"Now is the moment for Customer Success to cement its value to the C-Suite by protecting revenue under management, owning retention and renewals, and accelerating expansion with precision. Our unification with Catalyst will make enterprise-grade integrations and AI capabilities a priority and category differentiator as we embrace a new model for driving long-term, customer-led growth," Alistair Rennie, Totango CEO.
