knok is a digital health company founded in 2015 and headquartered in Portugal. It builds an API-first, white-label platform that enables healthcare providers to deliver branded telemedicine services, including video consultations and coordinated home doctor visits. The platform's core component, the Patient Journey Engine, manages and personalises digital care flows for each provider's patient population. To date, it has facilitated over 2.5 million clinical interactions across more than 12 countries.
The technical stack centres on platform and API development, with an emphasis on configurability and integration. Key engineering domains include video conferencing infrastructure, white-label SaaS architecture, patient journey orchestration, and home health logistics and care coordination. The API-first design is intended to let healthcare clients embed knok's capabilities into their own products and workflows rather than adopting a fixed end-to-end solution.
knok's customers are healthcare providers - insurers, hospital groups, and similar organisations - that want to offer digital care experiences under their own brand. By handling the underlying infrastructure for virtual and in-home consultations, knok positions itself as the technology layer behind those patient-facing services.
