made** It is written from the rounds we read that month in named articles and filings, by the sectors we file each company under; a company can sit in more than one, so sector roundups overlap. Only equity rounds with a stage count; debt, grants and public companies' raises do not. Each sector with 10 or more equity rounds in a month gets its own roundup. We read more sources every month, so compare medians, not totals. [How we read rounds](https://millionrounds.com/methodology) · [Report a mistake](https://millionrounds.com/corrections)
