I disagree with your logic.

I think it's not about size but about structure.

Structuring the mini buy out of a 50M company with let's say:
- 10M Senior Revolver
- 10M Senior Term Loan
- 10M High Yield
- 5M Mezzanine
- 15M Equity

is IB to me. Mini-IB but still IB.

On the other hand, a big commercial bank providing a 300M plain vanilla senior loan to a corporation isn't doing IB.
