Relationship network

152 connected entities

From financing rounds and every investor named in them, Form ADV and Form D filings, the firm's funds and team, and disclosed LP commitments in the venture capital graph. A round's amount is the size of the round, not money that moved between two investors.

Some relationships on this record are counted rather than named here. They open with the full profile.

Click any name or line for the rounds and sources behind it. Line weight is rounds together; dashed lines are inferred.

Reading the network
  • Fund or vehicle
  • Person

Co-investors are read from the rounds: three or more shared rounds is a strong observed relationship, two a repeat co-investor, one a single round. Funds and people are structural. Nothing is scored that a reader cannot check.

How am I connected?

Name your firm, a company or a person, and DFX finds the published routes to Proof: a shared portfolio company or board, a prior employer, a co-investor, a shared LP or service provider. Every step is a filed or published record with its source; none is a guess about who knows whom.

  • score 34confidence 60%
    Why: sector fit; geography fit; activity
    Watch: no observed deals

Scored by DFX match engines from the record's observed portfolio, stage, geography and recent activity. A fit is a reason to look, not a mandate; the blockers say what the model could not confirm. Names and the evidence sentences show with the names on this page.

Record history

1 dated event on the change ledger, latest first
  • Adviser's first ADV filing

The ledger records every merge, rename and reclassification this record went through and the dated filings observed on it, so the identity on this page can be traced to the records it was built from. The ledger's own sentences name other records, so they show with the names.
