What are the biggest surprises when going from a company where customer success was established to one where you have to establish customer success?

My journey was the other way around. I started at a company where CS was brand new, and then came to a company where CS was established.

Looking back, here are some interesting findings.

• Perceptions of what Customer Success is/isn't vary widely, even if the function already exists at the company. When CS doesn't exist yet, there's an explicit need to educate the executives, sales reps, product org, etc. on what the team will do and the results they will drive. At a company where CS is established, that need for ongoing education still exists-- it just takes a different flavor over time.
• When there's no Customer Success (and even when there is), information on customers can be scattered all over the place. That's why we prioritized getting a CS tool early on, so if nothing else, we would have one place where customer documents, interactions, health, etc. were kept. It takes time to manage that change (put info here, not in your notepad) but it's worth it.
• If Customer Success hasn't existed, the company may be getting its first taste of churn (what prompted them to create Customer Success anyway?). That first taste of churn is bitter, and chances are the data and workflows around risk mitigation and learning from churn aren't well built out. This is an area to invest early- capture the reason codes, build a churn forecasting process, and educate everyone on churn and risk. Moves you make today may take 6+ months to have an impact so make sure to set expectations.
