Generated from EDGAR primary sources

Mason Wells Buyout Fund VI, LP is a Delaware-organized pooled investment fund vehicle filed by Mason Wells Buyout Partners VI, LLC (with Jay Radtke as executive officer), reporting $833.3M raised from 68 investors at a stated minimum investment of $105K under Rule 506(b) and Section 3(c)(1) exemptions. No parent platform or sibling entities are currently matched in the database, suggesting this is either a standalone filing or the first entry from this sponsor group on record.

This filing fits the typical profile of a large private equity buyout fund within the alternative_investment category, combining a Rule 506(b) securities exemption with a Section 3(c)(1) Investment Company Act exemption — a common pairing for closed-end PE funds limited to fewer than 100 beneficial owners. The $105K stated minimum is low relative to the implied average check size (~$12.3M across 68 investors), which is typical for institutional buyout funds where the public minimum differs from actual negotiated commitments in the LPA.

Data Flags

First Sale Date / Total Amount SoldFiling reports $833.3M already sold to 68 investors but discloses no first sale date on an original (non-amendment) filing — this combination is unusual since a completed raise of this size typically has an identifiable first sale date.
ExemptionFiling claims both Rule 506(b) and Section 3(c)(1) exemptions simultaneously, a common structure for private equity funds combining securities and Investment Company Act exemptions.
Minimum InvestmentStated minimum of $105K is low relative to the implied average investor check size of roughly $12.3M, indicating the filed minimum likely does not reflect actual institutional commitment sizes.
