Firms, funds, partners, companies and rounds from sworn filings, firm sites and announcements, kept as a graph with a date and a source on every edge. Facts, inferences and estimates are labelled as such. A fund target is never a close, GAV is never dry powder, and a round size is never an investor’s check.

Each row is the LP’s own number: its cash flows and its valuation policy as of its reporting date, not the fund’s. Net IRR is printed only when the LP prints one. The vintage is the LP’s definition (CalPERS: year of its first cash flow; WSIB: year of its initial investment).
