This size of company and mindset seems pretty well served by MicroConf [0], which tends somewhat to the bootstrapping crowd but is very much not the "4 hour work week" crowd.
... Is that what you mean by "optimize for lifetyle"? "lifestyle business" is used as kind of epithet in some circles, as an "othering" term to identify people who don't work as hard as they do, but the MicroConf audience has a lot of people who want to grow their companies as much as is reasonably possible, but with non-negotiable ideas about family time, taking actual vacations instead of working vacations, etc.
One of the creators of MicroConf also is one of the hosts of the podcast "Startups for the Rest of Us" [1], which I don't see talked about very much on HN but which is very much my jam.
