Dennis Chang

FPicture a landscaping crew in July, three trucks scattered across a county, and a fuel card that gets swiped eleven times before noon. One of those swipes is a personal pickup filling up on the company's dime. For most fleet operators that swipe is invisible until the statement lands weeks later. Dennis Chang built RoadFlex so the swipe gets flagged the moment it happens - the card checks the truck's GPS, sees the vehicle is parked two miles away, and declines. That is the whole pitch, and it is more interesting than it sounds.

RoadFlex is a Visa fuel and expense card built for the fleets nobody writes magazine profiles about: HVAC vans, delivery rigs, passenger-transport vehicles, landscaping trucks. The platform pairs real-time transaction controls with telematics validation, automated reconciliation, and AI-flavored fuel analytics. Chang co-founded it in 2021 with Greg Soh, who runs engineering as CTO, and has grown the team to roughly thirty people. The company operates as Openlane Technology Corporation, doing business as RoadFlex.

Here is the strange specific that explains him better than any title: his LinkedIn handle is dennisfromperu. Chang is Taiwanese-Peruvian, raised in Lima, a graduate of Colegio Newton who grew up trading between three languages - Spanish at school, Chinese at home, English everywhere it mattered later. That trilingual, tri-cultural upbringing is not a footnote. It is the reason a man who could have built almost anything chose to build for the operators who run vans and trucks and rarely get software designed with them in mind.

From materials science to McKinsey to the power grid

Chang's resume reads like a series of detours that turned out to be the route. He went to Stanford and collected two engineering degrees - a bachelor's in materials science and engineering, then a master's in management science and engineering. He spent time as a management consultant at McKinsey & Company, did product management at Alchemist Accelerator, and handled product and partnerships at StartX. Each stop taught him a different dialect of the same language: how to turn a messy operational problem into something a machine can measure.

Then he co-founded his first company. From 2017 to 2019 he led Buzz Solutions, which used computer vision and predictive analytics to inspect electrical-grid infrastructure - teaching power lines, in effect, to report their own faults before they failed. It was unglamorous, infrastructural, and quietly important. The same description fits RoadFlex. There is a pattern here: Chang keeps choosing the problems that sit underneath the things everyone else takes for granted.

The investor who became the founder

Before RoadFlex, Chang spent years on the other side of the table. He was a venture capitalist at UL Ventures, backing companies in supply chain, sustainability, and cybersecurity, and a Venture Partner at Republic. Investors are professional pattern-matchers; they spend their days deciding which problems are worth a decade of someone's life. Chang looked at his own pattern board and found the most underserved square sitting in fleet payments - a category dominated by legacy fuel-card incumbents who treated drivers like cost centers and operators like afterthoughts.

So he crossed over. The keywords that orbit RoadFlex tell the story of what he is actually building: transaction alerts and lockouts, fuel type and location validation, automated fuel tax reporting, driver and vehicle benchmarking, out-of-network acceptance, telemetry-based purchase validation, instant card issuance. It is a long list, and every item on it is a small act of giving a small fleet the kind of control that used to belong only to enterprise logistics giants.

Why fleets, why now

There is a version of fintech that gets all the attention - consumer neobanks, crypto rails, glossy buy-now-pay-later apps. RoadFlex is not that. It is the version that runs on diesel and reconciliation reports, that measures success in fraud caught and hours of bookkeeping saved. Chang's bet is that the future of fleet fintech runs on telematics rather than trust. A card that can prove a fill-up happened at the right place, in the right vehicle, for the right fuel is worth more to a thirty-truck operator than any rewards program.

His aspiration, stripped of jargon: make fleet fuel and expense spending fully transparent and effectively fraud-proof, and hand the controls that once required an enterprise IT budget to the people running vans out of a single garage. It is a deeply practical ambition from a deeply practical builder - the kind of person who studied how materials fail, learned how grids fail, and now spends his days studying how fuel budgets quietly leak.

Catch him mid-stride and that is what you see: a Lima kid turned Stanford engineer turned consultant turned investor turned founder, now obsessed with the unglamorous machinery that keeps American fleets moving. The trucks are not interesting. What Dennis Chang does with their data is.
