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.

KYB helps businesses avoid fraud, meet regulatory requirements, and build trust with financial institutions.

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.
