OneSearch is built for the ten minutes before a conversation — the gap between asking "who is this?" and walking into the room. Type a name, confirm which person you mean, and OneSearch returns a single sourced brief assembled from indexed public web pages: company sites, talks, writing, developer profiles, press and social. It is explicitly not a people database you browse; it is a briefing engine for a specific person you already have a reason to research.
The product is opinionated about what most people-search tools skip. Disambiguation comes first, because common names collide and a brief generated against a guessed match is worse than no brief at all. Every material line is linked back to the page it came from, and when the public web is quiet, the page stays thin rather than filling gaps with confident fiction. Follow-up questions are answered against the same brief and the same sources, so the thread stays attached to the person you already confirmed.
OneSearch is used by recruiters screening a passive candidate before first outreach, founders prepping for a meeting, sellers doing discovery research and researchers assembling context. Lookups do not notify the subject and history stays saved on your account. Crucially, the tool is designed for public-web research only: the site states plainly that it is not a background check, is not a consumer reporting agency and is not FCRA-compliant, and it should not be used for regulated screening decisions. Pricing runs on weekly, monthly, quarterly and yearly intervals with unlimited lookups for normal professional use.
