You are planning on founding the software platform company $$ChatBot$.$ It offers the app DirectChat,

which is an instant messenger that can be downloaded to Android$-$ and iOS$-$based smartphones. Its

key purpose is to allow for text$-$message exchange between its users. The ChatBot platform also allows

for the download and use of third$-$party apps within the messenger DirectChat, which are free of

charge for the users of DirectChat. These third$-$party apps are voluntarily developed by external

software developers and generate revenue by the display of advertisements within them. The ChatBot

platform aggregates this ad space and offers it to interested advertisers. Hereby, ChatBot acts as an

intermediary and keeps $50\%$ of the revenues from the advertisements. The remaining $50\%$ of

advertising revenues are given to the developers of the app in which the respective advertisement is

displayed to the user.
