In 2022, Knock significantly expanded its reach and capabilities, transforming from a product behind a waitlist to a trusted provider of notification solutions for hundreds of companies, including notable enterprises like Vercel and SafetyCulture. Throughout the year, Knock introduced 34 changelogs that enhanced its notification engine, offering features such as a visual template editor for emails, support for over 15 new channels, and enterprise-ready functionalities like audit logs and SSO. The company also focused on enriching its API with new abstractions to support diverse notification use cases, enabling real-time user identification and seamless integration with CDPs and reverse ETL platforms. As Knock looks forward to 2023, it plans to further refine the developer experience, integrating features like a management API, CLI, and Git-based source control, while advancing system-wide intelligence to optimize notification workflows based on user preferences and engagement.
