Early stage here - self funded. After many years in land mobile radio industry, I decided to start my own thing. Hand held radios are still around, and will be, for many years. We're making them much better - the range, battery life, .. and open sourcing them.
As other said, development can be very expensive and iterations long, unless you're smart about it.
