Knock is a platform designed to enhance notification experiences by providing tools for engineering and product teams, with a particular focus on crafting an effective onboarding process that quickly immerses new users. The company emphasizes a self-service approach, allowing users such as developers and product managers to independently explore Knock's offerings, which requires a robust onboarding flow capable of addressing user questions preemptively. The onboarding strategy is centered on guiding users to a "magic moment"—sending their first notification—through a streamlined, context-driven process that integrates both in-app and out-of-app resources. The onboarding flow is designed with focus and discipline, featuring a clear progression and easy navigation back to onboarding materials, inspired by practices from companies like Stripe and Shopify. Knock's strategy also incorporates external elements such as sign-up flows, invitation emails, passwordless authentication, and welcome notifications to ensure users find value and remain engaged. This comprehensive approach not only accelerates user engagement but also provides crucial feedback for product improvement.
