PaxMedica, Inc. is a Private limited company (Ltd.) registered in United States under 7230892, and its current status with New York Department of State — Division of Corporations is active. The company was incorporated on 17 January 2024 and lists its registered address as ALBANY, United States. 2 shareholders are on record for PaxMedica, Inc., and since every one of them is a company rather than an individual, this particular filing does not on its own establish an ultimate beneficial owner (UBO) — identifying one would mean tracing the ownership of each shareholding company in turn.

Shareholders
2
Two shareholders are currently on record for PaxMedica, Inc., reflecting the stock ledger kept by the company under state corporate law (e.g. §219 of the Delaware General Corporation Law) rather than a public filing.
The largest of these is Vanguard Extended Market Index Fund, holding 98.2% — a majority holding — followed by Osaic Holdings Inc at 1.8%.
Because every shareholder shown is a company rather than an individual, the ownership chain continues above this level, and no beneficial owner can be established from this filing alone.
