Overview
The project
in context.
Skydropx is LATAM's leading shipping aggregator. StartxLabs developed mobile fleet management capabilities and merchant integration portals that compare carrier rates (DHL, FedEx, UPS, Estafeta) in real time, generate shipping labels programmatically, and provide end-to-end package tracking for thousands of online stores.
