I think you are right. For my company is also hard to start working with haxe because:
1) Not have good enough IDE (wit full debug support all targets ) for all OS ( Win, Mac, Linux). At the moment have many:
IDE: haxedevelop(falshdevelop),intellij idea, visual studio(haxe plugin),atom
2) Mobile native plugins : missing or depends of framework
3) Which framework to choose and is in active development ?
Nme, Openfl, snowkit, Kha, heaps
You can check this topic what other company looking for:
I really like haxe , but with above issues maybe I will be the only one (n the company) use it for personal projects and in some moment our company will start to use Unity or some javascript library in the post flash era
