DFX Intelligence
Venture Capital Intelligence
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.

“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
1 relationships from shared deals, counted for the whole firm
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.
