What Makes a Customer Success Platform Indispensable in Tight Budget Times?

A recent conversation with a Customer Success leader got me thinking. They told me they had previously invested in a dedicated Customer Success platform but eventually removed it as part of a cost-cutting initiative. It raised an interesting question: If budgets tighten tomorrow, which Customer Success tools survive? The answer probably isn't the tool with the most features. It's the tool that becomes part of how teams work every day. I'd be curious to hear from CS leaders: What makes a Customer Success platform indispensable inside your organization?
