- Knock is a flexible API and dashboard for powering delightful product notification experiences. It helps you ship faster, iterate on your product messaging, and scale your notifications for the long-term. We built product notifications so you don’t have to.
- Power your product notifications using customer data platforms (CDPs) such as Segment or RudderStack, and reverse ETL platforms such as Hightouch, Census, or Polytomic.
