What matters now
- 1 companyportfolio raising
One portfolio company has new financing on record in 6 months without this firm named on the round; the latest on 29 May 2026 ($55.8M sold on Form D).
A portfolio company raising again is a follow-on decision for the firm and a co-investment opening for others.
Relationship network
52 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.
- Sponsor
- Company
- Fund or vehicle
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.
