56 connected entities1 observed round
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.

›How strength and recency are read
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?

What these amounts mean“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.Acquired, Public, Exited and Active are what the firm’s own portfolio card says, read on the date shown when you hover the chip; they are not deal dates. A company with no chip is one whose card states no outcome: DFX does not assume it is active.| Company | Round | Role | Partner | Round size | This investor | Date | Source |

What these amounts and dates areEach commitment is counted once across the pension tape and the allocator graph. A commitment date prints only when the source printed one; otherwise the row carries the report date. A foundation’s 990-PF line is a holding at fair value, never a commitment. Rows without a fund on the venture graph are commitments to this manager.Relationships across DFX
