Only equity rounds with a stage count; debt, grants and public companies' raises do not. Each month the eight countries with the most equity rounds get their 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)
