I am not married to these colors, but I am drawn to a combination of the following 3:
#303754, #4A73AD, and #4AD3B8. That said, I am ok with expanding on this palette if you feel the design calls for it.
Our Ideas and Additional Information:
I chose the name Link because this is pulling data from multiple sources to help create insight for the client. And, as mentioned in the description, the product makes heavy use of graphs and data visualization. So, while I am open to other ideas, I am drawn to something that incorporates the concepts of bringing multiple things in to create graphical insights.
