The Index
Every published Anthropic customer story. One row per story, 256 rows, alphabetical. Each row links to the official page, which is always the authority.
How to search this page
- Wiki search. The search box at the top of this site indexes every row.
- Browser find. The whole index is one page, so Ctrl+F / Cmd+F reaches everything: a company name, a vertical like "legal", a surface like "Claude Code", or a number.
- For agents. This wiki publishes llms-full.txt, which carries this entire table in plain text.
- The source wins. Every company name links to its official claude.com/customers page. If a number matters to a decision, click through and read the original.
Column notes: Vertical is normalized to a short controlled vocabulary. Surface compresses the Anthropic products the story names. Standout number is one metric quoted from the story, shortened but never reworded; "qualitative" means the story publishes no usable number. Seven stories carry self-contradicting figures; their cells avoid the contested numbers or point to Strength of evidence. YC marks companies confirmed in the Y Combinator directory (21 of 256 rows).
A few companies appear twice because Anthropic published two distinct stories about them; each row is one story.
