Know when new evidence may change the ownership picture.

Monitor supported source updates concerning shareholders, UBOs, controlling entities and group structures. Each alert explains what was observed, the available date context and which prior ownership conclusion may be affected.

The question that matters

Did the record change—or did the person behind the company change?

Zavia separates supported ownership-relevant source updates from routine company updates, then compares the prior and latest observed ownership paths so a reviewer can assess potential impact.

Illustrative conclusion

A new filing replaced Cedar Holdings with Rowan Capital at 60%. Following the new branch changes the calculated UBO from Daniel Ionescu to Elena Popa, with one new gap flagged for review.

Built for investigation

Move from a company name to a conclusion you can explain.

Each step preserves the legal entities, relationships and evidence that produced the result.

01

See before and after

Each supported alert records the prior and latest observed owner, percentage, affected ownership level, available filing or effective dates and the observation date.

  • Prior and latest observed paths
  • Available filing and effective dates
  • Source preserved with event
02

Understand the ownership impact

Plain language explains whether a direct shareholder, calculated UBO, threshold result or group perimeter may have changed.

  • Potential control consequence explained
  • Threshold movement visible
  • Incomplete paths flagged
03

Maintain an auditable timeline

Reconstruct what was known at each point, including periods when a branch was unresolved or a conclusion changed because new evidence arrived.

  • Latest observed and historical state
  • Source corrections retained
  • Filter by event and evidence
Evidence architecture

One answer. Four clearly different evidence states.

An alert should carry enough evidence to reproduce the changed conclusion—not merely announce that something happened.

Government registry

The legal entity, relationship, source and record date as reported by an official registry.

Reviewed public evidence

Relevant public disclosures are reviewed and labelled separately from official registry facts.

Zavia calculation

Indirect interests are calculated from supported paths, with the formula available to reproduce.

Unresolved

Missing, conflicting or incomplete ownership stays visible instead of being replaced by a guess.

Where it fits

Ownership intelligence for decisions that cannot rely on a black box.

01

Periodic KYB review

Review supported ownership-relevant source updates after onboarding.

02

Supplier monitoring

Follow changes across critical counterparties.

03

04

Workflow automation

Use the same evidence everywhere

For analysts, systems, agents and data platforms.

Depending on the agreed implementation, monitoring can be delivered in the web platform, through the Ownership and UBO API, to authorized agents through MCP, in bulk data or as a monitored change workflow.
