Every sentence is a value as filed on SEC Form D

Spartan Fund I, a Series of SecondMarket Growth, LLC is a Delaware limited liability company organized in 2026 that filed a Form D with the SEC on October 9, 2026, describing itself as a other investment fund. The offering claims Rule 506(b), Section 3(c), Section 3(c)(1) and covers pooled investment fund interests. Spartan Fund I, a Series of SecondMarket Growth, LLC reported $1,236,794 sold from 16 investors of a $1,236,794 total offering as of the Form D filed October 9, 2026. The filing states that the figure is combined across related vehicles, so it is not this entity's figure alone. 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)(1), it may have no more than 100 beneficial owners. The filing reports no non-accredited investors. The minimum investment accepted from an outside investor is $100,000. 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. The issuer reports $98,944 of gross proceeds used or proposed to be used for payments to related persons. The issuer's address of record is 3 East 28 Street, 7th Floor, New York, NY 10016.

Grouped from Form D issuer names (generation, sleeve, jurisdiction and legal-form tokens removed); a name-only match, so abbreviated or renamed vehicles can be missed. Sold and investor figures are each vehicle's latest Form D; sleeves that report the same figure share one family-wide total and are counted once. Performance lines are what a public pension plan reports for its own interest in that fund, net, on the plan's cash flows and valuation date; they are not the general partner's figures.
