Vidyard, an online video platform, transitioned to using Knock for its notification infrastructure to enhance its product-led growth strategy and improve operational efficiency. Previously, Vidyard's in-house notification system was slow, complex, and fragmented, requiring weeks to implement changes, which hindered their ability to rapidly develop and release new features. By adopting Knock, Vidyard significantly reduced the time needed to introduce new notifications from weeks to mere hours or minutes, removed three internal services, and simplified their infrastructure related to message routing, preference management, and push notifications. This change not only expedited their feature deployment process but also allowed the team to focus more on core product development and experimentation with notifications to drive user engagement and product growth. The collaboration with Knock proved successful, meeting all project milestones and enabling Vidyard to efficiently launch new features such as Vidyard Rooms.
