Totally off topic, but the term market verticals was new to me, so I googled it... It's definition is really strange for the used term. I expected something about verticality, like how apple provides their devices - with everything being provided by them: hardware, software and the shop it's being sold in. Or how BYD is creating their EVs, with everything coming from their own factories etc

But instead, it's about specializing your product to the needs of specific customers / finding a niche and then provide exactly the service they desire. How is that in any way vertical?

Etymology is strange
