Different sector, but I'd say Blackmagic Design seems to be run by people who actually use their own products and care about both product experience and engineering.

In the creative industry there is a bunch of these "boutique" companies that places great care on the final experience. Probably Blackmagic Design is no longer "boutique" to be fair, but seems they still got the culture right.

Valve and the few sane startups / small/mid sized companies you can be lucky enough to end up in.

I was part of the transformation of a healthy mid size engineering led startup company that got taken over by MBAs and Indian employees and saw the whole lifecycle.
