Why Tellar vs. Competitors

The B2B Problem

Most sizing technology companies (True Fit, Bold Metrics, Fit Analytics) operate as B2B platforms:

They charge retailers £5,000-50,000 per month for integration
Only work on partner retailer websites
Limited to brands that pay for the service
Consumers get fragmented access across different sites
Potential conflicts of interest between accuracy and business relationships

The Tellar Advantage

Our D2C model eliminates every limitation:

Universal Coverage: 1,500+ brands regardless of partnership status
Zero Cost: Completely free for all consumers, forever
Single Profile: One measurement set works everywhere
Complete Independence: Unbiased recommendations driven purely by data
Cross-Brand Intelligence: Compare sizes across your entire wardrobe
Global Access: Available worldwide, not limited by retail partnerships

Tellar is the only global sizing organization with expansive brand coverage, proprietary databases, and completely free consumer access. We're not just competing with B2B platforms—we're creating an entirely new category.
