About ThirdLove

Founded 2013 · US

Heidi Zak and Dave Spector founded ThirdLove with a half-cup-size patent — moving the category from standard A/B/C/D-only sizing into 80+ sizes. The brand's fit-finder quiz captured millions of sizing data points and effectively crowd-sourced category R&D. Famous for the open-letter ad criticising Victoria's Secret in 2018 that became a viral marketing case study.

Notable for the llms.txt validator

ThirdLove's storefront is unusually data-rich because the fit-finder quiz drives most of the customer journey. The Schema + apps reflect that quiz-driven conversion architecture.

What this AI-search readiness signals

A C-grade llms.txt means the file exists but has structural problems — usually unparseable markdown, missing H1, or links that don't lead anywhere. These are common when a file gets hand-written without checking against the spec. Each finding ships with a copy-paste-ready markdown snippet on the live tool.

Cross-check with the Schema Audit — high-grade structured data + a clean llms.txt are the two pillars of AI-search visibility. Brands that win one tend to win the other.
