Knock.app is a technology startup that provides a robust and scalable notification system for businesses. The company's primary offering is a flexible and reliable notifications infrastructure that is designed to scale with the needs of its clients. This infrastructure is powered by an API that allows businesses to engage users, manage notification preferences, and power cross-channel workflows.

Knock.app's services are primarily targeted at developers, providing them with a unified API, SDKs in all major languages, comprehensive documentation, and a CLI to work with Knock resources locally. This allows developers to focus on their core tasks, while Knock.app takes care of the notification system.

In addition to its API, Knock.app also offers pre-built, real-time enabled components for in-app notification experiences. These components are backed by Knock’s powerful notifications infrastructure, providing businesses with a ready-to-use notification system.

Knock.app operates in the technology market, serving a wide range of clients, from small businesses to large enterprises. The company's business model is based on providing its notification infrastructure as a service, which means it generates revenue by charging its clients for using its services.
