What works at $5M ARR breaks at $100M. Tailor everything.
There is no single customer success playbook that works for every company. A startup with a handful of CSMs serving SMB customers has very different challenges from an enterprise business managing a few hundred strategic accounts. Team size, customer profile, product complexity, and stage of growth all shape what good customer success looks like. The best strategies are built around your own reality, not someone else's. Best practices without context are just guesses.
A playbook that works for a company with $100M ARR can create unnecessary complexity for a company at $5M ARR. Likewise, a process designed for a lean startup will eventually break as the business grows. Every customer success practice has a context where it works best. The goal is not to copy best practices. It is to understand why they work and decide whether they fit your customers, your team, and your stage of growth.
The same principle looks different at every stage. Calibrate the expectation to where the team actually is.
The team adopts ideas from blogs, conferences, vendors, or previous employers with little adaptation. New processes are introduced because they worked somewhere else, not because they solve the team's biggest challenge. Customer success is largely driven by intuition and trial and error.
The team starts adapting its customer success approach to its own business. Different customer segments receive different experiences, and new processes take team size, customer needs, and available resources into account. Instead of copying playbooks, the team chooses practices that fit its current stage of growth.
Customer success strategy is built around the company's own data, customers, and business goals. New initiatives come with a clear rationale for why this practice fits this team at this stage, not just that it worked somewhere else. The team regularly reviews what is working, removes what is not, and updates playbooks based on real outcomes data. When an approach consistently underperforms for a specific segment, it gets revised. Strategy becomes self-correcting rather than a fixed library of inherited practices.
