Wallet
All Digital Discounted Fueling at your Fingertips
At a glance
Took a new digital fuel-payment product from concept to market, turning one of trucking's largest expenses into a mobile savings and security tool.
The challenge
Fuel is one of trucking's largest expenses, but it was managed with physical cards and manual tracking that exposed fleets to fraud and missed discounts.
What I led
Set the product vision and UX direction, ran innovation labs, user journeys and low- to high-fidelity prototypes, and partnered with the CPO, CTO and payment partners through go-to-market.
The outcome
Launched an all-digital fuel wallet with virtual cards, real-time tracking and fuel discounts, built into Transflo's mobile ecosystem.
