our call
Start with Syte — highest vibe code, weakest moat.
Sizebay
Building the user-facing modal and body-matching calculation engine takes a few days with AI. However, running a production service requires standardizing chaotic, non-standard merchant size charts across thousands of SKUs and maintaining precise fit models at scale.
you can rebuild
- Modal-based interactive step-by-step body measurement questionnaire.
- Mathematical matching algorithm comparing user dimensions to garment specs.
- Shopify storefront widget injection script and LocalStorage profile persistence.
- Basic admin portal for manual size chart JSON/CSV uploads.
- Fit preference adjustment sliders (Tight vs. Loose fit bias).
what you lose
- Pre-mapped sizing databases for thousands of major fashion brands and suppliers.
- Machine learning fit algorithms refined by millions of historical return/conversion data points.
- Turnkey integrations with major e-commerce platforms and headless storefront framework adapters.
- Automated onboarding tools that digest merchant size tables without manual developer intervention.
real moats
- Historical cross-brand fitting datasets mapping real consumer return rates to specific garment measurement patterns.
- Proprietary database of standardized size charts covering tens of thousands of global fashion items.

Syte
Syte was built back when image recognition required custom computer vision models and specialized AI teams. Today, open-source vision encoders like CLIP and multimodal LLMs make high-accuracy visual search and shop-the-look tagging achievable in a weekend build.
you can rebuild
- Camera search widget for e-commerce storefronts
- Visual similarity recommendations on product detail pages
- Shop-the-look photo tagging and bounding box matching
- Automated product attribute tagging from images
- Visual merchandising and aesthetic product groupings
what you lose
- Pre-built native connectors for enterprise stacks like SAP Commerce Cloud and Salesforce Commerce Cloud.
- Custom enterprise SLAs and dedicated customer success managers.
- Zero-code automated tagging dashboards for non-technical merchandising teams.
- Historical search analytics and visual intent reporting out-of-the-box.
