When discussing customer success for SaaS startups, the conversation focuses mostly on retaining customers and reducing churn. These are two fantastic benefits with meaningful return-on-investment. But great customer success organizations can meaningfully impact another critical part of the customer lifecycle, customer acquisition, by catalyzing evangelists to refer new customers.
Let’s examine a hypothetical SaaS company that acquires 1,000 customers though sales and marketing. Assume a standard 15 month payback period implying a CAC of $1250 per customer or $1.5M in aggregate. Each customer pays $1k annually to use the product. If customer success can convert 1 in 10 of those customers to evangelists, each of whom refers only one other customer that year, the company’s CAC drops by a third.
