The Problem
Handling Private User Data Is Risky, Costly, and Frustrating
Privacy is
non-negotiable
Users today know the value of their data. They expect full control — over who can access it, for what purpose, and for how long. Anything less erodes trust.
Official APIs are
limiting
Platforms often neglect API development, leaving data access limited in both scope and granularity, making it harder to get what you truly need.
Intermediaries add
cost and friction
Relying on third parties to access user data drives up costs, slows onboarding, and adds unnecessary risk.
The Solution
vouch Redefines
User Verification
Customizable Zero-Knowledge
Attestations
Create a direct verification channel that keeps customers in full control of what they share and how they share it. No intermediaries. Privacy is the default.
Fastest Access
to Consumer Private Data
Verify any private data available in web2 (websites, apps, emails) — plus access information not exposed through APIs. Get the data you need, instantly and securely.
Better Verification
at a Fraction of the Cost
Cut out intermediaries to lower verification costs, reduce complexity, and speed up onboarding.

FAQs
Your Questions, Answered
What features come with vouch?
vouch enables businesses to receive verified attestations directly from users, without building complex integrations. You handle only the minimal sensitive data required for your use case, with the rest staying securely with the user. You get customizable verification workflows, zero-knowledge attestations, and access to private data beyond standard API limits, all with hands-on support from our team.
How does vouch ensure data security?
All verification happens on the user’s device, with no private data of your consumer stored on our servers. Only cryptographically verified attestations are shared, and the underlying information is never revealed. This zero-knowledge approach eliminates PII handling and significantly reduces compliance burden.
What kinds of attestations can users create?
Businesses can request proofs for financial data, identity information, address verification, account ownership, transaction history, professional credentials, and more. Our system supports virtually any digital claim you need to verify, without requiring direct API access to source platforms.
How do we integrate vouch into your onboarding process?
Integration is fast and supported by our team from start to finish. We configure your required claims, provide you with a simple API or widget integration, and help you test and launch. Most customers are live within days, not weeks.
Is there a free version of vouch?
We don’t currently offer a self-serve or free trial. Instead, we work directly with each customer to get you live quickly. From your first conversation with us, we scope your requirements, configure your workflows, and handle setup — so you can start verifying data fast.
How can I learn more or get started?
You can contact our sales team directly through our Get Started form or by emailing namita@getvouch.io. We’ll set up a quick call to understand your needs and walk you through how vouch can work for your business.
