About Berbix

Berbix is building identity verification and fraud deterrence as a service. Founded by the former engineering and product leaders for Trust & Safety at Airbnb, we empower companies to confidently answer the question: “Are you who you say you are?"

This is a question many online platforms need to answer. We've started answering this question by creating four lightweight hosted verifications:

  • Verify an email address
  • Verify a phone number
  • Scan a photo ID
  • Confirm a street address

We then have an add-on framework that integrates with multiple backend providers to further increase our confidence that users on the other side of the screen are who they say they are. We are targeting three primary use cases:

  1. Age Verification

Ordering alcohol, nicotine, and marijuana online is quickly becoming the norm. Platforms need a confident way to ensure these orders are being made by and delivered to consumers above a certain age. Many have regulatory requirements to collect an ID. We also help other age-restricted services like online gambling.

  1. Fraud Deterrence

Every online platform has a fraud problem. By offering platforms a range of user-facing verifications, we're adding additional tools to their proverbial toolbox to help fight fraud. For example, requiring phone verification of a bona fide mobile number (as opposed to a virtual number) for high-value or otherwise riskier transactions.

  1. KYC ("Know Your Customer")

Cryptocurrency and other FinTech startups have various compliance requirements for identifying account holders. We provide a secure and user-friendly way to collect photo IDs from their users.
