About this data

We list facts from a16z speedrun's public directory: names, websites, locations, team sizes, and founders. Company descriptions stay on the source; each company links to its original page.

While a cohort is still filling, we check its roster every day, and each page shows the date of the last check. Companies that drop off the directory drop off the roster here too.
