Scope, evidence and limits
Description: London AI company set up by David Silver; incorporated in the UK on 19 November 2025 as INEFFABLE INTELLIGENCE LTD.
The records are grouped automatically. No human inspection of the selected claims, source paths or framing is recorded for this dossier. Each source passage shows how it was checked.
The dossier is computed from existing records. It is not a continuous history of the institution, and a missing record does not mean that an event or relationship did not happen. The chronology uses the dates of events and reports, not the date the public could first have known of them. Later sources can describe earlier events.

Qualification and date notes
Silver’s wording is “set up”; the note names no co-founders, and the record does not establish a complete founder roster or a founding date. The Cooley release describes the company as founded by David Silver.
The note is dated 15 January 2026 but gives no founding date; the company was incorporated on 19 November 2025 (recorded separately).
