Who would invest
How comparable investors are foundComparable investors backed two or more of the companies this company’s own investors also back. Broader fit co-invested two or more times with them and dated a new company in the last 12 months. Each reason is a fact on record: a shared company, a co-investment count, a dated deal, a stage or round size it has joined. A shared sector alone never puts a firm here. Nothing is a prediction that a firm will invest.Already invested

Ownership and outcomes
How these are wordedA company a buyout or growth firm lists on its own site is “listed in the portfolio of”, never “acquired by”. A date prints only when a deal record gives one; otherwise the row says when DFX first saw it.Listed on 1 firm portfolio page; none states an outcome (acquired, public, exited or active). DFX does not assume the company is active.

Credit relationships
How a loan is matchedA BDC reports its loans by borrower name. A position shows here only when the match passed a precision gate (a hand-labelled sample was 29 of 30 correct); the tier and confidence are printed on each row. Amounts are the lender’s reported position, never a round.People
