johncampbell An ideal theme for startups will be the one that doesn’t require setup and the startups can use it without any problem.
How would this theme know the use case it is being applied to? Would the theme for a medical based startup work just as well for a car rental startup?
Just pick a theme you like, no one can answer this question for you. I may really like and you use Divi but you may really not like its layout.
This is like crowd-sourcing your favourite colour.
