Building a Validation Chain That Holds Up in Audit
Separation of duties, evidence retention and what an auditor actually asks to see.

Built for group finance departments
Hyperobust brings together complex-structure steering, cross-border tax compliance and subsidiary audit in a single workspace, under the group's control.
Sealed perimeter
Every entity, file and document belongs to a group perimeter. Isolation is enforced by the database, not by the interface.
Group structure
Parent, subsidiaries, jurisdictions, consolidation method. Effective interest is computed across the full ownership chain.
Cross-border tax
Pillar Two, country-by-country reporting, DAC6 and withholding tax, built on one entity register.
Tamper-proof audit trail
Who did what, and when. The log is written by database trigger: nobody, not even an administrator, can amend it afterwards.
The group perimeter modules
Structure, tax, compliance and committees. Every module works on the same perimeter and leaves the same trail.
Group structure
Org chart, holdings, jurisdictions and consolidation method for every entity
Cross-border tax compliance
Pillar Two, country-by-country reporting, DAC6 and withholding tax on intra-group flows
Filing calendar
Directive deadlines per jurisdiction, computed from your financial year end
Data sovereignty
Access log and full reversibility export of the group perimeter
Treasury forecast
Which subsidiary runs short of cash, and when
Committees and meetings
Agendas, minutes and preparation for group committees
Committee notes
Six templates for the notes taken to a group committee

How It Works
01
Set Up Your Group
Declare your entities, invite your finance teams and assign enterprise roles: Group Admin, Auditor, CFO Validator.
02
Run the Compliance Pipeline
Move each subsidiary audit through data ingestion, gap and risk analysis, C-Level validation and certified closing.
03
Analyse and Justify
Read the macro regime, quantify the gaps and let the Oracle draft the rationale that goes into the file.
04
Certify and Archive
Only a CFO Validator certifies a closing, and the audit trail keeps an immutable record of who did what, when.
Pillar Two, jurisdiction by jurisdiction
The effective tax rate is computed on each jurisdiction's aggregate, net of the substance-based exclusion. Wherever it falls below 15%, the top-up tax appears.
| Jurisdiction | Qualified income | ETR | Top-up tax |
|---|---|---|---|
| Ireland | €140M | 12.5% | €3.4M |
| Portugal | €60M | 9% | €3.2M |
| France | €95M | 25% | — |

Frequently asked questions
What the platform does, what it does not do, and what you need to start.
It is your group and all of its entities. Everything you enter belongs to it: subsidiaries, files, tax figures, documents. The isolation is not a display rule but a database rule — a query issued from one group physically cannot return another group's rows. Nothing can be entered before a perimeter exists; it is the first screen after sign-in.
With entities. Declare your subsidiaries, holdings and branches: an entity entered once feeds all four tax modules, the org chart and the closing pipeline. Then link them together — who owns whom, at what percentage — so the org chart derives the chained interest percentages. Finally, invite your teams with their role.
Four. The Group Admin administers the perimeter and its settings. The Auditor prepares files and submits them for validation. The CFO Validator certifies. The Viewer reads without writing. A file prepared and certified by the same person is flagged as such in the closing dossier: separation of duties is established, never assumed.
The effective tax rate per jurisdiction, the substance-based income exclusion on the dated transitional schedule, the €750M threshold, de minimis on a three-year average, the GloBE loss election, the transitional CbCR safe harbour and the QDMTT credit. The result is allocated across entities and reduced to the group's share at the interest percentage read from the org chart. Out of scope, and the interface says so: the UTPR.
No. It is a decision-support simulation. It is filed nowhere, it does not commit your group, and it replaces neither your tax adviser nor your statutory auditor. The certified closing dossier states what it does not attest — it never says the accounts are correct.
Because a stale table is worse than no table. There are thousands of tax treaties, revised with every protocol, and a rate displayed with confidence would be applied without being checked. The two EU directives — parent-subsidiary and interest-royalties — are rules, so they are in the code. The treaty cap is entered by hand, with the article that grounds it.
At any time, and without us. The reversibility export returns the whole perimeter as a JSON object readable without the platform: entities, org chart, files, logs. No pagination, no cap, restricted to the Group Admin, and the export writes itself to the access log. Hosting, keys and subprocessors are contractual matters; the Sovereignty screen states precisely what it covers and what it does not.
It answers on method, regulatory framework and drafting. It does not read your database to produce figures, and no module generates a numeric recommendation from a model: the figures you see come from what you entered, computed by functions whose code is auditable and tested.
