Industry Mapping with Claude — Gathering 259 Companies in One Day and Correcting Incorrect Figures Using Public Disclosures

This is the actual process of having Claude divide the beauty-and-biotech sector into eight country-specific segments and assign one to each, creating an industry map of 259 companies in a single day. I then checked and corrected the inaccurate figures mixed into that map, one by one, against the original filings on Korea’s DART, the U.S. SEC EDGAR, Hong Kong’s HKEXnews, and the U.K.’s Companies House—and I’ll also provide the prompt for applying the same process to my own industry (figures as of October 14, 2026).
