s user-friendly APIs and robust developer experience, Vidyard was able to simplify their infrastructure and focus more on their core product, thereby accelerating their ability to experiment and learn from notifications to drive user engagement and growth.
