RHYTHMONE LIMITED is a Private limited company (Ltd.) registered in United Kingdom under 06223359, and its current status with Companies House is intermediate. The company was incorporated on 23 April 2007 and lists its registered address as Brighton, United Kingdom. 1 shareholder is on record for RHYTHMONE LIMITED, 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 Companies House and was last updated on 9 October 2026.

Shareholders

1

One shareholder is currently on record for RHYTHMONE LIMITED, held on the Confirmation Statement (CS01), filed under the Companies Act 2006.

The largest of these is TREMOR INTERNATIONAL LTD, holding 100% — a majority holding.

Because the 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

Three of the 5 officer records shown for RHYTHMONE LIMITED are current appointments, filed with Companies House. Yaniv Carmi (appointed 2019-04-01) and Ofer Druker (appointed 2019-04-01) both serve as Director; Amy Rothstein (appointed 2018-03-19) serves as Company Secretary. The remaining 2 records shown (Eric Singer and John Mutch) are former appointments that have since been resigned.

The register reports 26 officers in total, including past appointments, though only the 5 most relevant records are shown here.

Management authority at RHYTHMONE LIMITED 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

RHYTHMONE LIMITED sits 1 level below its ultimate parent, TAPTICA INTERNATIONAL LTD. 4 subsidiaries are recorded beneath it, across 1 jurisdiction. The full chain up to TAPTICA INTERNATIONAL LTD is derived by walking shareholder filings across jurisdictions; no link in it is independently corroborated by RHYTHMONE LIMITED'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 4 subsidiaries span United Kingdom 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 4 go a level deeper still, with its own further subsidiaries recorded beneath it — additional ownership layers this view doesn't expand.
