THOUGHTWORKS HOLDING, INC
THOUGHTWORKS HOLDING, INC is a registered legal entity registered in United States under 6513361, and its current status with Delaware Division of Corporations is active. The company was incorporated on 8 April 2018 and lists its registered address as United States. 5 shareholders are on record for THOUGHTWORKS HOLDING, 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. This profile is sourced directly from Delaware Division of Corporations and was last updated on 8 October 2026.

Shareholders
5
Five shareholders are currently on record for THOUGHTWORKS HOLDING, 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 Siemens Ag, holding 26.7% — the largest recorded stake — followed by Vanguard Group Inc at 11.6%; the remaining 3 shareholders shown hold smaller stakes.
The register reports 20 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.

The register reports 14 officers in total, including past appointments, though only the 5 most relevant records are shown here.
Management authority at THOUGHTWORKS HOLDING, INC 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
THOUGHTWORKS HOLDING, INC sits 1 level below its ultimate parent, Tasmania Midco LLC, registered in United States. 1 subsidiary is recorded beneath it, across 1 jurisdiction. The full chain up to Tasmania Midco LLC is derived by walking shareholder filings across jurisdictions; no link in it is independently corroborated by THOUGHTWORKS HOLDING, INC's own shareholder record. 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 1 subsidiary spans 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. One of the 1 go a level deeper still, with its own further subsidiaries recorded beneath it — additional ownership layers this view doesn't expand.
