How we got started? - We saw a gap in the healthcare industry, where nurse call systems were lacking a modern touch. 4Call was developed as a middleware that served communities economically while also providing a future-proof solution. Our team created a software platform that works with existing hardware, so installation is fast and simple. Where we are going? - Today, we have built a platform for seamless staff-to-resident communication. With constantly changing technology trends, we are moving to the space that forms an intersection between healthcare and hospitality. We work with leading senior housing providers to position themselves as “standouts” from the pack by providing hybrid models of care and hospitality.
