02 / In plain words
What KYB means
KYB (know your business) is the procedure for checking a company as a client, the business counterpart of the KYC (know your customer) familiar to individuals. When a bank, payment system or partner starts working with a legal entity, it must understand what kind of company it is: who really owns it, what it does, where its money comes from and whether there are risks.
KYB examines the ownership structure (down to the ultimate beneficial owners, UBOs), constitutional documents, type of activity, financial history and reputation, and runs the company and its owners through sanctions and other lists. The aim is to make sure that the legal entity does not conceal anonymous owners, money laundering or other risks and that the business is transparent and lawful.
For entrepreneurs and holding company owners this is a key point: opening an account for a company or starting to work with a partner bank is impossible without passing KYB. A non-transparent structure, concealed beneficial owners or vaguely described activity are a red flag and grounds for refusal. We help build and present the company’s structure transparently so that it passes the business check successfully.
A case from practice
A holding company owner wants to open a corporate account. The bank launches KYB and requires disclosure of the whole ownership chain down to the ultimate beneficial owners. With a transparent structure and documents prepared in advance, the company passes the check; had the owners been concealed, a refusal would have followed.
Where KYB is applied
- Opening a company account
- Working with partner banks
- Checking counterparties
- Connecting to payment systems
- Disclosing a legal entity’s beneficial owners

06 / Expert advice

How to prepare in advance
Before opening a corporate account or starting to work with a bank, the structure is built and documented transparently: the ultimate beneficial owners (UBOs) are disclosed, constitutional documents prepared, the activity clearly described and the source of funds evidenced. The company and owners are checked against sanctions lists. Then KYB goes faster, and the business gains access to financial services.
What we do for you. We help businesses pass KYB: we build and present the company’s structure transparently, disclose the ultimate beneficial owners and prepare the documents and evidence of activity and funds. That way opening an account and working with partner banks succeed rather than running into refusal because of opacity.
