We don't think developers should have to reinvent the wheel, or cobble things together to build a customized experience. You're usually not writing 50 lines of javascript one time only and calling it a day - you are changing your flow all the time, as soon as you see evidence for how to make it better. Onboarded is a tool that will make that process of learning and iteration much more efficient (and thus faster and cheaper). And there's no reason you couldn't integrate with Segment too.
