How to Hire a Customer Success
A comprehensive guide to evaluating Customer Success candidates — the metrics that matter, the questions to ask, and the mistakes to avoid.
What Great Looks Like
- Drives net revenue retention above 110% through strategic account expansion
- Has built scalable CS motions: health scores, playbooks, QBR frameworks, risk management
- Balances proactive value delivery with reactive support — doesn't just wait for fires
- Can quantify their impact: churn prevented, expansion revenue driven, NPS improved
- Understands the product deeply enough to be a trusted advisor, not just a relationship manager
- Has experience building or scaling a CS team, not just individual contribution
Metrics That Matter
Net Revenue Retention
110-130% for enterprise, 100-110% for SMB
Logo Retention
90%+ for enterprise, 85%+ for SMB
Expansion Revenue
Measurable contribution to ARR growth
ARR Under Management
Aligned to portfolio size for segment
NPS / CSAT
Improvement trend matters more than absolute number
Time to Value
Measurable reduction in onboarding time
Questions to Ask
- 1
Walk me through how you've managed a book of business. How did you segment accounts and prioritize your time?
- 2
Describe a customer who was at risk of churning. What signals did you see, what actions did you take, and what happened?
- 3
How do you drive expansion revenue? Give me a specific example of identifying and closing an upsell opportunity.
- 4
Tell me about a QBR that changed the trajectory of an account relationship. What made it effective?
- 5
How do you balance the needs of your largest accounts with the rest of your portfolio?
Red Flags
- Can't tie their work to retention or expansion numbers — only talks about "relationships"
- No experience with health scoring, risk management, or proactive intervention
- Treats CS as support rather than a strategic revenue function
- Has never had to manage churn conversations or negotiate renewals
- No cross-functional collaboration experience with sales, product, or engineering
- Reactive approach: waits for customers to escalate rather than identifying risk early

Late / Public
Specialized CS roles: onboarding, strategic, scaled/digital CS, and CS ops as distinct functions.
What Changes by ACV
Self-Serve / SMB
Scaled and digital CS. One-to-many programs, automated health scoring, and tech-touch onboarding.
Mid-Market
Pooled model with defined touch cadences. Balance portfolio size with meaningful engagement.
Enterprise
Named accounts with deep, strategic relationships. QBRs, exec sponsors, and multi-year expansion plans.
Common Hiring Mistakes
- 1Treating CS as a support extension rather than a strategic revenue function
- 2Not giving CS ownership of expansion revenue — creates misaligned incentives
- 3Hiring for relationship skills only without evaluating commercial acumen
- 4Setting book sizes too large for the segment (enterprise CSMs with 50+ accounts)
- 5Not building CS ops infrastructure early enough — health scores and playbooks compound over time
