Purpose
Brex’s onboarding system verifies applicants and synthesizes KYC and underwriting evidence into decisions for its operations team.
How it works
Representative workflow: customer application → onboarding decision or analyst escalation. Research details
Specialists segment businesses, verify documents and identity, and reconstruct financial profiles.
A decision agent combines policy, evidence and confidence; uncertain cases go to analysts.
Where people stay involved
Each scope pairs its normal attention boundary with supporting evidence. See the supervision definitions for the level mapping and limits.
