Join Trackstar and Help Power the Future of Supply Chain Tech  The $10T+ supply chain industry runs on fragmented, legacy systems across warehouses, ecommerce platforms, carriers, and more. At Trackstar, we're building the connectivity layer that ties it all together. Trackstar is the universal API for supply chain data. Instead of building and maintaining dozens of integrations across systems, companies integrate once with Trackstar to access a unified data model across multiple verticals — including WMS, commerce platforms, and carriers.
