Individual skill
perfect-company-list
Build a near-complete company list for any ICP by learning how your real customers label themselves, pulling every industry and keyword they use, judging every single row with a cheap AI model (Jev or gpt-5-nano), and running a Claygent lookalike loop until it runs dry. The method from the SCULPT 2026 talk "Build the perfect company list". Use when a database filter feels too narrow or too noisy, when someone says "find every company like our customers", "our TAM looks too small", or "why is this list full of junk".

# Perfect company list
Database filters fail in two directions at once.
- **They miss real fits.** Industry labels are self-reported, or guessed: many LinkedIn company
pages carry the banner "This listing was automatically created by LinkedIn", which means nobody
at the company picked the label. We found an FDIC bank listed as *Construction*, an SEC-registered
wealth manager listed as *Semiconductor Manufacturing*, and a New Jersey school district listed
as *Retail Luxury Goods and Jewelry*.
- **They pull in junk.** A plain `Banking` + `United States` filter returned 16,895 companies. About
10,500 of them were not banks: 3,679 mortgage companies and lenders, 2,414 credit unions, 2,210
dead sites or unrelated businesses (a Toyota dealer, a pawn and gun shop, a youth soccer club),
839 vendors that sell to banks, and the Federal Reserve Bank of St. Louis.
