Software as a service company cannot be defined fully without knowing the acronym "SaaS". Of course, you already know that by now. However, the meaning of "software as a service" is what needs to be figured out. SaaS means that the software is available to the users via internet connectivity—accessed through a mobile app or browser. The software is hosted on the developer's servers. This is in contrast to what a desktop-based model comprises. The use of a desktop-based model entails the installation of software on computers by the individual or company while hosting on their servers.
