Guillermo Lopez traces a nontraditional path from engineering and IT consulting into finance after earning an MBA in Chicago. At American Express, he pursued breadth across FP&A, pricing, and regional roles, learning to be data-driven and comfortable deciding with imperfect information. A formative assignment with Visa’s acquired fintech Tink taught him speed, client centricity, and operating without big-company support. Now as CFO of dLocal, he balances growth with compliance, FX, and settlement complexity across emerging markets, prioritizing cash conversion, disciplined capital allocation, and practical AI use in reconciliation and analysis. He also stresses seeking perspectives from unexpected stakeholders before calls.
