Hi limy,
You can go into Admin-> Data connector to check if Adobe has a tie up with particular partner or not. For searching the partner name, please sort it first in Alphabetic order.
Regarding Bronto, I can see there is data connector integration available. Below is the documentation.
Bronto Marketing Platform
Attached is snapshot for data connector window.

For seamless integration, it is always recommended by Adobe to have the integration through Adobe consulting team.
