Sales and Customer Success Alignment: How SaaS Teams Should Connect

Sansan CS strategist Hisanori Yamada and Well Direction CEO Shunsuke Mukai debate whether CS should own revenue targets, how to fix weak sales handoffs, and why CS is really a PMF acceleration function.

• Mukai argues splitting CS from sales has not clearly improved sales productivity at most companies — many copy the org structure without a defined purpose.
• The root cause of weak sales handoffs is salespeople not internalizing company profit structure: churn shrinks the base their own compensation grows from.
• Mukai ran CS with dual KPIs — churn rate at 60-70% weight and NRR at 30-40% — which drove CS to actively support sales on expansions without abandoning retention focus.
• Both speakers reject CS owning proactive upsell targets: stable customer value delivery is the prerequisite foundation; expansion opportunities should be passed to sales.
• Yamada defines the core CS role as accelerating PMF — observing real use cases, abstracting them into practices, and returning that signal to product, marketing, and sales.
• Reaching exec-level (P&L-impact) customer success takes roughly three years; single-product installations risk informational numbness after that point, requiring deliberate re-engagement cycles.
• The linear The Model diagram (marketing → sales → CS) is misleading; CS sits at the center of a feedback loop and should feed live customer intelligence to all functions continuously.
