In 2023, Knock experienced significant growth, quadrupling its revenue, tripling its customer base, and expanding its team while shipping 34 product updates that enhanced its notification infrastructure platform. Notable developments included the release of the Knock CLI and management API, allowing developers to manage notification logic within their codebase, and the launch of Workflow Builder 2.0, which introduced advanced workflow capabilities. The company also expanded its API offerings with new features like subscriptions, schedules, and translations, catering to diverse use cases across various industries. Knock's focus on delivering efficient, customizable notification solutions resulted in a decrease in notifications sent per user, reflecting enhanced user experience. As Knock enters 2024, it plans to deepen integration with developer workflows and further enhance its notification engine, while maintaining its emphasis on creating impactful, customer-focused products.
