Alexandre Sarte's journey from São Paulo to founding Tell Sys in Switzerland began with discovering his great-grandparents' courage fleeing World War I to Brazil. Inspired by their resilience, he embarked on his own international path — securing Italian citizenship, consulting in the UK, and mastering his craft across Europe since 2015.
"Each country shaped my approach: French engagement, Swiss precision, British pragmatism, and Brazilian creativity and speed."
— Alexandre SarteThrough 14 years working across Brazil, the UK, and Switzerland, Alex became a recognised expert in EPM platforms, budgeting, planning, and consolidation. Each country shaped his approach — blending complementary strengths into a consulting philosophy that is both technically precise and deeply human.
