our call
Start with Sizekick — highest vibe code, weakest moat.
Fit Analytics
While building the frontend quiz widget takes a few hours, Fit Analytics' value comes from billions of sizing data points across thousands of apparel brands. A custom AI prompt cannot replicate cross-brand size translation (e.g., 'You wear L in Nike, so buy M here') without access to global fit databases.
you can rebuild
- Interactive frontend size recommendation modal
- Static size chart overlays on Product Detail Pages
- Basic user input collection (height, weight, fit preference)
- Local browser storage of user size preferences
- Post-purchase return reason tagging for size issues
what you lose
- Cross-brand reference engine translating sizing across 1,000+ global brands
- Machine learning models trained on hundreds of millions of verified purchase/return outcomes
- Garment stretch, fabric weight, and silhouette micro-adjustments
- Automated continuous re-calibration of SKU sizing based on real-time return signals
- Enterprise-grade conversion and return reduction benchmarking analytics
real moats
- Proprietary dataset of over a billion garment measurements and return logs
- Cross-merchant network effect where shopper fit profiles carry across participating sites
- Deep technical integrations with garment tech specs and enterprise apparel PLM systems
Sizekick
Building a rule-based questionnaire size guide takes a weekend. Reconstructing 3D body measurements from 2D mobile camera feeds with GDPR-compliant biometric privacy controls requires specialized computer vision engineering.
you can rebuild
- Interactive PDP size guide overlay modal
- Form-based user size recommendation (height, weight, age, fit preference)
- Storefront analytics dashboard for sizing widget interaction rates
- CSV ingestion interface for brand garment measurement charts
- Dynamic fit advice callouts (e.g., 'Runs small, order one size up')
what you lose
- Smartphone camera video/photo 2D AI body scanning models
- GDPR-compliant biometric data pipeline that auto-deletes raw user images
- Cross-brand body measurement and actual garment return outcome models
- Automated garment spec parsing from pattern design files and CAD tech packs
- Integrated 3D body visualization models for end-users
