Wonder Mack Excalibur LP
New Form D on file · 2026-09-16 · the record
What the record says
Everything on the record so far — 2026-09-03 to 2026-09-17. This window lengthens as filings accumulate; it is not yet a year. 172 filings in Other, totalled by day. The dot is this raise, $4M, on the same scale — one filing against the whole group's total, so it sits low by construction.
