I always hear this line of thinking, but there aren’t ever supporting examples presented. Stripe reminds me of Cloudflare. Cloudflare is over 5x what it was at IPO (as of 6/14/21). Maybe what you describe is the case “on average” for most IPOs, but it seems to not be the case for extraordinary companies like Cloudflare (and maybe Stripe). Obviously just an n of 1 but I’m sure others could chime in with similar examples.
