Segment prospecting for B2B sales: finds candidate companies in a given niche or hypothesis (e.g. 'medical tourism', 'online English schools', 'car rental services'), verifies each against two strict criteria (segment fit + your ICP signal) and saves a prioritized xlsx (priority signal × company scale). Use when the input is a segment description, NOT a specific company. Output feeds company-context. Skill body is in Russian. Triggers (EN): 'find 30 companies in niche X', 'list candidates in segment Y'. Triggers (RU): «накидай компаний в сфере X», «найди 30 компаний ниши Y», «список площадок в сегменте Z».
