A service that offers specialized assistants in many areas, like doing online research, dealing with invoices, updating blogs, calling clients, etc. Each specialized assistant is the top at what they do, so training them to execute on your specific needs is easier and faster. You can have a fixed specialized assistant in many of these areas and use them when you need to, regularly or from time to time.
