Senior Customer Success Manager driving churn reduction, retention, and ARR growth across B2B SaaS partnerships.
What I'm looking for
I’m a results-driven Customer Success Manager with 11+ years of experience across B2B SaaS, EdTech, and operations, focused on delivering measurable outcomes from onboarding through renewal. I’ve driven churn reduction and sustained 95% client retention by building disciplined customer lifecycle management, customer health monitoring, and Voice of Customer (VoC) feedback loops.
I lead cross-functional execution—often with 50+ team members—to strengthen account expansion through renewals, upsell & cross-sell, and Quarterly Business Reviews (QBRs). With hands-on expertise in Salesforce CRM (and Microsoft Dynamics CRM), plus data-driven success planning (including Generative AI tools), I help teams improve NPS and accelerate ARR growth while ensuring consistent SLA adherence.
