Introduction

AI-Resilient Verification

vouch enables businesses to verify user-owned data with cryptographic proofs that defeat fraud, including AI deepfakes. No document uploads. No manual checks.

Traditional verification uses either document uploads - vulnerable to deepfakes and invasive to privacy - or APIs with limited data access. vouch solves this through:

• Universal data access: Verify data from any source users can access online.
• Zero integration: No API integrations required; works with any platform.
• Privacy-first: Users control their data; you receive only verified proofs.

Products

vouch offers three product lines, each designed for specific verification needs.

Non-Doc KYC & KYB

Verify individuals and businesses without document uploads or manual checks. Cover identity, address, age, ownership, source of funds, balance, income, and key KYB checks for onboarding and compliance. See implementation example →

Candidate Authenticity

Built for hiring, tenant screening, lending, and eligibility checks where accuracy and UX matter. Confirm identity, employment, income, and professional claims using verifiable data from payroll, banks, government records, and professional platforms. See implementation example →
