The original source is here [1] at Ben Jones’s site (he’s a co-author). The HBR article is naturally a popular summary, but the underlying research seems to cover everything people are curious about in the threads so far (distribution of age, what was the criteria for high-growth, etc.). Like most NBER articles, it’s quite long, but you can skip to the end for the figures and get a lot out of it. Figure 1 is the main thing being reported, but I found Figure 4B to be the most important: founders over 30 have a higher likelihood of success.
