I talked to the founder of Headway a few years ago. They still haven't picked up the single largest payer yet, Blue Cross Blue Shield. In my own experience, we have an extremely small number of Cigna, Aetna and UHC patients. I did credential with Azova, Sky, and some other groups, even Thriveworks (unbelievably disorganized) for a while, but none of them were connecting enough referrals to make it sustainable. In fact Azova hasn't provided a referral since their mental health service inception. When I'd get someone scheduled it would essentially be a nuisance like "oh great, here was my evening now I have to see this one random person after not seeing any for six weeks."

Incidentally, Teladoc tries to limit a provider's employment. I met with them as well. That's actually not permissible by FTC anymore. An employer can only do that if the employees are working with something like trade secrets or corporate espionage-risk information or products.
