As a Client Success & Retention Specialist, I managed a portfolio of 80+ SMB hospitality clients across English, Spanish, and French-speaking markets. I focused on reducing churn and improving long-term loyalty by proactively identifying at-risk accounts, offering personalized solutions, and resolving cancellation requests quickly—retaining 40–45% of clients who initially wanted to leave. I collaborated closely with Sales, Product, and Support teams to streamline onboarding, improve customer journeys, and increase engagement. By using data to anticipate churn risks and designing tailored retention strategies, I consistently helped boost satisfaction and contributed to higher Net Promoter Scores (NPS).
