Looking for: White Label Client Portal CRM Solution

Good Morning everyone,

I'm looking for a White Label Client Portal Solution that has a Client Facing CRM.

Basically, a Login where they see our Branding, and the Live Prospects ready to be spoken to, we have over 20 clients and are looking to streamline our process – each of them would have their own respective CRM view with prospects only they could see.

Any suggestions?

Thanks
