Placement Agents/Private Placement Info Request

I was hoping someone could provide a bit of info on the big placement agents out there for various types of funds (HF, PE, RE, etc.) and provide a bit of an overview of the major players in the industry as well as what general exits and b school placement looks like. While there's a bit of info out there, most of it is relatively out of date or behind paywalls. Mostly just looking for general info
