PocketBase was created to assist building self-contained applications that can run on a single server without requiring to install anything in addition (see Presentator#183 ).
The basic idea is that the common functionality like crud, auth, files upload, auto TLS, etc. are handled out of the box, allowing you to focus on the UI and your actual app business requirements.

Please note that PocketBase is neither a startup, nor a business. There is no paid team or company behind it. It is a personal open source project with intentially limited scope and developed entirely on volunteer basis. There are no promises for maintenance and support beyond what is already available (you can explore the Roadmap to get a general idea where the project is headed but there are no fixed ETAs).
