AltStreet Analysis
·Generated from EDGAR primary sources
ASF IX Sidecar A, L.P. is a Delaware-organized pooled investment fund vehicle filed under Form D exemptions 506(b) and 3(c), with ASF IX Sidecar GP, LLC and AlpInvest Secondaries IX Lux GP S.à r.l. listed as promoters, indicating this is a sidecar co-investment vehicle tied to an AlpInvest-sponsored secondaries fund program. The filing is pre-open, with total amount sold, investor count, first sale date, and minimum investment all undisclosed, consistent with an initial Form D filing ahead of fundraising activity. No parent platform or related entity family has been matched in AltStreet's database at this time.
This vehicle fits the private equity secondaries co-investment segment of the alternative investment landscape, structured as a Rule 506(b) private placement excluded from investment company registration under Section 3(c) of the Investment Company Act — a standard combination for institutional private funds. No minimum investment is stated on the filing, which is typical for institutional vehicles where investor terms are governed by a private LPA rather than the public Form D.
