- Small, relatively young company.
- Absolutely gargantuan amounts of revenue
You can't run a company this way unless you have a very large money firehose.
The last time this happened was early-Facebook. I don't think there has been a single company since then that fit the description - which IMO is fine, the celestial alignment of factors is pretty rare.
Companies nowadays have kind of the opposite problem: lots of hiring, but not enough revenue to show for it. Some tried to build a similar culture on VC funding but imploded once the cash ran out. You really need an intensely profitable product to make this formula work.
