Does the CS team own the Upsell/Cross opportunity?

Scott Hair

I'm new to the forum and I'm sure this question has been asked by others.  I'm curious to learn from other SaaS based subscription software companies as to whether or not their CS team owns the upsell/cross-sell opportunity along with securing the existing renewal?  Or does the CS team perform lead generation then pass the upsell/cross-sell over to sales?  

If the later, how successful have you been and what are the pros/cons that you've experienced?   

If you can provide a little background on your company as context to your response, that would be great -  Company Size (Annual Revenue, Employees, CS team), Renewal Rate, Years in Market.  Market materity/competitive landscape are drivers that I see in determining the vision for CS.

Thank you in advance for your response!
