What this page covers
Presspool records the lead investors of each round, as the company's announcement or the confirming outlets name them, and the other investors the round's entry names. This page lists the rounds this investor led on Presspool's record: every weekly AI startup funding roster, and the latest round of each company on a niche map. A round it joined without leading is listed when the round's entry names it, matched only to firms the record names as some round's lead. It is not the investor's full portfolio: rounds its sources did not name it in are not listed.
