What this filing shows
·Every sentence is a value as filed on SEC Form D
Spectrum Equity XI-C, L.P. is a Delaware limited partnership organized in 2026 that filed a Form D with the SEC on October 9, 2026, describing itself as a private equity fund. The offering claims Rule 506(b), Section 3(c), Section 3(c)(1) and covers pooled investment fund interests. Spectrum Equity XI-C, L.P. reported $2,375,000,000 sold from 52 investors of a $2,375,000,000 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 filing lists the minimum investment as $0, meaning no minimum was stated. 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's address of record is One International Place, 35th Floor, Boston, MA 02110.

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.

Questions About Spectrum Equity XI-C, L.P.
Each answer is built from the values on the SEC filing and the AltStreet ledger, not from the issuer's marketing.
What is Spectrum Equity XI-C, L.P.?
Spectrum Equity XI-C, L.P. is a Delaware limited partnership organized in 2026 that filed a Form D with the SEC on October 9, 2026 as a private equity fund. The filing claims Rule 506(b), Section 3(c), Section 3(c)(1) for an offering of pooled investment fund interests.
Is Spectrum Equity XI-C, L.P. legit?
AltStreet does not rate legitimacy; it reports the public record. Spectrum Equity XI-C, L.P. filed a Form D with the SEC on October 9, 2026 claiming Rule 506(b), Section 3(c), Section 3(c)(1). A Form D is a notice of an exempt offering, not a review or approval of it. The newest notice reports $2,375,000,000 sold to 52 investors. 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 Spectrum Equity XI-C, L.P. 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 Spectrum Equity XI-C, L.P. claimed Rule 506(b), Section 3(c), Section 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.
How much has Spectrum Equity XI-C, L.P. raised?
Spectrum Equity XI-C, L.P. reported $2,375,000,000 sold from 52 investors of a $2,375,000,000 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.
Who can invest in Spectrum Equity XI-C, L.P.?
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.

The filing lists the minimum investment as $0, meaning no minimum was stated.
What is the minimum investment in Spectrum Equity XI-C, L.P.?
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.
