Look a company up in HeadStart's Company directory by name — typos, prefixes and known aliases are matched — and list every candidate with its key, its Boards (the ATS job boards it is read from), its tech openings now and how it matched. Nothing is picked: one employer can be several entries (one per ATS, or a regional arm), and a typo or prefix match is a guess to confirm with the user. Of entries with the same name only the largest is listed, as in the site's picker. A key, such as 'greenhouse:stripe', names one entry exactly: pass it as company to company_profile or search_jobs, or in read_trends' companies. A Board key given as name is looked up exactly.
