You might disagree with these examples but:
A stock trading company, IT stuff are support for the real employees, the traders. You have a trader, you have a trading company. The programmers are just support for them.
Animated Movies (even pixar). Sure, there are important software devs but the real staff at pixar are animators. They can ship animations with off the shelf software or paper and pencil. In house software devs are super important but at the end of the day if all they had was animators they could still ship animation.
Lawyer firms, Medical Facilities: Yea, they need IT staff to help run things but they can function with just lawyers or just doctors.
VS say Apple, Google, Facebook, Microsoft. No devs, no company.
Video Game companies used to be and probably mostly still are this way. No software devs no product ships. That might be fraying as tools get better.
