Anyone annoyed with not being able to see who is actually the instructors and who is offering courses plus other details can take a look at what is listed over at StackSocial , I believe that it is same bundle that they sell there :
https://stacksocial.com/sales/google-guru-bundle
But in short all courses seem to be hosted by StackSkills eLearning with different instructors…
Provided that it’s the same course that they sell then you can also see “specs” and detailed instructor info by going to the Stacksocial page and then first click what part of bundle that you want info about over at the left side of page and then at right side of page click the plus signs below course description to reveal more info where it says respectively : “Compatibility” , “Specs” and “Instructor”
…
