Fireround / Investors that led the most funding rounds lately

Ranks investors by the announced or reported rounds they led in the last 7, 30 or 90 days, optionally within one sector or set of stages. Each has rank, rounds_led, lead_share_usd_millions (each led round's amount split evenly between its leads) and its newest led rounds (company, stage, amount, announced_on). Fireround's own example, investors that led the most AI rounds in the past 30 days: {"window":"30d","sector":"ai"}. Every input is optional. Records are extracted automatically by Fireround (an open funding feed run by Firecrawl) from news articles, company announcements and filings, so some are wrong: cite the source links each record carries and check certainty before you state a round as fact.
