Ownership Graph

A service page names the company that operates it. This records who owns that company, taken from the register that publishes it, and says where the public record runs out.

Every entity below was fetched from its own register on , not looked up in a company-data reseller and assumed. This is a small graph on purpose: an ownership link is recorded only where a primary record states it, so the absence of a link means nothing was published, not that a company stands alone.

Evidence tiers

REGISTRY RECORD
Read directly from the official register's own record or API on the retrieval date. The register is the authority for this fact.
REGULATORY FILING
Read from a filing the entity was legally required to make to a regulator (SEC exhibits, annual reports). Authoritative for the filing date, not necessarily current.
REGISTRY DATA
Read from a service that republishes official registry data. Accurate in practice, but one step removed from the register.
COMPANY STATEMENT
Stated by the entity itself on its own governance or legal page. This is how most non-equity control arrangements become knowable at all, and it is not independently verifiable.

Link kinds

SHAREHOLDER
Holds equity in the child entity. The percentage is recorded where the register publishes it.
PRINCIPAL SHAREHOLDER
Named by the entity as its controlling or primary shareholder without a published percentage.
ABSORBED
The child entity was merged into the parent and struck from the register. The parent is the legal successor.
PREDECESSOR
An earlier, separate legal person that ran the service before the current operator. Not a rename: this entity was dissolved.

One company, several listings

The directory lists products. These are the cases where separate entries share a single legal operator, which is the thing a per-service listing cannot tell you: comparing them compares products of one company, not independent alternatives.

Fondation Proton owns Proton AG

COMPANY STATEMENT
Relationship
PRINCIPAL SHAREHOLDER
Retrieved

As Proton's primary shareholder, the foundation exercises its control to ensure that Proton does not deviate from our mission. No change of control of Proton can occur without the consent of the Foundation.

What this does and does not showBoth entities are registry-confirmed, but the shareholding between them is not. Swiss law does not require a company to publish its shareholders, so this edge rests on Proton's own account of its governance and cannot be checked against Zefix.

Fusion: reprise des actifs et passifs de ProtonVPN AG, à Plan-les-Ouates (CHE-496.963.746), selon contrat de fusion du 19.06.2020 et bilan au 31.12.2019.

What this does and does not showRecorded on both sides of the register: Proton AG lists ProtonVPN AG under companies taken over, and the ProtonVPN AG record names Proton AG as the entity that took it over. The VPN product has had no separate company since.

Holding
82.5%
Held since
Retrieved

The Czech commercial register lists SatoshiLabs Group a.s. (IČO 08685916) as holder of an 82.5% share in Trezor Company s.r.o., entered 2026-04-09 and not struck.

What this does and does not showThe remaining 17.5% is held by four named individuals at 5%, 5%, 5% and 2.5%. Czech law publishes the shareholders of a s.r.o., which is why this chain is visible at all; the equivalent Swiss and Swedish holdings are not public in the same way. The holding was 96.5% between 2023-11-24 and 2026-04-09.

Entities

Every legal person referenced above, with the identifier its own register issues. Where a company was renamed, the former name is listed against the same registration number, which is what proves it is one continuous entity rather than a successor.

Proton Technologies AGrenamed
Renamed by the same legal person, not a new company. The Swiss Official Gazette entry of 18.10.2021 reads 'Nouvelle raison sociale: Proton AG', with the statutes modified on 30.09.2021. The UID is unchanged either side of the rename, which is what proves it is one entity.
ProtonVPN AGabsorbed
Recorded on both sides of the register: Proton AG lists ProtonVPN AG under companies taken over, and the ProtonVPN AG record names Proton AG as the entity that took it over. The VPN product has had no separate company since.

A second, unrelated Proton AG exists in the Swiss register (CHE-363.321.658, seat Zürich, ehraid 1513956). It is a namesake with no connection to the mail and VPN business, and the UID is the only thing that separates them. Any lookup by name alone will return both.

The registry record shows no parent company of its own, so this is the top of the Swedish chain. Mullvad's own about page attributes ultimate ownership to its two founders, which is a statement by the company rather than a registry fact.

The UK company was dissolved in 2021 and the service continued. Whatever operates it now is not this company, and the terms do not say what it is.

Named in the service's own terms without a registration number or jurisdiction, and no register consulted on 2026-08-09 returned a matching current company. The operator is therefore identified but not verifiable, which is a materially weaker position than every other entity on this page.

Every entity below was fetched, not searched for and assumed.

5 of the entities here operate a listed service. Most privacy companies publish no ownership at all: Swiss and Swedish registers do not list shareholders, so a chain that stops is a limit of the public record rather than a finding about the company. Nothing on this page should be read as an audit.
