Customer Success
In one line
Customer success is the discipline of proactively helping customers achieve their business goals with your product — increasingly treated as a core SaaS growth engine, not a support function.
Going deeper
Customer success is not 'support that answers tickets'. From day one of the deployment, the CS team defines, with the customer, the business outcomes the product needs to deliver — and then drives toward them proactively.
It became central in SaaS because 70–90% of revenue at maturity comes from renewals and expansions. Post-sale success effectively determines NRR and LTV. Companies with healthy CS programs settle NRR at 110%+ and feel materially less pressure on new logo acquisition.
From a B2B marketing angle, CS is also the biggest single source of case studies, testimonials and references. Organisations that connect CS and marketing with regular interview cadences and asset handoffs tend to outproduce siloed teams on customer-proof content by a wide margin.
