Strategic Customer Success Leadership for B2B SaaS

Your customer success is struggling. Retention is slipping, expansion revenue is flat, or your CS team can't keep up with growth. These problems happen when companies outgrow their customer success operations.

I'm Amy Cass. I spent 7 years as Senior Client Partner at Meta managing $150M+ portfolios and 10+ years building CS operations that drive revenue, not just prevent churn. Now I help B2B SaaS companies build customer success that scales.

Proven results from real experience:

  • Improved renewal rates 16% and grew ARR 20% at Series A SaaS company

  • Managed $150M+ enterprise portfolio at Meta

  • Built CS team from 1→17 members, reduced onboarding time 77% at growth-stage SaaS

  • Drove 110% YoY revenue growth across 160+ global accounts at ad tech startup

  • Led teams across NA, APAC, and EMEA managing Fortune 500 strategic relationships
