Thinking of analysing 20+ IH interviews, what would you like to learn from it?

I want to analyze 20+ IH interviews and find out what are the commonalities/differences between these successful products and present the data using visualizations. It will also serve as a cheat sheet for newbies.

Here are some parameters I have -

Q. Initial mode of validation?
Q. How long did it take to build?
Q. How long did it take to get the first customer?
Q. Initial investment for marketing? and Modes?
Q. How did you get feedback?
Q. What was your marketing strategy?
Q. How did you do growth hacking?
Q. Was it your first startup/product/side project?
Q. Was it a side project or full time?
Q. Did the founder have prior experience in the field?

Would you like to add anything to this?
What would you like to learn from such an analysis? Any suggestions?
