I don't know why comments pointing out this simple fact are getting downvoted.
The oversimplified view that has been drilled into startup discussions for years has been that IPO is the singular goal for every startup and they need to get there as fast as possible, but that hasn't been true for a long while. There are high profile examples like Stripe with no intent to go public any time soon. Some public companies are even gradually doing share buybacks partially to remove their public exposure.
Being a public company kind of sucks in many ways. I'll admit my sample size is small, but every post-IPO CEO I've known has expressed some regrets about going public. It was a fascinating revelation to me after being raised on the idea that IPO is the ultimate victory goal of every startup.
