What Is KYB?

Know Your Business, Explained

Know Your Business (KYB) is the regulatory process of verifying the identity and legitimacy of a corporate client before — and throughout — a business relationship. Where KYC verifies an individual person, KYB verifies an entity: confirming that the company legally exists, that it is in good standing with its registry, that its directors and authorised signatories are who they claim to be, and — critically — that the Ultimate Beneficial Owners (UBOs) behind the entity can be identified, verified, and screened for sanctions and PEP exposure.

KYB is far more than a tick-box exercise. Corporate structures are where most financial crime hides. Shell companies, nominee directors, multi-layered holding arrangements, and cross-jurisdictional vehicles are routinely used to obscure true ownership and control. Regulators globally — through FATF Recommendations 24 and 25, the EU AMLD, MAS Notice 626, the UK MLR 2017, and the FinCEN CDD Rule — have responded by explicitly requiring firms to look through corporate structures to the natural persons who ultimately own or control them.

One Constellation's KYB platform automates every part of that process. Company registration verification, beneficial ownership resolution across unlimited ownership layers, director and authorised signatory KYC, sanctions and PEP screening of every relevant party, and adverse media monitoring — all inside a single workflow with a full audit trail.

UBO Chain Resolution

See Through Every Layer of Corporate Ownership

A company can be owned by another company, which may be owned by a trust, which may be controlled by an individual sitting several layers removed. Our KYB engine resolves the full chain automatically — and identifies every natural person who, through direct or indirect ownership or control, is an Ultimate Beneficial Owner.

KYC vs KYB

The Difference Between Verifying a Person and a Business

KYC and KYB share the same purpose — reducing financial crime risk through identity verification — but the data, regulatory requirements, and verification techniques are fundamentally different. Applying one process where the other is needed is one of the most common compliance gaps regulators identify during supervisory visits.

The KYB Process

Three Stages From Entity to Verified Customer

Regulatory expectations for corporate due diligence break down into three clear stages. Our platform automates each of them, inside a single workflow, with full audit evidence retained throughout.

1

Entity Verification

Confirm the corporate entity legally exists, is properly registered, and is in good standing with its jurisdiction's corporate registry.

  • Company registration number check
  • Registry status & filings review
  • Trading name verification
  • Registered address confirmation
  • Regulatory licence verification
2

Ownership & Control

Map the full ownership structure, identify UBOs through indirect holdings, and document control relationships including nominee arrangements.

  • Direct shareholder verification
  • UBO chain resolution
  • 25%+ ownership threshold checks
  • Control-based UBO identification
  • Interactive org-chart builder
3

Screening & Decision

Screen the entity, every director, authorised signatory, and UBO against global sanctions, PEP, and adverse media sources — then risk-score the relationship.

  • Entity-level sanctions screening
  • Individual KYC for directors / UBOs
  • PEP & adverse media checks
  • Risk scoring & CDD tiering
  • Approval workflow with audit trail
Why Manual KYB Fails

The Structural Problems With Manual KYB — Solved

Manual KYB is slow, inconsistent, and prone to the exact errors regulators penalise. Here's what's broken in the manual process and how our platform replaces each failure mode.

🕸️

Opaque Ownership

Manual UBO reconstruction across multiple registries is error-prone and often incomplete. Our platform traces ownership chains automatically and flags gaps explicitly.

🌐

Cross-Border Complexity

Registries vary in format, language, and reliability across jurisdictions. Our data layer integrates with global registries and normalises output into a single verified record.

Weeks of Processing

Corporate onboarding can take two or three weeks manually. Straightforward corporate KYB on our platform completes in minutes to a few hours.

📋

Inconsistent Evidence

Evidence scattered across emails, shared drives, and spreadsheets makes audits painful. Every check, document, and decision lives in one immutable case file.

🛑

Missed Sanctions Hits

Manual screening misses indirect exposure through UBOs and associated parties. Our platform screens every natural person in the ownership chain.

📅

Stale KYB Records

Corporate ownership changes — directors leave, shareholders restructure. We monitor for changes and automatically re-verify when anything material updates.

KYB FAQ

Common Questions About KYB

What is KYB (Know Your Business)?+
KYB is the regulatory process of verifying the identity and legitimacy of a corporate client. It includes confirming the entity's legal existence, verifying its directors and authorised signatories, mapping its ownership structure, and identifying the Ultimate Beneficial Owners (UBOs) — the natural persons who ultimately own or control the business. KYB is required under FATF Recommendations 24 and 25 and every major AML regime globally.
What is a UBO, and why are they important?+
An Ultimate Beneficial Owner is the natural person who ultimately owns or controls a corporate entity, even when that ownership is held indirectly through multiple layers of holding companies, trusts, or nominee arrangements. Regulators require UBO identification because shell companies and complex structures are the primary tools used to hide financial crime. Most jurisdictions define UBOs as individuals with 25% or more direct or indirect ownership, or otherwise exercising effective control.
What is the difference between KYC and KYB?+
KYC (Know Your Customer) verifies individual persons through document authentication, biometric face match, and identity data checks. KYB verifies legal entities through corporate registry lookups, UBO resolution, and screening of the entity plus every relevant individual. Most regulated firms need both, because their customer base includes individuals and corporates. Our platform handles both within a single unified workflow.
How does the platform identify UBOs?+
The platform integrates with corporate registries globally, pulls shareholder and director data, and recursively resolves the ownership chain through every layer — companies, holding vehicles, trusts, and nominee arrangements. Every natural person with direct or indirect ownership ≥25%, or exercising effective control, is flagged as a UBO and KYC-verified. Complex structures are visualised in an interactive organisational chart.
How long does KYB verification take?+
Straightforward corporate KYB typically completes in minutes. Complex structures with multiple ownership layers, cross-border entities, or nominee arrangements may take a few hours, depending on registry response times and the depth of the ownership chain. Manual KYB, by comparison, routinely takes one to three weeks.
Which jurisdictions are supported?+
The platform supports corporate registry lookups across major jurisdictions globally including Singapore (ACRA), UK (Companies House), US, EU member states, Hong Kong, UAE, India (MCA), BVI, Cayman Islands, and many more. Screening data covers every global sanctions regime plus PEP and adverse media sources worldwide.
What happens when ownership changes after onboarding?+
The platform monitors corporate registries and sanctions sources continuously. Changes to directors, shareholders, UBOs, or filings trigger automatic re-verification and an alert through the compliance portal. Customer records stay accurate without manual intervention — a critical compliance benefit given how often corporate ownership shifts.
Does the platform handle trusts and nominee structures?+
Yes. Trusts, partnerships, foundations, and nominee arrangements are all supported. The platform applies the specific verification requirements for each structure type — for example, identifying settlors, trustees, protectors, and beneficiaries for trusts — and captures full documentary evidence for the audit trail.
