it's not really a startup. From:

Why have I never heard of Old Glory Bank? Old Glory Bank was previously called First State Bank in Elmore City, Oklahoma, which was established in 1903. We recently acquired First State Bank and changed its name to Old Glory Bank. There is a new group of owners, executives, and board members, who have decades of experience in banking and technology. With our great mobile banking solutions, Old Glory Bank will be your hometown bank, no matter where you call home.

I believe they are trying to take it national by providing a significant online presence.
