About Guido
Senior Customer Success Manager with experience managing enterprise SaaS portfolios across EMEA & LATAM, driving retention, expansion, and long-term customer value.
I’ve worked closely with Sales, Product, and Support teams to build scalable customer success strategies, including onboarding frameworks, success plans, QBRs, and proactive engagement models to reduce churn and increase ARR.
Throughout my career, I’ve managed €5M+ in ARR, partnering with enterprise clients to align business outcomes with technology solutions and consistently improve customer health and satisfaction.
I’m now focused on supporting SaaS companies as a fractional or project-based CSM, helping them build or optimize their customer success function with a pragmatic, results-driven approach.
