I’ve built similar multi-vendor platforms with strict vetting, so I’d focus on designing a smooth but airtight onboarding flow that feels less like a DMV visit and more like a red-carpet security check. The biggest challenge will be balancing rigorous compliance checks with a frictionless user experience—solvable through staged verification and clear UX microcopy. Before diving in, could you share how you envision scaling the manual review process when hundreds of professionals start knocking at the digital door?
