Know Your Business (KYB) verification software is essential for fintechs, SaaS platforms, marketplaces, and financial institutions that onboard and work with other businesses. This repository provides an overview of:
- Key criteria for choosing KYB solutions
- Must-have features for developers and compliance teams
- Top 6 KYB providers in 2025
KYB software automates the process of verifying whether a business is legitimate, compliant, and not engaged in illicit activities. It protects companies from fraud, reduces regulatory risk, and accelerates onboarding.
Typical checks include:
- Business registry verification
- Ultimate Beneficial Ownership (UBO) discovery
- PEP and sanctions screening
- Adverse media monitoring
- Ongoing re-verification and alerts
When evaluating KYB providers, consider these core criteria:
- Registry Coverage: Global vs local, depth of registries, update frequency
- UBO Identification: Ability to uncover ownership hierarchies
- Compliance Screening: Sanctions, PEP, watchlists, adverse media
- Integration & APIs: RESTful APIs, SDKs, webhooks, sandbox support
- Customization: Rules engine, modular workflows, fallback logic
- Monitoring: Ongoing alerts for changes in ownership, sanctions, or risk status
- Auditability: Exportable logs, version history, compliance reports
- Pricing Model: Per verification vs subscription, hidden costs
- Support & SLAs: Developer support, uptime guarantees, response times
Modern KYB solutions should provide:
- API-first design for easy integration
- Coverage across multiple jurisdictions
- UBO checks and corporate hierarchy discovery
- Automated AML screening (sanctions, PEPs, adverse media)
- Ongoing monitoring, not just one-off checks
- Audit trails for regulatory inspections
- Developer-friendly docs and SDKs
- Real-time or low-latency verification
