As part of the US regulation, we are required to perform KYC (Know-your-customer) on every person that uses our platform.
As part of the customer review, we are required to collect social security number. This does not impact your credit score, and your SSN is held securely and encrypted with our third party data provider Persona (the leading compliance platform in the space providing KYC for Square, Brex, and more).
We take customer information and security incredibly seriously. We only collect what is required of us by federal regulations. We researched all of the compliance platforms, and we ultimately chose Persona, given their track record, security, and user experience.
