Dear Hiring Manager,

I'm applying for the Customer Success Manager role at your company. Over the past three years at Vantik Analytics I've managed a portfolio of 45 enterprise accounts worth $6.2M in ARR, closing last year at 114% net revenue retention against a company average of 102%.

I run quarterly business reviews in Gainsight, track account health against usage and support data, and flag at-risk accounts before renewal conversations start. When our largest account's usage dropped 30% after a champion left, I rebuilt the relationship with the new stakeholder, ran a value-realization workshop, and converted a likely churn into a $180K expansion.

I also built a shared health-score dashboard with product and support that cut our team's time-to-flag on at-risk accounts by half. Your recent move upmarket into enterprise accounts is exactly the challenge I want next, and I'd welcome a conversation about how I can help protect and grow that segment.

Best regards,

Marcus Whitfield
