Unlock in the terminal (Investor)Questions about the Lightspeed M funds
- How many Lightspeed M funds are there?
- The SEC Form D record shows 2 vehicles in 2 numbered generations, the earliest filed Jun 27, 2024 and the latest filing on Apr 22, 2026. By generation: Fund II (Lightspeed M2, L.P., first filed Apr 22, 2026); Fund I (Lightspeed M1-B, LLC, first filed Jun 27, 2024).
- What is the latest Lightspeed M fund?
- Lightspeed M2, L.P., which first filed a Form D on Apr 22, 2026. Its own page carries the filed terms, the people named on the form and every filing on EDGAR.
- Who is the adviser to the Lightspeed M funds?
- AltStreet has not joined a Form ADV adviser to this family's Form D filings. The adviser, if any, appears in each fund's offering documents, which a Form D does not include.
- How much have the Lightspeed M funds raised?
- Each vehicle reports an amount sold and an investor count on its latest Form D or amendment, and those figures are on each vehicle's entity page. The totals by generation are in the AltStreet Terminal (Investor), where master and parallel sleeves that report one family-wide figure are counted once.
- How does AltStreet group these funds into a family?
- By name: the base name minus the fund number, sleeve letters, jurisdiction and legal form, read from each issuer's Form D (lib/edgar/fundFamilies.ts). 'Fund IV' is generation 4; a vehicle whose name carries no number is listed as unnumbered. It is a name-based grouping, not a statement of common control; the filings on each entity page show the related persons as filed.
