Sources & location evidence
Open research desk ↗Profile source review: 2026-11-04. Current AI product, canonical company identity, and supported NYC operations. Funding stage and amounts were not rechecked. Strict NYC inclusion reviewed against current company product/careers sources. Office occupancy and street address require separate evidence; a mailing address is not a pin.
Flatiron, Manhattan · verified office
Street address not public. Public founder recruiting post supplies first-party physical office and neighborhood evidence. Exact posting date is not displayed in the reviewed public page. This improves the prior third-party neighborhood mirror while preserving the separate mailing-only record; 169 Madison Avenue, Suite 38212 must not become a street office pin. No exact office address verified.

No Williamsburg evidence found.
