Customer Success (CS) is more than just support—it’s a strategic function that drives retention, expansion, and revenue growth. Top SaaS companies prioritize CS by structuring it effectively within their GTM teams.
Where Does Customer Success Sit in the Organization?
<$250M ARR: CS often reports to the Chief Revenue Officer (CRO), operating closely with sales.
$250M+ ARR: CS transitions to a separate function, often reporting directly to the CEO.
This shift reflects the increasing importance of customer retention at scale. When CS reports to the CEO, it gains more influence over company-wide strategy, aligning product and sales efforts to enhance customer experience.
Scaling Customer Success: Key Metrics
CSM-to-ARR Ratio:
Early-stage: 1 CSM per $1-2M ARR
Growth-stage: 1 CSM per $5M ARR
Premium Customer Support:
At $25M+ ARR, companies introduce paid CS tiers offering benefits like 24/7 support and dedicated account managers.
Why Customer Success Matters
Retention is cheaper than acquisition. Investing in CS ensures high customer lifetime value (LTV), leading to sustained revenue growth.
