CASTELLUM CORPORATION
CASTELLUM CORPORATION is a registered legal entity registered in United States under 07791635, and its current status with Virginia State Corporation Commission is inactive. The company was incorporated on 13 June 2014 and lists its registered address as United States. 5 shareholders are on record for CASTELLUM CORPORATION, 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. This profile is sourced directly from Virginia State Corporation Commission and was last updated on 4 October 2026.

Shareholders
5
Five shareholders are currently on record for CASTELLUM CORPORATION, reflecting the stock ledger maintained under state corporate law (e.g. §219 of the Delaware General Corporation Law) rather than a public filing.
The largest of these is Essex Investment Management Co LLC, holding 23.4% — the largest recorded stake — followed by Vanguard Group Inc at 13.9%; the remaining 3 shareholders shown hold smaller stakes.
The register reports 15 shareholders in total, though only the top 5 by holding are shown in this view.
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.

Officers
5
The President Of Ssi of CASTELLUM CORPORATION currently on record is Emil Kaunitz; five officers are currently on record for CASTELLUM CORPORATION, filed with Virginia State Corporation Commission.
The register reports 11 officers in total, including past appointments, though only the 5 most relevant records are shown here.
Management authority at CASTELLUM CORPORATION sits with these individuals, not with shareholders, who are covered separately and hold ownership rather than control.
The source filing doesn't specify representation authority — whether officers can act individually or must sign jointly to bind the company — so that detail isn't available here.
Group Structure
CASTELLUM CORPORATION has no recorded parent company — it sits at the top of its own group structure, with 4 subsidiaries recorded beneath it across 1 jurisdiction. Each of these downward relationships is derived rather than filed: resolved by matching entities across the registry network, not stated directly in a single document.
Those 4 subsidiaries span United States jurisdiction, though this list should not be read as complete — subsidiaries only become visible here where shareholder data has actually been filed with a register, so holdings in jurisdictions without that filing simply won't appear.
