AltStreet Analysis
·Generated from EDGAR primary sources
CABF Lumen Feeder Co-Invest, L.P. is a Cayman Islands-domiciled pooled investment fund structured as a feeder/co-investment vehicle, filed as an original Form D on 2026-11-10 under Rule 506(c) and Section 3(c) exemptions. The filing is pre-open, with total amount sold, investor count, and minimum investment not disclosed. Related parties include CABI GP, L.L.C. as promoter and David Lobe and Christina von Poelnitz as executive officers; no parent platform or sibling entities are currently matched in the database.
This filing fits the common pattern for private feeder/co-investment vehicles in the alternative investment space: a Cayman Islands fund pairing a 506(c) general solicitation exemption with a 3(c) Investment Company Act exclusion, typical of institutional or fund-of-funds structures that solicit accredited/qualified investors while remaining unregistered. With no disclosed raise amount, investor count, or minimum investment, it cannot yet be benchmarked against typical check sizes in this category.
Data Flags
State of IncorporationEntity is domiciled in the Cayman Islands, indicating a cross-border/offshore fund structure filing a U.S. Form D, likely to accommodate non-U.S. or tax-sensitive investors feeding into a related domestic vehicle.
ExemptionFiling claims both 506(c) and 3(c) exemptions simultaneously, a structure common to institutional co-invest/feeder funds pairing a securities-offering exemption with an investment-company exclusion.
First Sale Date / Total Amount SoldNo first sale date or total amount sold is disclosed on this original filing; raise size cannot be determined, so pre-open status cannot be benchmarked against the $100M institutional threshold.
