Alpha Kappa Psi is one of the better know business fraternities. There is also Delta Sigma Pi, Phi Theta Pi and Phi Chi Theta.
There are many listed on the Professional Fraternity Association website:

There are also some honorary business fraternities, but I can't find a website for them.

If you have to go around telling everyone you're in charge you're not
much of a leader.
