 do not seem to have grown more quickly since the advent of generative AI. One explanation for this is that AI tools didn't become valuable until the last ~1 year. If this is true, we should expect to see different results next year.

On Sept 1 2026, I will rerun exactly the methodology from that blog post (unless someone points out a bug, in which case I will disclose it here). Of the companies that I find most grew their valuation in the year after having done YC, how many of them will have done a YC batch in 2024 or later?
