We moved [temporarily] to Qatar. We tried to sell our solutions in the US for a year w/o any success. We have spent the past two years in Qatar and have achieved far more traction and government-level engagement. The market here is small, but large enough to prove out concepts.
The obvious angle would be to prove efficacy and then try again to sell in the US (both my co-founder and I were both and raised in the US so we'd love to move back.) Another angle might be to try and sell in the UK or other single payer systems that are closer to home.
