The challenge

After a strategic shift, Teamleader handed its Customer Success team ownership of upsell and renewal targets overnight. Strong product knowledge, zero background in commercial conversations. The sudden responsibility created real anxiety about holding discovery calls or raising upsell with existing customers.

The solution

  • Built a custom commercial CS training program around Teamleader's own customer conversations, not a generic upsell script
  • Ran embedding sessions alongside the training so new skills got used in real calls, not just discussed in a workshop
  • Designed repeatable structures for onboarding, nurture, and upsell so the approach outlasted the training itself
  • Worked deliberately on the mindset shift from support function to proactive commercial owner

The results

  • NPS of 78 (9.05/10) from the CSMs who went through the program
  • Team tracking 20% above its upsell targets post-training
  • New onboarding, nurture, and upsell structures implemented and running
  • Stronger, more collaborative relationships with customers reported across the team
