Relationship network

15 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
  • Sponsor
  • Company
  • 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.

Darker lines were active in the last 24 months or are current; lighter lines are older or undated.

How am I connected?

Name your firm, a company or a person, and DFX finds the published routes to JAM Fund, LLC: 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.

    Why this person: Named with investment responsibility

Ranked by the role the firm or its filing states, a route on file and deals led. Every reason is read from the record, never inferred. Routes are published by the person or the firm (their bio, the team page or a filing) and are revealed on a plan; data bought from a provider is never shown, and a route printed at a firm the person has since left is held back.

Known LPs and allocators
0 relationships across the firm's funds, from public pensions and the allocator graph
