Although it is nice to see Joomlart expand its offerings but really think you should get a handle on what you have first. You introduce ja builder to broaden your membership but to date it is not stable. On a fresh install on joomla 3.7 here are just a couple issues that make it unusable.
1) The front end editor for text simply does not work at all. Bold, Italics, color, simply non of it works.
2) Using an video for overlay. It does insert the youtube video however to the public there is a red play button but it does not work on mobile devices.
This is just a couple that stand out but without them have to stop using the builder. Posts on here to not get responded to. Would question your ability to support all the other companies you are acquiring if you cannot take care of your existing customers. Look like its time to go back to quix. Please let me know when you think it is really stable.
