In a typical year, a double-digit number of tech companies IPO (there was a big jump in 2021 and then a crash in 2022/2023, with 2024 seemingly back in the double-digit range). https://www.visualcapitalist.com/charted-four-decades-of-u-s...
Let's be really clear, though: there's "getting good value for options" and then there's "getting some value for options." It is straightforwardly true that in general big public companies have better comp than pre-IPO companies: the guaranteed value of equity in your Metas or Googles or even lower-tier public companies is generally higher than the expected value of pre-IPO equity, even if you are relatively risk-insensitive.
That is importantly different from "the value of pre-IPO equity is zero," or "it is a one-in-a-million event to get value from pre-IPO equity."
