@happinesssumdins
I grow SaaS and B2B customer retention, adoption, and advocacy through data-driven account management.
What I'm looking for
I'm currently managing enterprise education-sector accounts at Nigerian Armed Forces Resettlement Centre, improving customer retention by 20% and product adoption by 15%.
I work closely with Product and Sales to resolve escalations, reduce churn, and uncover renewal and expansion opportunities. This collaboration contributed to a 25% reduction in customer churn.
At Hondo, I strengthened onboarding, customer communication, and feedback analysis, helping raise NPS by 18% and reduce onboarding time by 25% through a knowledge-base project.
I use HubSpot and Salesforce to monitor account health, identify risk early, and turn customer feedback into practical improvements. I'm focused on building trusted client relationships that create long-term advocates.
