- How many AH Bio Fund funds are there?
- The SEC Form D record shows 8 vehicles in 4 numbered generations, the earliest filed Dec 20, 2017 and the latest filing on Dec 2, 2025. By generation: Fund V (2 vehicles, first filed Mar 20, 2025); Fund IV (2 vehicles, first filed Jan 21, 2022); Fund III (3 vehicles, first filed Feb 4, 2020); Fund II (AH Bio Fund II, L.P., first filed Dec 20, 2017).
- What is the latest AH Bio Fund fund?
- AH Bio Fund V, L.P., which first filed a Form D on Mar 20, 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 AH Bio Fund 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 AH Bio Fund 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.
