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.
