find out who is building claude for

claude for

A directory of companies that pitched themselves as “claude for ___”.

Built a “X for Y” startup? Add yours — DM @sidisgame ↗

How this works. Entries are gathered from public sources — Y Combinator's company directory, Hacker News launches, GitHub, and reader submissions — and matched against the pattern “[well-known product] for [vertical].” Nothing is paraphrased or invented: the highlighted text is verbatim from the company, or it doesn't get listed. Click any card for the source.

The formula predates AI by a decade: Uber for X (2011) begat Shopify for X, Stripe for X, Copilot for X, Cursor for X. Claude Code for X showed up in Winter 2026 — and became the most-used version of all.

Get listed. Building something that pitches itself as “X for Y”? DM @sidisgame on X and I'll add it.
