Security deposit interest

[Nathan G.]

My Chase Business savings account pays negligible interest, and I would like a higher interest bearing account in which to place security deposits so I can keep the interest (in Michigan where this is allowed).

Where is a good place to put security deposits to get significant interest? My personal savings account is with Ally and pays 2.2% APY presently, but I cannot open an account under my LLC there. If I open another savings account there under my name it feels like commingling.
