Which US Brokerage Uses IB-LLC As Clearer?

The title says it all: Which brokers are using IB as their clearing firm? Any hints?

Thanks

 

We use IB for LVX clients and Wedbush for other software.

Thanks Robert. I have posted your answer on a European board.

 

Zions Direct (a subsidiary of Zions Bank) uses IB for clearing.

 

Does it have to be IB? We take foreign accounts with custody at Wedbush.
