On investory.io you have the possibility to "follow" startups. Following a startup means you can separately filter them in your dashboard and you receive e-mail notifications whenever they publish somthing new. Go to "Manage Portfolio" to manage your follows:

After you opened the management page you can see all startups. If the "Status" says "Requested" your invitation hasn't been accepted yet. Click on the green star if you want to follow a specific startup, wich is already connected to your fund. 

In case you have a single account you follow all your startups by default.
If you are part of a group account, you should definitely follow the companies you are responsible for. Only then you can be always up to date with their latest development.
