KYB software that verifies the companies you do business with.
KYB software, short for Know Your Business, verifies a company before you work with it: that it is legally registered, who owns and controls it down to the ultimate beneficial owners, and whether the company or its people appear on sanctions, PEP or adverse media lists. KYCK runs those checks as one flow, from a self-serve portal to an approved file with the evidence attached.

What a KYB check covers
A KYB check covers five things: the legal entity, identified from its registration documents rather than its email signature; its ownership and control, down to the ultimate beneficial owners; the people who run it; its exposure to sanctions, politically exposed persons and adverse media; and the documents that prove each of those facts. KYCK collects and checks all five in the same file.
Documents read, not retyped
Counterparties upload certificates of incorporation, licences and registry extracts through the portal, and KYCK extracts the data from them, so analysts confirm fields instead of typing them. Each extracted value stays linked to the page it came from, and a legal name the counterparty typed is never silently overwritten by an automated read.
Ownership to the last layer
KYCK unwinds layered ownership to the ultimate beneficial owners, applies the 50 percent rule where sanctions law requires it, and checks the chain against the documents. Every person it finds is screened on the same pass, because a clean company with a designated owner is not a clean company.
One screening pass on the company and its people
Sanctions, PEP and adverse media checks run on the entity, its directors, shareholders and beneficial owners together, against lists including OFAC, the EU consolidated list, UK OFSI and the UN. Match scores are explainable, so a reviewer can see which fields aligned and defend a clear line by line. The full list sits in the sanctions authorities directory.
A self-serve portal instead of an email chain
You send one invite. The counterparty completes a KYB questionnaire built from your own template, uploads its documents and signs the NDA where one is required, while you follow its progress on your side. Chasing happens inside the system, not across a week of email threads.
Decisions that hold up later
Multi-level approval routes each file to the people you assign, every sign-off is timestamped, and the finished file exports as a disclosure package for banks, auditors and supervisors. Any counterparty can be re-screened against current lists on demand, and scheduled rescreening is available as an add-on.
KYB software with an API, or without one
Teams without engineers run KYB entirely in the platform. Teams that want KYB inside their own systems use the KYCK KYB API: REST endpoints to create counterparties, run screenings and fetch the evidence behind any decision, with webhooks on completed screenings and status changes. API access is included on the Professional and Enterprise plans; see pricing for the tiers.

If you are weighing KYB software, our comparison of seven KYB tools says plainly what each one is best at, including when another tool is the better choice. For individual identity checks with selfies and liveness, a consumer identity platform fits better; the difference is explained in KYB vs KYC.
Frequently asked questions
What is KYB software?
KYB software automates Know Your Business checks: it verifies that a company is legally registered, identifies who owns and controls it, screens the company and its people against sanctions, PEP and adverse media lists, and records the evidence behind the decision. It replaces the spreadsheets, registry searches and email chains most teams start with.
What is the difference between KYB and KYC?
KYC verifies a person, usually with an identity document. KYB verifies a business: its registration, its ownership and the people behind it. A KYB check usually ends with identity checks and screening on those people, such as directors and beneficial owners, which is why most firms dealing with companies need both.
What does a KYB check include?
At minimum the legal entity and its registration details, the ownership chain down to the ultimate beneficial owners, the directors and other key people, sanctions, PEP and adverse media screening on all of them, and the documents that evidence each fact. Higher-risk counterparties get enhanced checks on top.
How long does a KYB check take with KYCK?
The workflow itself runs in minutes once the counterparty completes its form: documents are extracted, screening runs automatically and the file routes to approval. End to end, most onboardings finish as fast as the counterparty responds.
Does KYCK have a KYB API?
Yes. The REST API covers counterparties, screenings, evidence and webhooks, with separate sandbox and production keys. It is included on the Professional and Enterprise plans.
Is KYB required by law?
For regulated firms, anti-money laundering laws in the UAE, the UK and the EU require you to identify a corporate customer and its beneficial owners before establishing the relationship. Businesses outside those rules still face sanctions law, which applies to everyone, and banks that ask for evidence of who their clients trade with.
