I’ve not started a company yet and I am just concentrating on getting my certs. I have all of the rotorcraft ones that are available and just 3-4 of the heavier aircraft ones left to get.
I’ve been waiting to see if a favourite mission type emerges for me, before setting up my first company and perhaps sadly, the helicopter S&R is the one that is currently “pushing my buttons”. If this carries on though, I might need to reconsider.
