KYC Has a Waste Problem. Self’s Pre-KYC is Here to Solve It. 

Companies lose money every time an applicant is rejected mid-compliance screening. Self's proof-of-human and identity verifications power advanced review to reduce KYC friction and loss, while preserving user data privacy. 

Compliance screening at scale is expensive: companies lose billions annually on failed KYC attempts. For high-volume platforms and global products, a significant share of that cost is avoidable: screening failures on applicants whose age, nationality, or sanctions status disqualified them from the start.

There must be a better way to reduce KYC spend, the amount of data companies require users that might not even be eligible for their services, and onboarding friction. 

Now there is. Introducing Self Pre-KYC, an enterprise offering leveraging privacy-first identity infrastructure to improve the onboarding experience for businesses and their customers alike. 

Where KYC Funnels Go Wrong

Traditional KYC processes charge per customer without a pre-screening step, putting eligibility second. Users complete high-friction document uploads, hand over their private information, and wait for processing, with many being rejected for reasons that could have been identified upfront. Up to 60% of users abandon the process of opening a digital bank account before completion. 

Average annual spend on AML and KYC operations now stands at $72.9 million, and the industry largely treats failed checks as unavoidable overhead. Self's Pre-KYC is here to change that, protecting user privacy while simplifying compliance screenings at lower cost.

How Self’s Pre-KYC Works

Pre-KYC is a cryptographic pre-screening layer that sits at the top of the onboarding funnel, before any billable KYC check is triggered. Using zero-knowledge proofs generated locally on a user's smartphone, Self verifies whether an applicant meets categorical eligibility criteria: age requirement, nationality, sanctions status, and document validity.

If the proof passes, the user proceeds to full KYC. If it fails, they're stopped at the gate. 

No PII changes hands, company servers don't touch the data of  identified users who don't qualify. The proof is generated on-device using the user's biometric ID and verified cryptographically. The only thing businesses receive is a pass or fail.

What Information Gets Verified

• Age verification: Confirm the user is over 18 (or any age threshold you define) without collecting their date of birth.

• Nationality screening: Allow or deny applicants based on country of origin, aligned with company licensing or compliance requirements.

• Sanctions checks: Screen against OFAC and other allow/deny lists before any billable event occurs.

• Document validity: Confirm the user's ID is current and authentic before it reaches a manual or automated review queue.

The Business Case

For a company onboarding 10,000 new clients at $1,500–$3,500 per review, KYC spend alone can run into the tens of millions annually. Filtering even a modest share of ineligible applicants before they trigger that cost changes the unit economics meaningfully.

When ineligible applicants are filtered out, the ratio of users entering full KYC to users completing it will also significantly increase. As a result, businesses will have reduced PII storage liability. 

For teams running waitlist campaigns or launching in new markets, Pre-KYC also functions as an eligibility pre-screen before a full rollout, letting you qualify an audience without triggering compliance processes for users you can't yet onboard.

Privacy by Design

Self generates proofs on the user's device using their government-issued biometric ID. The output is a zero-knowledge proof that confirms a specific claim (that a user is over 18, or not from a restricted country) without transmitting the underlying data to anyone. Your servers receive cryptographic confirmation and nothing more. The user's personal data stays on their device, and your liability for rejected applicants drops to zero.

This transforms traditional KYC, where collecting and storing personal data is a prerequisite to screening, to only collecting information when absolutely necessary.
