One of Shy Baldwin’s agents.

S4E5 - Lou and Ken invite Susie and Midge to Shy’s wedding so that they can bribe them into signing an NDA about Shy’s sexuality. They also reveal that Shy is signed to act in Billy Wilder’s next film, and that they used Midge’s show at the Apollo to push Reggie and the band out so they could have full control over Shy. Midge turns down the offer, and leaves in a rage.

S5E7 - Ken loses big to Susie in a poker game with Mike, Vic and Pete. Upset, Ken cries in the bathroom.

LOU: I want you to meet my associate, Ken Bruni. Ken is Shy's new agent over at MCA.
KEN: Very nice to meet you, ladies. Enjoying the party?
– S4E5

KEN: Just another minute of your time. We understand you and Shy got pretty friendly on tour and that maybe you saw some things. One thing in particular that occurred on a boat. We know that you thought you were helping him, so the way it ended up with you on the tarmac that night, it doesn't seem right. We want to make it right.

MIDGE: You want to give me two thousand dollars?
KEN: In exchange for your signature on a legal agreement stating that you won't disparage or besmirch Shy Baldwin in any way, publicly or privately.
MIDGE: You invited me so you could bribe me?
KEN: It's not a bribe. It's an agreement.

KEN: Raise you ten.
SUSIE: I raise your raise.
KEN: Are you raising my raise just to raise my raise?
SUSIE: Yes.
KEN: That's not how you play. Mike.
SUSIE: What do you think he's going to do?
KEN: Fine. Call. Pair of kings.
SUSIE: Hmm. Pair of threes. Oh, and another three.
KEN: Fuck you!
