- What is the latest ONETAIL HEDGEHOG FUND fund?
- OneTail HedgeHog Fund III LP, which first filed a Form D on Aug 20, 2018. Its own page carries the filed terms, the people named on the form and every filing on EDGAR.
- Who is the adviser to the ONETAIL HEDGEHOG FUND funds?
- Longtail Alpha, LLC (RIA, CRD 282615), joined from Form ADV Schedule D, where an adviser lists each private fund it advises and the fund's Form D file number.
- How much have the ONETAIL HEDGEHOG 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.
