Incorta satisfies Arthur C Clarke's third law: “Any sufficiently advanced technology is indistinguishable from magic”. I have yet to find an analytics problem that I cannot solve with Incorta. The ease of use and performance of the platform is simply amazing.
Secondly (but not in importance) is the dedication of the support team. They consistently exceed my expectations.
Thirdly, business schemas are brilliant! These provide a capability that is missing from other systems, The ability to provide a packaged set of metadata in a user-specific dialect is disruptive in the analytics platform world.
Fourthly, formulas are another area of brilliance. I can use base data and build fields that make analyses easier and more functional than SQL alone.
Session variables are the batman utility belt of the tool. I have several dozen of these that simplify formulas and filters. In fact, there are certain date base filters that would not be possible without session variables. Review collected by and hosted on G2.com.
