FAQ
What is KYB verification and why do businesses need it?
Know Your Business (KYB) verification validates a company's legitimacy, ownership structure, and compliance status. It's required by AML regulations to prevent money laundering, identify beneficial owners, and ensure you're partnering with legitimate entities. KYB helps businesses avoid fraud, meet regulatory requirements, and build trust with financial institutions.
What business documents can Signzy verify for KYB compliance?

Our platform handles everything from US LLC formations to international corporate filings.
How does Signzy detect shell companies and fraudulent businesses?
Our AI-powered document forensics analyze inconsistencies in corporate filings, validate beneficial ownership chains, and cross-reference multiple databases in real-time. We flag suspicious ownership structures, dormant entities, and document tampering. Combined with global registry validation, shell companies and synthetic business identities can't slip through.
