AltStreet Analysis
·Generated from EDGAR primary sources
NB Secondary Opportunities Fund VI LP is a Delaware pooled investment fund (secondaries vehicle) managed under NB Alternative Advisers LLC, filed as an amended Form D on 2026-11-02 under Rule 506(b) alongside a Section 3(c) Investment Company Act exemption. The filing reports $1,893.4M raised from 308 investors with a stated $500K minimum investment; no first sale date is disclosed, which is typical for large institutional amendment filings of this size.
This is a large-scale institutional private fund offering in the alternative investment secondaries space, pairing a standard 506(b)/3(c) exemption structure common to private equity secondary funds. The $500K minimum and ~$6.1M average check size across 308 investors are consistent with an institutional-and-high-net-worth LP base rather than a retail-oriented vehicle.

Questions About NB Secondary Opportunities Fund VI LP
Each answer is built from the values on the SEC filing and the AltStreet ledger, not from the issuer's marketing.
What is NB Secondary Opportunities Fund VI LP?
NB Secondary Opportunities Fund VI LP is a Delaware limited partnership that filed a Form D with the SEC on October 30, 2025 as a private equity fund. The filing claims Rule 506(b), Section 3(c), Section 3(c)(7) for an offering of pooled investment fund interests.
Is NB Secondary Opportunities Fund VI LP legit?
AltStreet does not rate legitimacy; it reports the public record. NB Secondary Opportunities Fund VI LP filed a Form D with the SEC on October 30, 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 NB Secondary Opportunities Fund VI 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 NB Secondary Opportunities Fund VI 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 NB Secondary Opportunities Fund VI LP raised?
NB Secondary Opportunities Fund VI LP reported that the first sale had not yet occurred as of the Form D filed October 30, 2025, so no amount sold or investor count is on file. The total offering amount is listed as indefinite.
Who can invest in NB Secondary Opportunities Fund VI 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 NB Secondary Opportunities Fund VI 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 NB Secondary Opportunities Fund VI 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 NB Secondary Opportunities Fund VI LP?
The Form D lists 15 related persons: NB Secondary Opportunities Associates VI LP, promoter ("General Partner of the Issuer (the ""GP"")"); NB Secondary Opportunities Associates VI GP LLC, promoter (General Partner of the GP); NB Alternative Advisers LLC, promoter (Investment Adviser); Brian Talbot, executive officer (Managing Director of the GP of the Issuer's GP); Ethan Falkove, executive officer (Managing Director of the GP of the Issuer's GP); Tristram Perkins, executive officer (Managing Director of the GP of the Issuer's GP); Peter Bock, executive officer (Managing Director of the GP of the Issuer's GP); Benjamin Perl, executive officer (Managing Director of the GP of the Issuer's GP), and 7 more. Form D Item 3 requires executive officers, directors, and promoters of the issuer to be listed.
