Great questions, indeed this is a kingdom of red tape. We realized that our fist users likely will be small providers but who currently lose $$ on denied/delayed claims. Talked to the first cohort of them - rehabs, allergy clinic, men's health clinic, nursing home, etc. We signed the first rehab just 2 weeks after meeting them because we offered to solve their problem in the same way as their 3rd party billing provider does (manually finds mistakes and circles them back to clinicians) for 2x lower price tag. Then we realize this is common situation for many rehabs.
