FAQs

What is SEDDI?

SEDDI is a 3D apparel technology company that helps apparel distributors, decorators, brands, and manufacturers design, visualize, and produce apparel more efficiently in the cloud, with accurate digital fabrics, garments, and lifelike 3D mockup capabilities.

SEDDI currently has three products:

Decorator – online 3D mockups for branded apparel, connecting blanks, distributors, decorators, and print shops, from proof to production.
Author – cloud-native 3D apparel design and engineering platform for collaborative, technically accurate garment creation.
Textura – AI-driven digital fabric creation and management with science-based physics and quality assurance workflows across suppliers.

Who is SEDDI for?

SEDDI supports the branded apparel ecosystem—brands, promotional product distributors, decorators, screenprinting operations, and manufacturers—looking to streamline approvals, reduce sampling costs, and sell faster with impactful visuals.

Who uses SEDDI?

Teams at promotional products distributors, decorators, branded merchandise companies, and blank and branded apparel manufacturers, that need faster proofs, faster sales, fewer reworks, and more accuracy.

Do SEDDI Products work together?

Yes. SEDDI products are designed to support one another. Textura digitizes fabrics that are used in both Author and Decorator. Author provides advanced 3D style engineering, creating true-to-life garment models. Decorator then uses those models to deliver accurate, production-ready 3D mockups for branded apparel sales. Together, SEDDI’s products digitize the apparel ecosystem—from fabric digitization to finished 3D product visualization—helping brands design, sell, and produce with precision.

Do I have to use all three products?

No. SEDDI is modular. Teams often start with one product that is best suited to their sector in the apparel industry and expand as digital workflows mature.

Is SEDDI cloud-based?

Yes. SEDDI delivers cloud-native tools so teams can collaborate in real time without specialized local hardware.

Do I need special hardware or downloads?

No special downloads; SEDDI runs in modern browsers, with cloud computing doing the heavy lifting (specifics vary by product; see product pages).

What problems does SEDDI solve?

SEDDI Decorator is more than a mockup generator—it helps distributors, decorators, and brands accelerate sales with photorealistic mockups, reduce costly mistakes with operational precision, and deliver production clarity with techpacks that include exact print placement and color codes. By replacing slow sample rounds with accurate digital replicas, Decorator shortens approvals, speeds up production, and helps businesses win more orders.

What makes SEDDI different?

SEDDI spans the full digital apparel pipeline—fabric → garment → mockup—in the cloud. All of our technology is built on physics-grounded digital fabrics, ensuring every style behaves and looks true to life. What truly sets us apart is our partnerships with leading blank apparel brands like BELLA+CANVAS, Gildan, and AS Colour. We create accurate digital replicas of their real styles from the original patterns, so everything from fit to color is precise. This means brands, distributors, decorators, and manufacturers can collaborate with confidence, using assets that mirror real-world apparel.

How does SEDDI improve sustainability?

By replacing rounds of physical sampling with accurate visualizations and physics-backed digital fabrics, SEDDI helps reduce material waste, shipping, and rework.
