AltStreet Analysis
·Generated from EDGAR primary sources
Onex Partners VI B LP is a Delaware-organized pooled investment fund vehicle filed under Form D by Onex Partners, claiming Rule 506(b) and Section 3(c)(1) exemptions for a private offering of equity interests. The filing is pre-open with no disclosed total amount sold, investor count, or first sale date, consistent with an original (non-amended) filing for a fund still in formation. Related persons include executive officers tied to the Onex Partners VI B GP structure and Amir Motamedi as director, with Matthew Murphy listed as an executive officer/promoter.
This filing fits the standard profile of an institutional private equity fund vehicle within the alternative_investment category, combining a Rule 506(b) Reg D exemption with a Section 3(c)(1) Investment Company Act exclusion — a common structure for closed-end PE funds limited to accredited investors. No minimum investment is disclosed on the filing, which is typical since that figure is generally governed by the fund's limited partnership agreement rather than the public Form D.

Questions About Onex Partners VI B LP
Each answer is built from the values on the SEC filing and the AltStreet ledger, not from the issuer's marketing.

The filing shows that Onex Partners VI B LP claimed 506(b), 3(c)(1) 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.
