Airbnb cut marketing spend by $446M and came out bigger

By 2021 revenue was 25% above 2019 on a marketing budget still 27% below it. The filings show what that spending was really buying.

The archive

Every case, filterable by category and format

Watch: breakdowns worth your time

Curated from other channels. We do not produce these.

Nothing curated yet. This row will hold videos from other people's channels — each one credited to the channel that made it, opened in a player that only loads when you click it.

We are not filling it with placeholder thumbnails in the meantime.

Market Pulse

Short news, with the part that matters

The daily news desk has not started yet. When it does, this is where two or three short items a day will land — each one a headline, a single sentence on why it matters, and a source.

Until then, everything we have published is in the archive.

Community Pulse

How readers rate what we publish

No votes yet. Every article carries a four-way rating — Game Changer, Hot Deal, Overrated, Flop — and this panel shows the running total across the site once readers start using it.

ROI Hall of Fame

Two boards, because a percentage and a dollar are not the same achievement

Five published cases is not a leaderboard. We would rather show nothing than rank a field of five and call it a ranking — the same rule the Lab uses when it refuses to show a confidence level below three matching cases.

The two boards — highest ROI percentage and largest absolute impact — open once there are enough comparable cases to make the order mean something.
