Knock is a developer-first platform that enables product and engineering teams to implement cross-channel messaging without building notification infrastructure from scratch. The platform handles real-time in-app feeds, chat integrations, and other messaging channels, with integrations that can be shipped in under an hour.
The company operates as a remote-first organisation, a structure it has maintained since its founding. Its culture emphasises focus and autonomy over physical presence, granting individual engineers high agency and ownership over initiatives. The technical approach is described as "APIs all the way down," reflecting this philosophy in both the product and internal engineering practices.
Knock's work sits at the intersection of notification infrastructure, messaging systems, and API development, serving teams within the software development and product engineering sectors.
