People in AI and technology · compiled from public sources
Dossiers
Dossiers are profiles of people who shape AI and other technology: who they are, the roles and board seats they have held, who has put money into the companies around them, and a dated list of what those companies and the people themselves have announced.
Everything here is a public professional fact, compiled by hand from public sources: company pages, filings and announcements. Where a news outlet is ever used it is labelled “as reported by”. Each fact links to its sources, and each profile’s source list shows the day every source was read. Where a source gives no date or detail, the page says so instead of filling it in, and nothing about private life is recorded.
Each source was read on the day shown in the source list. A profile is due for a fresh read of its sources after 180 days.
