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.

GAV is the gross asset value the adviser reported on Form ADV for the vehicle, never the fund’s committed size and never dry powder. Form D sold is the amount sold as of the latest filing, never a final close.

Investments on record
0 edges, 0 companies, 0 partner-attributed
No investment on record yet. Edges arrive from the firm’s portfolio page, financing announcements, and Form D board seats.
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.
