Staff list a company once its homepage loads and one to three sources back it up. Map pins use a sourced city or region — near that place or at the region centroid. Unknown location stays list-only. Founders, exit, and jobs stay omitted unless sourced. Founder photos stay omitted unless a sourced URL is listed — we never invent a face. We do not invent people, a street address, or size, price, or growth figures.
