Do you support credentialing, or plan to?

Not currently. In the UK we run a service called Docs, which helps physicians understand the credentialing process, store their documents — diplomas, licenses, health screenings, registrations, certifications, board certifications, insurance — and share them with agency credentialing teams in one click. It has sped up the early phase of credentialing there. If there's demand for it in the US, we'll consider launching something similar.
