These are activity signals, not fund-return metrics. Round capital is the full disclosed financing amount, not this fund's check size. “Recorded solo” means only one investor is present in the source data and is a lead signal, not verified lead status; syndicated rounds are a co-investor or follower signal. IRR, TVPI, DPI, ownership, exits, and market beta cannot be calculated from the available records.
