Frequently asked questions
- How is this AI founder directory built?
- Records are assembled from public company registrations, funding announcements, conference and demo-day rosters, company websites, and public professional profiles, then cross-checked against each other. A record only enters the directory when at least two independent sources agree on the person, the company, and the role. Contact paths are validated separately before a profile is marked reachable.
- How often is it updated?
- Every profile is re-verified on a rolling 30-day cycle. Founders who leave, companies that shut down, and contact details that stop resolving are removed rather than left in place. The last full verification pass for this directory ran on 4 August 2026.
- Why are the email addresses masked?
- Publishing verified contact details on a public page turns the directory into a scraping target and offers no protection to the people listed. Masked previews show that a verified path exists without exposing it. Full contact details are available to signed-in users, subject to Articuler's acceptable-use terms.
- What counts as an "AI founder in San Francisco"?
- A founder or co-founder of a company whose primary product is AI-native, where either the company is headquartered in San Francisco or the founder is personally based there. Founders at large non-AI companies running an internal AI team are excluded, as are advisors and early employees without founder equity.
- Can I filter the list?
- Yes — signed-in users can filter by funding stage, headcount band, AI sub-sector, founder role, neighborhood, and how recently the profile was verified, then export the filtered set or push it straight into an outreach sequence.
- How do I get a profile removed?
- Anyone listed can request removal or correction, and requests are actioned within five business days across the live directory and all downstream exports.
