- What is the latest Quantum Energy Partners fund?
- Quantum Energy Partners IX, LP, which first filed a Form D on Nov 24, 2025. Its own page carries the filed terms, the people named on the form and every filing on EDGAR.
- Who is the adviser to the Quantum Energy Partners 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 Quantum Energy Partners 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.
