What matters now

  1. 1 vehicle
    on Form D, 18 months

    $40.4M reported sold so far.

    A Form D is filed when a vehicle takes its first money, so these are open to LPs now.

  2. 6 companies
    new in 12 months

    6 new companies in the last 12 months.

    A firm writing cheques this quarter is one a founder can pitch now.

  3. 8 companies
    portfolio raising

    8 portfolio companies have new financing on record in 6 months without this firm named on the round; the latest on 25 Aug 2026 ($14.4M sold on Form D).

    A portfolio company raising again is a follow-on decision for the firm and a co-investment opening for others.

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

›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?

Name your firm, a company or a person, and DFX finds the published routes to The Engine Funds: 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.
