AltStreet Analysis
·Generated from EDGAR primary sources
Hack Fund IV-B Feeder LP is a Cayman Islands-domiciled feeder fund structured as a pooled investment vehicle, filed as an amended Form D by Hack Fund IV GP LLC with promoter Alexander Pack. The filing reports $58.9M raised from 20 investors under Rule 506(b) and Section 3(c) exemptions; minimum investment and first sale date are not disclosed on the filing.
This entity fits the typical venture/private fund feeder structure within alternative investments, relying on the common 506(b)/3(c) exemption pairing used by pooled investment vehicles to avoid both general solicitation restrictions and Investment Company Act registration. The undisclosed minimum investment and offshore (Cayman) domicile are consistent with institutional feeder structures that route non-U.S. or tax-sensitive capital into a U.S. fund complex, rather than retail-oriented offerings.

Questions About Hack Fund IV-B Feeder LP
Each answer is built from the values on the SEC filing and the AltStreet ledger, not from the issuer's marketing.
What is Hack Fund IV-B Feeder LP?
Hack Fund IV-B Feeder LP is a Cayman Islands limited partnership that filed a Form D with the SEC on November 3, 2025 as a private equity fund. The filing claims Rule 506(b), Section 3(c), Section 3(c)(7) for an offering of equity and pooled investment fund interests.
Is Hack Fund IV-B Feeder LP legit?
AltStreet does not rate legitimacy; it reports the public record. Hack Fund IV-B Feeder LP filed a Form D with the SEC on November 3, 2025 claiming Rule 506(b), Section 3(c), Section 3(c)(7). A Form D is a notice of an exempt offering, not a review or approval of it. No sales had been reported as of that notice. AltStreet's enforcement record (SEC, FINRA and state actions) shows no action naming the issuer as of today. Before investing, confirm the filing on EDGAR, check the seller's registration on FINRA BrokerCheck, and read the offering documents, which a Form D does not include.
Is Hack Fund IV-B Feeder LP registered with or approved by the SEC?
No. A Form D is a notice that an issuer is selling securities under an exemption from registration, and the SEC does not review, approve, or pass on the merits of the offering. The filing shows that Hack Fund IV-B Feeder LP claimed Rule 506(b), Section 3(c), Section 3(c)(7) and disclosed the items the form requires, such as the amount sold, the minimum investment, related persons, and anyone paid to sell the securities. It does not verify the issuer's claims or its business.
How much has Hack Fund IV-B Feeder LP raised?
Hack Fund IV-B Feeder LP reported that the first sale had not yet occurred as of the Form D filed November 3, 2025, so no amount sold or investor count is on file. The total offering amount is listed as indefinite.
Who can invest in Hack Fund IV-B Feeder LP?
The offering relies on Rule 506(b), which permits sales to accredited investors and to no more than 35 non-accredited investors who meet a sophistication standard, and prohibits general solicitation. Because the fund also relies on Section 3(c)(7), each investor must be a qualified purchaser, generally an individual with at least $5 million in investments. The filing reports no non-accredited investors. The filing lists the minimum investment as $0, meaning no minimum was stated.
What is the minimum investment in Hack Fund IV-B Feeder LP?
The Form D lists the minimum investment as $0, which means the issuer did not state a minimum on the form. The offering documents, not the Form D, set the actual subscription terms.
Who is selling Hack Fund IV-B Feeder LP and how are they paid?
The Form D names no recipient of sales compensation, which usually means the issuer or its affiliates are placing the securities directly. Sales commissions are reported as $0 and finders' fees as $0. Form D allows these to be estimates.
Who is behind Hack Fund IV-B Feeder LP?
The Form D lists 2 related persons: HACK FUND IV GP LLC, promoter (GENERAL PARTNER OF THE ISSUER); ALEXANDER PACK, promoter (MANAGER OF THE GENERAL PARTNER OF THE ISSUER). Form D Item 3 requires executive officers, directors, and promoters of the issuer to be listed.

How long is the Hack Fund IV-B Feeder LP offering open?
