'Ally' is not a successful startup. Ally is the rebranded GMAC, whose founding dates back to 1919. GMAC was renamed (and officially transformed into a registered bank) as part of a series of changes which included receiving over $16 billion in federal bailout assistance.

Though I suppose 'Ally' was a spectacular renaming, and their advertising is working, if it gives people the impression Ally is a can-do startup!
