Fundraising evidenceWhat counts as raisingA Form D offering is permission to sell, not a fund in market; an amount sold is never a close; an evergreen offering amended every year is not a raise.

Limited partners and their reported performanceWhose numbers these areEach row is the LP’s own number: its cash flows and its valuation policy as of its reporting date, not the fund’s. Net IRR is printed only when the LP prints one. The vintage is the LP’s definition (CalPERS: year of its first cash flow; WSIB: year of its initial investment).
0 public LP reports
No public LP has reported this vehicle. The LP tape is read from public pension disclosures (see Limited partners); a fund appears here only when an LP’s report names it.
Known LPs and allocatorsWhat these amounts and dates areA commitment date prints only when the source printed one; otherwise the row carries the date of the report that listed it. A foundation’s 990-PF line is a holding at fair value on its return, never a commitment.
0 relationships, public pensions and the allocator graph, each counted once
No allocator names this vehicle in a public disclosure DFX holds: pension reports, foundation 990-PF returns or endowment disclosures.
Investments attributed to this vehicle
0
No investment attributed to this vehicle. The firm’s investments sit on the firm; a fund gets one only when a source names the vehicle.
