The list would be the list from this page on a users account (http://getsatisfaction.com/people/nat..., but only companies. It might also be worth doing the same kind of thing for the product tab too though (the 'People' tab should probably also sync with your 'Contacts' on GS).
It might also be useful to display the company's logo/icon on the left of the company's name and have alphabetical separators (similar to the 'Friends' tab on the Facebook app).
P.S - David, how about changing your icon on GS from a cupcake to a photo?
