Brian Chesky, Co-founder and Chief Executive Officer. CEO, so Chesky sees company-wide numbers first-hand; Chesky also has an interest in presenting Airbnb's AI progress favorably to investors.
Checked against the source by a first reader, then confirmed independently by a second reader who fetched the source without seeing the first reader's notes (Independent review agent (Claude Sonnet), blind second pass from passage text and citation only, no repository access, 2026-10-31).
The sentence matches exactly in the Q&A, in the middle of a first-person answer about a custom model ('what we've done is we built a custom model...'). I did not separately verify the speaker label on that turn, but the first-person Airbnb context fits Chesky.
