For Board Manufacturers
Your Invisible
Supply Chain.
The OEM source behind industry-leading iSUP systems. 20,000+ sets in stock. 100% white-label. We build the parts; you build the brand.
Our Commitment
We Are Your Warehouse,
Not Your Competitor.
We understand the concerns of working with another board manufacturer. Our custom fin and component division operates with complete separation — your business stays protected.
NDA on Day One
Zero Finished Boards
We strictly supply components. We never pitch finished SUPs to your clients. Your customers remain yours.
100% White-Label
No Daywin logos on any component. Our parts are designed to be your invisible infrastructure — seamlessly integrating into your production.
Data Isolation
Complete confidentiality on your volumes and specifications. NDA signed on Day One — before any samples are shipped.
Cloud Warehouse
Never Stop Your Production Line.
Don't let a missing $5 box delay a $500 board shipment. We act as your JIT (Just-In-Time) cloud warehouse — massive inventory, rapid dispatch.
