Mario Muñoz DiazDeLeon

I've spent more than seven years at Banco Santander México improving operations, customer service, SME portfolio performance, and B2B growth through data-driven decision-making.

In my current Sales and Customer Success Manager role, I manage B2B client portfolios through the full customer lifecycle, from onboarding and retention to growth. I design CRM journeys, automations, sales processes, and follow-up sequences that improve conversion visibility, revenue tracking, and response times.

Previously, I led regional branch operations using KPI dashboards, Excel, Tableau, reporting frameworks, SLA management, audits, and cross-functional coordination. My work supported a 130% increase in portfolio revenue, a 98% increase in client retention, a 95% improvement in sales pipeline efficiency, and an 80% improvement in operational efficiency.

I'm focused on strengthening analytics and CRM capabilities to help organizations build scalable processes, stronger customer relationships, and sustainable operational growth.
