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.

“This investor” is the amount disclosed for this investor alone; it is unknown unless a source said it. The round size is the whole round.
Co-investors
0 relationships from shared deals, counted for the whole firm
No co-investor relationship yet: these are derived only from rounds and portfolio listings the graph has seen both investors on.
Limited partners
0 disclosed
No LP commitment on record. An LP edge needs a public disclosure with a quote: a pension report (see Limited partners for the plans read), a fund announcement naming the LP, or a Form ADV owner. The fund page carries the LP’s reported performance.
