# Dennis Chang

> Dennis Chang is the co-founder and CEO of RoadFlex, a Visa fuel and expense card built for the unglamorous fleets that keep America moving - HVAC vans, landscaping trucks, delivery rigs. A Taiwanese-Peruvian who grew up in Lima and trades in three languages, he studied materials science and management engineering at Stanford, consulted at McKinsey, co-founded an AI grid-inspection startup, and spent years as a venture investor before deciding the most interesting problem in fintech was hiding at the gas pump: fuel fraud. RoadFlex pairs real-time transaction controls and telematics validation to stop a driver from filling a personal pickup on the company dime.
